1. Installation

Installation of the XCAP software should be performed prior to installation of the PIXCI® SV4 imaging board. Install XCAP software by following the instructions in the XCAP Software Installation chapter in this manual. After installation of the software, follow the instructions below to install the PIXCISV4 imaging board.

The PIXCI® SV4 imaging board, for the PCI bus, is packed in a static dissipative bag. Please keep the bag and box in which the board was shipped should the need arise to return the board. Prior to opening the bag, place the bag near the PC into which the board will be installed.

  1. Remove power or turn off the PC power switch.
  2. Remove the cover from the PC (if one is used with the PC) into which the PIXCI® SV4 imaging board is to be installed.
  3. Select a vacant PCI bus slot and remove the metal bracket and screw covering the back panel slot with which it is aligned. Consult the reference manual for the PC if there is any doubt about which slot is a PCI bus slot.
  4. A static free area for installation is adviseable. Use of a wrist strap that is connected to the PC or to the static free area is suggested. Since walking across carpet will generate static electricity, keep your feet stationary while removing the PIXCI® SV4 imaging board from the antistatic bag. Hold the bag and touch the PC at the same time, or place the bag on the PC chassis and touch the chassis to dissipate the static charge that may have been created while transporting the board to the PC.
  5. Remove the PIXCI® SV4 imaging board from the antistatic bag and push it into the PCI bus connector. This can require up to 15 pounds of force. Do not use too much force as the board may not be inserted into the connector correctly, and the result can be damage to the connector or the board.
  6. Replace the screw to secure the PIXCI® SV4 imaging board in the slot.
  7. Remove power from the video source to be connected to the PIXCI® SV4.
  8. Connect the video source to either the S-Video input connector (for S-Video sources) or to one of the two BNC connectors (for NTSC or PAL sources).
  9. Apply power to the PC and to the video source.
  10. Power up the camera, PC, and monitor(s).
  11. Operate XCAP by following the instructions in in the XCAP Software Guide chapter in this manual.
  12. Check for display of the video source on the VGA monitor by clicking on the Capture and then the Snap menu in the View window or by using the shortcut menu.
  13. The XCAP software defaults to the S-Video input connector for the video source. The video input source can be selected by clicking on the desired connector of the bracket view of the board in the Capture & Adjust, window. The selected video input connector is highlighted in red. If a video input is selected that does not have a video timing source connected, a blue image will be displayed.
  14. If it is not possible to display an image from the video source, consult the chapter ''In Case of Trouble'' in this manual.
  15. Replace the PC's cover (if one is used).

Caution: Turn the power to the PC and the video source off prior to connecting video sources to the PIXCI® SV4.

1.1. Memory, Motherboard, and VGA

The size and the number of images that can be stored in DRAM on the motherboard is a function of the amount of DRAM that is not used by software. EPIX' XCAP requires at least one megabyte of free DRAM for image storage. If more free DRAM is available, it can be used for image sequence storage.

The PIXCI® SV4 imaging board can capture and store full resolution color images to DRAM on a burst mode PCI motherboard provided that other devices do not compete for PCI bus bandwidth. The data transfer capabilities of the motherboard may limit the size of the image that the PIXCI® SV4 imaging board can transfer to memory on the motherboard. Some PCI motherboards do not support burst mode on the PCI bus. Some PCI motherboards must have their configuration ROM set to enable PCI bus burst mode. PCI bus transfers from other devices will compete for data transfer time with images to be transferred from the PIXCI® SV4 imaging board to memory on the motherboard. ISA bus transfers will also compete for data transfer time with images to be transferred from the PIXCI® SV4 imaging board to memory on the motherboard. If a PC or motherboard has not yet been selected, contact EPIX for suggested motherboards.

The capabilities of the S/VGA board may limit the number of images that can be displayed per second, the number of colors that can be displayed, or the size of the image that can be displayed. An AGP bus VGA board is preferred and at least a PCI bus S/VGA board is recommended to display images from the PIXCI® SV4 imaging board. If an S/VGA board has not yet been selected, contact EPIX for suggested S/VGA boards.

EPIX can provide a complete imaging system including camera, cables, power supply, and computer with the PIXCI imaging board and XCAP software installed.

2. Connectors

The PIXCI® SV4 imaging board has four connectors which are accessible thru the bracket that mounts the board to the computer chassis. From the top of the bracket to the bottom, the connectors are: Y/C, BNC1, BNC2, and DSUB. Silkscreen labels identify each connector on the PIXCI® SV4 imaging board.

2.1. The PIXCI® SV4 Imaging Board Video Signal Descriptions

YC, is the S-Video signal input connector. The ''Y'' signal level is 0 to 1V terminated with 75Ohm to ground. The ''C'' signal level is 0 to 0.714V terminated with 75Ohm to ground. The Y and C inputs have low pass filters in the video path. 








S-Video Connector

BNC1 is an analog video input connector. The analog video input signal level should be 1 volt peak to peak with the video portion positive and the sync tips negative. The minimum composite video input signal that can be amplified to provide 0 thru 255 grey levels is 0.4 volts peak to peak. The maximum composite video input signal that can be amplified to provide 0 thru 255 grey levels is 2.5 volts peak to peak. The input is terminated in 75Ohm to ground. The BNC1 video input has a low pass filter in the video path.

BNC2, is identical to BNC1.

2.2. DB15 Connector

The connector is a female 15 pin D-Subminiature connector (AMP PN 748390-5). Eight pins are used for external inputs and outputs. Seven pins are connected to ground. The signal levels are TTL. Each signal has a 1K ohm pull-up resistor to +5 volts. EPIX' XCAP software treats bits 0 thru 3 as inputs and bits 4 thru 7 as outputs. 








DB15 Connector

3. Software Installation

XCAP-Plus, XCAP-Std, or XCAP-Lite, are easy to install, by following the instructions below.

While XCAP is easy to install, like most manufacturers of PC software, we recommend as a precaution that a hard disk backup be performed before installing XCAP.

3.1. For Windows 95 - Windows 98 - Windows ME

  1. Install Files:
    1. If XCAP is provided on diskette(s):
      1. Insert XCAP diskette #1 into the A: or B: drive.
      2. Execute the SETUP program, from a command prompt, or via the Windows ''Start'', ''Run'': 
            > A:SETUP
or
    > B:SETUP
      3. Follow the installation program's directions, such as to select an installation directory, and insert additional diskettes (depending upon version) as instructed.
    2. If XCAP is provided on a compact disk (CD):
      1. If your PC is set to allow automatic execution of loaded CDs, the CD's interactive index program will be executed automatically. Otherwise, execute the index program, from a command prompt, or via the Windows ''Start'', ''Run'': 
            > Z:SETUP       (replace Z with drive letter for your CD)
      2. Select ''Setup PIXCI(R) Imaging Software'' and ''XCAP Imaging Application''. Click ''OK''.
      3. Follow the installation program's directions, such as to select an installation directory.
    3. If XCAP is provided via the internet:
      1. Download: 
        ftp.epixinc.com/software/xcap_v21/XCAPWI.EXE
        from the EPIX, Inc. ftp site.
      2. Execute the downloaded program, from a command prompt, or via the Windows ''Start'', ''Run'': 
            > XCAPWI.EXE
      3. Follow the installation program's directions, such as to select an installation directory.
      4. Delete the downloaded .EXE file from your PC's hard drive.
    4. The installation procedure creates a new program group, containing XCAP and several .TXT files. The .TXT files contain these installation instructions, a list of distributed files, corrections or additions to this manual, or other up-to-date information. One file, PCITIPS.TXT, contains the PC Configuration Tips, which provides tips for resolving hardware and software conflicts.
  2. Create Shortcut - Drag & Drop (optional):
    1. From the program group created by the installation program, click and drag the icon for XCAP over to the desktop and drop.
  3. Create Shortcut - Manual (optional):
    1. Right click on the Desktop.[1]
    2. Select ''New''.
    3. Select ''Shortcut''.
    4. Set: 
          Command Line:   InstallDir \ XCAPWXX
    Name:           XCAP
      replacing ''InstallDir'' with the name of the installation directory chosen above. Select ''OK''.
  4. Install Authorization Key (for XCAP-Plus and XCAP-Std):
    1. XCAP-Plus and XCAP-Std, but not XCAP-Lite, are provided with either a printer port authorization key or a USB authorization key.

      The printer port authorization key is approximately the size and shape of a printer cable's connector (5.5×4.5×1.6 cm), but having 25 pin connectors at both ends and no cable attached. If provided, connect the authorization key to printer port 1, 2, or 3. If a printer cable was attached to the printer port, reconnect the printer cable to the back of the authorization key. The authorization key will not affect normal printer operation.

      Do not connect the printer port authorization key to a 25 pin serial (RS-232) port, or to any other interface which happens to use the same style connector; the authorization key will not function, might be permanently damaged, and the warranty will be void!

      The USB port authorization key is approximately the size of a small finger (6.0×1.6×0.8 cm), having a USB standard 4 pin connector at one end. If provided, connect the authorization key to a USB port.

      The authorization key must remain attached, to the printer port or USB port as appropriate, while XCAP is running. If the authorization key is missing, or disconnected while XCAP is running, then XCAP-Plus or XCAP-Std will behave similar to the XCAP-Lite version; selected image processing and analysis tools will not be operational.

    2. Run the authorization key utility program provided with XCAP by ''Start'', ''Run'': 
          > C:\XCAP\HLDINST -install
    3. Or, in command prompt mode, switch to the chosen installation directory: 
          > CHDIR C:\XCAP
      and execute: 
           HLDINST  -install
      to run the authorization key utility program.
    4. For USB port authorization keys, in some versions of Windows 95 and 98, it is also necessary to: 
          Start
    Settings
    Control Panel
    Add New Hardware
    ...
    5. Note that support for the USB port authorization key under Windows 95 requires OSR2 or later with the USB supplement.
  5. Install PIXCI® Imaging Board Driver:
    1. Under Windows 95/98/ME, the Windows' Device Manager must be used for initial installation of the PIXCI® driver.

      If the PIXCI® imaging board was not yet installed, the first time Windows starts after installation Windows will notice the new device and inquire.

      The first time Windows 95 starts after installation of the PIXCI® imaging board, a pop-up window titled ''New Hardware Found'' with messages ''PCI Multimedia Device'' and ''Select which driver you want to install for your new hardware'' will appear. Select the ''Driver from disk provided by hardware manufacturer'' option and click ''OK''. A pop-up window with the message ''Insert the manufacturer's installation disk ...'' and ''Copy manufacturer's files from ...'' will appear. Click ''Browse'', select path and file DRIVERS\WIN95\EPIXXCW5.INF (EPIXXC32.INF for version 2.0 and earlier) within the chosen installation directory, such as C:\XCAP\DRIVERS\WIN95\EPIXXCW5.INF, and click ''OK'' and ''OK''. Do not accept the offer to ''Reboot''; a full shutdown and reboot is required. Some later releases of Windows 95 behave similar to Windows 98; the inquiries and responses may instead follow the steps below.

      The first time Windows 98 starts after installation of the PIXCI® imaging board, a pop-up window with the message ''New PCI Multimedia Device'' will flash by. Next a pop-up window with the message ''The wizard searches for new driver for PCI Multimedia Video Device'' will appear. Click ''Next''. Select ''Search for the best driver for your device''. Click ''Next''. A pop-up window with the message ''Windows will search for new driver ...'' and ''Specify Location'' will appear. Enter path DRIVERS\WIN95 within the chosen installation directory, such as C:\XCAP\DRIVERS\WIN95, and click ''Next''. A pop-up window will report that a driver was found, namely C:\XCAP\DRIVERS\WIN95\EPIXXCW5.INF (EPIXXC32.INF for version 2.0 and earlier). Click ''Next'' and ''Finish''.

      The first time Windows ME starts after installation of the PIXCI® imaging board, a pop-up window with the message ''New PCI Multimedia Video Device'' will flash by. Next a pop-up window with the message ''Windows has found the following new hardware:'' will appear. Select ''Specify the location of the driver (Advanced)''. Click ''Next''. Select ''Search for the best driver for your device''. Check the box for: ''Specify a location''. Enter path DRIVERS\WINME within the chosen installation directory, such as C:\XCAP\DRIVERS\WINME, and click ''Next''. A pop-up window will report that a driver was found, namely C:\XCAP\DRIVERS\WINME\EPIXXCW5.INF (EPIXXC32.INF for version 2.0 and earlier). Click ''Next'' and ''Finish''.

      If the PIXCI® imaging board was already installed under Windows 95 or 98, and ''Cancel'' was clicked when Windows started and announced the presence of new ''PCI Multimedia Hardware'', then instruct Windows to load the appropriate driver. Click ''Start'', ''Control Panel'', ''System'', ''Device Manager'', and ''Other Devices''. Select ''PCI MultiMedia Video Device'' (which appears if a PIXCI® imaging board driver was never installed), or ''PIXCI(R) Video Capture Board'' (which appears if a PIXCI® imaging board driver was previously installed). Click ''Driver'', ''Change Driver'', and ''Other''. Select ''PCI MultiMedia Video Device'' or ''PIXCI(R) Video Capture Board''. Click ''Have Disk'', select DRIVERS\WIN95 within the chosen installation directory, such as C:\XCAP\DRIVERS\WIN95, and click ''OK''.

      If the PIXCI® imaging board was already installed under Windows ME, and ''Cancel'' was clicked when Windows started and announced the presence of new ''PCI Multimedia Hardware'', then instruct Windows to load the appropriate driver. Click ''Start'', ''Settings'', ''Control Panel'', ''System'', if System is not listed, click on ''view all Control Panel options'', ''Device Manager'', and ''Other Devices''. Select ''PCI MultiMedia Video Device'' (which appears if a PIXCI® imaging board driver was never installed), or ''PIXCI(R) Video Capture Board'' (which appears if a PIXCI® imaging board driver was previously installed). Click on the ''Properties'' button. Click on the ''Driver'' Tab, and the click on ''Change Driver'', or ''Update Driver''. Next a pop-up window with the message ''This wizard searches for updated drivers for:'' followed by ''PCI MultiMedia Video Device'' (which appears if a PIXCI® imaging board driver was never installed), or ''PIXCI(R) Video Capture Board'' (which appears if a PIXCI® imaging board driver was previously installed). Select ''Specify the location of the driver (Advanced)''. Click ''Next''. Select ''Search for the best driver for your device''. Check the box for: ''Specify a location''. Enter path DRIVERS\WINME within the chosen installation directory, such as C:\XCAP\DRIVERS\WINME, and click ''Next''. A pop-up window will report that a driver was found, namely C:\XCAP\DRIVERS\WINME\EPIXXCW5.INF (EPIXXC32.INF for version 2.0 and earlier). Click ''Next'' and ''Finish''.

      Note that the ''quick reboot'' offered by (some versions of the) Device Manager does not properly install the PIXCI® board's driver; a full shutdown and reboot is required. The shutdown and reboot can be delayed until after the installation is completed.

  6. Set Frame Buffer Memory Size (optional):
    1. By default, 4 megabytes of frame buffer memory is allocated.
    2. Under Windows 95/98/ME, frame buffer memory must be allocated during Windows' initialization, as specified in the Windows' SYSTEM.INI file. If additional frame buffer memory is desired, then at the end of the Windows' SYSTEM.INI file, add a section: 
          [EPIX_XC]
    PIXCI=-IM <memorysize>
      replacing the ''<memorysize>'' with the desired memory size in Kbytes. Windows must be rebooted for the new specification to take effect.

      Windows 95/98/ME limits the maximum amount of allocatable frame buffer memory, dependent upon what other devices are installed, the total PC memory size, and other factors.

      Less than the requested amount of frame buffer memory may be provided by Windows. If no memory could be allocated, the PIXCI® imaging board will not be usable; reporting ''Can't allocate frame buffer memory''. Otherwise, within XCAP, the amount of frame buffer memory can be checked under PIXCI®, PIXCI® Open/Close.

  7. Configure S/VGA:
    1. A ''High Color (16 bit or 65536 Color)'', ''True Color (24 bit or 16777216 Color)'', or ''True Color (32 bit)'' setting for the display adapter (S/VGA) is required for proper display of images and overlay graphics. The ''True Color (24 bit or 16777216 Color)'' or ''True Color (32 bit)'' is suggested for higher quality, and quicker, display of images and overlay graphics. This may be checked and/or modified via Windows ''Start'', ''Control Panel'', ''Display'', ''Settings''.
    2. In Windows 95, under ''Control Panel'', ''Display'', ''Plus!'', the ''Show window contents while dragging'' must be disabled (this feature is not present in older versions of Windows 95). Or in Windows 98/ME, under ''Control Panel'', ''Display'', ''Effects'', the ''Show window contents while dragging'' must be disabled.
    3. After changing the settings a full shutdown and CTRL+ALT+DEL reboot should be used. The quick restart offered by older versions of Windows 95, and the dynamic VGA reconfiguration performed by newer versions of Windows 95, may not re-initialize all devices properly.
  8. Reboot Windows.
  9. XCAP is now ready to run, clicking ''Start'', ''Programs'', ''XCAP Imaging'', and finally ''XCAP for Windows''.

3.2. Windows 95 - Windows 98 - Windows ME - Esoterica

3.2.1. Windows 95/98/ME - Manual Installation

Use of EPIXXCW5.INF (EPIXXC32.VXD for version 2.0 and earlier), above, provides automatic installation of EPIXXCW5.VXD (EPIXXC32.VXD for version 2.0 and earlier) in most circumstances. The following information allows manual installation, correcting problems, or integration with an OEM's procedures.

  1. The EPIXXCW5.VXD (EPIXXC32.VXD for version 2.0 and earlier) must be copied to the Windows SYSTEM directory, typically: 
        C:\WINDOWS\SYSTEM
  2. Using the Registry Editor (REGEDIT) provided with Windows, create an entry such as: 
        HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Unknown\0000
    replacing the \0000, if such an entry already exists, with the next available sequential number. This entry must contain: 
        DevLoader=      "epixxc32.vxd"                      (for version 2.0-)
    DevLoader=      "epixxcw5.vxd"                      (for version 2.1+)

    where the ''0000'' is replaced by the sequential number used in the previous step.
  4. Reboot Windows.

3.2.2. Windows 95/98 - Forcible Frame Buffer Memory Allocation

As described above, frame buffer memory allocated by EPIXXCW5.VXD (EPIXXC32.VXD for version 2.0 and earlier) during Windows startup is limited to a small percentage of total PC memory.

A larger frame buffer memory can often be obtained by reserving memory before Windows starts:

  1. In C:\CONFIG.SYS[2], add a line: 
        DEVICE=C:\XCAP\DRIVERS\WIN95\EPIXXC.SYS -IM <framebuffermemorysize>
    or 
       DEVICE=C:\XCAP\DRIVERS\WIN95\EPIXXC.SYS -OS <reservememorysize>
    after DEVICE=HIMEM.SYS, replacing ''<framebuffermemorysize>'' with the desired frame buffer memory size, in Kbytes. Alternately, the second form reserves ''<reservememorysize>'' Kbytes, for Windows and allocates (almost) all of the remaining memory for use as frame buffer memory.
  2. Edit the Windows' SYSTEM.INI file, add a section: 
        [EPIX_XC]
    PIXCI=-IM 0
    so that EPIXXCW5.VXD (EPIXXC32.VXD for version 2.0 and earlier) doesn't reserve and waste additional frame buffer memory.
  3. Reboot Windows.

This technique allows most of the PC's memory to be reserved as frame buffer memory (e.g. typically all but 8 or 16 megabytes, as required by Windows). However, the memory is unavailable to Windows, even when the PIXCI® imaging board's driver is not open.

If the specified amount of frame buffer memory could not be allocated, EPIXXC.SYS will attempt to allocate smaller amounts. If no memory can be allocated EPIXXC.SYS, will display an error message during Windows startup, and XCAP will not run, stating ''Can't allocate frame buffer memory''.

This alternate frame buffer allocation method is not available under Windows ME.

3.2.3. Windows ME - Forcible Frame Buffer Memory Allocation

As described above, frame buffer memory allocated by EPIXXCW5.VXD during Windows startup is limited to a small percentage of total PC memory.

A larger frame buffer memory can be obtained by limiting the amount of memory recognized by Windows ME, and then instructing EPIXXCW5.VXD to explicitly use a section of memory without allocating it from Windows:

  1. Restrict Windows to use no more than a set amount of memory: Edit the Windows' SYSTEM.INI file, add or modify the MaxPhysPage entry, specifying the maximum amount of memory to be used by Windows in units of 4096 pages, expressed in hexadecimal: 
        [386Enh]
    MaxPhysPage=4000    ;; 64 Mbytes in 4096 byte pages, in hexadecimal
  2. Edit the Windows' SYSTEM.INI file, add a section and entry: 
        [EPIX_XC]
    PIXCI= -IA <image_memory_adrs_in_kbyte>
           -IM <size_of_image_memory_in_kbyte>
           -MB 16384
    In practice, all three fields are on the same line. Be certain that the -IA address is equal to (or above) the specified /MaxPhysPage limit - including exact base2 to base10 conversions! (i.e. for MaxPhysPage=4000 or 64 Mbyte, the smallest legal value of -IA is 65536, not 64000!). Likewise, be certain that the -IA plus -IM values do not exceed the amount of memory available!
  3. Reboot.

For example, for a PC with 256 megabyte of memory, allocating 192 Mbyte for Windows and the remainder for frame buffer memory, use: 

    MaxPhysPage=C000
and 
    PIXCI = -IA 196608 -IM 65536 -MB 16384

3.2.4. Windows 95/98/ME - Authorization Key - Manual Installation

Use of HLDINST.EXE, above, provides automatic installation of the printer port authorization key's driver, needed under Windows 95/98/ME, for XCAP-Plus and XCAP-Std (but not needed for XCAP-Lite). The following information allows manual installation, correcting problems, or integration with an OEM's procedures for the printer port version of authorization keys.

  1. The file HARDLOCK.VXD must be copied to the Windows SYSTEM directory, typically: 
        C:\WINDOWS\SYSTEM
    or placed in the same directory as XCAP, typically: 
        C:\XCAP
Normally, all LPT ports are scanned for the authorization key. Should other hardware use, or overlap, one of the LPT I/O port addresses, the search may be restricted to specific I/O ports. In AUTOEXEC.BAT, specifying: 
    SET HL_SEARCH=378p
    SET HL_SEARCH=278p,378p
forces only the I/O port addresses listed (in hexadecimal) to be searched. Note that setting HL_SEARCH from a DOS box has no effect, as the setting is not ''carried back'' from DOS into the Windows 95/98/ME environment.

3.3. For Windows NT

XCAP requires Windows NT Version 4 with Service Pack 3 or later. You must be logged on an Administrator, or have equivalent privileges, to complete the installation procedure.

  1. Install Files:
    1. If XCAP is provided on diskette(s):
      1. Insert XCAP diskette #1 into the A: or B: drive.
      2. Execute the SETUP program, from a command prompt, or via the Windows ''Start'', ''Run'': 
            > A:SETUP
or
    > B:SETUP
      3. Follow the installation program's directions, such as to select an installation directory, and insert additional diskettes (depending upon version) as instructed.
    2. If XCAP is provided on a compact disk (CD):
      1. If your PC is set to allow automatic execution of loaded CDs, the CD's interactive index program will be executed automatically. Otherwise, execute the index program, from a command prompt, or via the Windows ''Start'', ''Run'': 
            > Z:SETUP       (replace Z with drive letter for your CD)
      2. Select ''Setup PIXCI(R) Imaging Software'' and ''XCAP Imaging Application''. Click ''OK''.
      3. Follow the installation program's directions, such as to select an installation directory.
    3. If XCAP is provided via the internet:
      1. Download: 
        ftp.epixinc.com/software/xcap_v21/XCAPWI.EXE
        from the EPIX, Inc. ftp site.
      2. Execute the downloaded program, from a command prompt, or via the Windows ''Start'', ''Run'': 
            > XCAPWI.EXE
      3. Follow the installation program's directions, such as to select an installation directory.
      4. Delete the downloaded .EXE file from your PC's hard drive.
    4. The installation procedure creates a new program group, containing XCAP and several .TXT files. The .TXT files contain these installation instructions, a list of distributed files, corrections or additions to this manual, or other up-to-date information. One file, PCITIPS.TXT, contains the PC Configuration Tips, which provides tips for resolving hardware and software conflicts.
  2. Create Shortcut - Drag & Drop (optional):
    1. From the program group created by the installation program, click and drag the icon for XCAP over to the desktop and drop.
  3. Create Shortcut - Manual (optional):
    1. Right click on the Desktop.[3]
    2. Select ''New''.
    3. Select ''Shortcut''.
    4. Set: 
          Command Line:   InstallDir \ XCAPWXX
    Name:           XCAP
      replacing ''InstallDir'' with the name of the installation directory chosen above. Select ''OK''.
  4. Install Authorization Key (for XCAP-Plus and XCAP-Std):
    1. XCAP-Plus and XCAP-Std, but not XCAP-Lite, are provided with either a printer port authorization key or a USB authorization key.

      The printer port authorization key is approximately the size and shape of a printer cable's connector (5.5×4.5×1.6 cm), but having 25 pin connectors at both ends and no cable attached. If provided, connect the authorization key to printer port 1, 2, or 3. If a printer cable was attached to the printer port, reconnect the printer cable to the back of the authorization key. The authorization key will not affect normal printer operation.

      Do not connect the printer port authorization key to a 25 pin serial (RS-232) port, or to any other interface which happens to use the same style connector; the authorization key will not function, might be permanently damaged, and the warranty will be void!

      The USB port authorization key is approximately the size of a small finger (6.0×1.6×0.8 cm), having a USB standard 4 pin connector at one end. If provided, connect the authorization key to a USB port.

      The authorization key must remain attached, to the printer port or USB port as appropriate, while XCAP is running. If the authorization key is missing, or disconnected while XCAP is running, then XCAP-Plus or XCAP-Std will behave similar to the XCAP-Lite version; selected image processing and analysis tools will not be operational.

    2. Run the authorization key utility program provided with XCAP by ''Start'', ''Run'': 
          > C:\XCAP\HLDINST -install
    3. Or, in command prompt mode, switch to the chosen installation directory: 
          > CHDIR C:\XCAP
      and execute: 
           HLDINST  -install
      to run the authorization key utility program.
  5. Install PIXCI® Imaging Board Driver:
    1. If the PIXCI® imaging board's driver was not loaded when the PC was powered up (as described under Hardware Installation), instruct Windows to load the appropriate driver: Click ''Start'', ''Programs'', and ''Windows NT Explorer''. Within the chosen installation directory, such as C:\XCAP, find and highlight file DRIVERS\WINNT\EPIXXCWT.INF (EPIXXCNT.INF for version 2.0 and earlier). From the menu bar, select ''File'' and ''Install''.
  6. Configure S/VGA:
    1. A ''High Color (16 bit or 65536 Color)'', ''True Color (24 bit or 16777216 Color)'', or ''True Color (32 bit)'' setting for the display adapter (S/VGA) is required for proper display of images and overlay graphics. The ''True Color (24 bit or 16777216 Color)'' or ''True Color (32 bit)'' is suggested for higher quality, and quicker, display of images and overlay graphics. This may be checked and/or modified via Windows ''Start'', ''Settings'', ''Control Panel'', ''Display'', ''Settings''.
    2. Under ''Start'', ''Settings'', ''Control Panel'', ''Display'', ''Effects'', the ''Show window contents while dragging'' must be disabled.
  7. Reboot Windows.
  8. XCAP is now ready to run, clicking ''Start'', ''Programs'', ''XCAP Imaging'', and finally ''XCAP for Windows''.

3.4. Windows NT Esoterica

3.4.1. Windows NT - Manual Installation

Use of EPIXXCWT.INF (EPIXXCNT.INF for version 2.0 and earlier), above, provides automatic installation of EPIXXCWT.SYS (EPIXXCNT.SYS for version 2.0 and earlier) in most circumstances. The following information allows manual installation, correcting problems, or integration with an OEM's procedures.

  1. The EPIXXCWT.SYS (EPIXXCNT.SYS for version 2.0 and earlier) must be copied to the Windows SYSTEM32\DRIVERS directory, typically: 
        C:\WINNT\SYSTEM32\DRIVERS
  2. Using the Registry Editor (REGEDIT) provided with Windows, create an entry such as: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCWT  (version 2.1+)
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCNT  (version 2.0-)
    This entry must contain: 
        ErrorControl  =  0x00000001
    Group         =  "Extended base"
    Start         =  0x00000001
    Type          =  0x00000001
    and may, as described below, also contain: 
        PIXCI         =  "-IM <memorysize>"
    Create an entry such as: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\System\EPIXXCWT  (version 2.1+)
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\System\EPIXXCNT  (version 2.0-)
    This entry must contain: 
        EventMessageFile = "%SystemRoot%\System32\IoLogMsg.dll"
    TypesSupported   = 0x00000007
  3. Shut down and restart Windows.

3.4.2. Windows NT - Frame Buffer Memory Allocation

Under Windows NT, frame buffer memory must be allocated during Windows' initialization.

The requested frame buffer memory size must be specified in the Registry entry described above, using an entry named ''PIXCI'', such as: 

    PIXCI         =  "-IM <memorysize>"
replacing the ''<memorysize>'' with the desired memory size in Kbytes. If no frame buffer memory size is specified, a default size of 4 megabytes is used. Windows must be rebooted for the new specification to take effect.

Windows NT limits the maximum amount of allocatable frame buffer memory, dependent upon what other devices are installed, the total PC memory size, and other factors. Using the Control Panel's Device Manager to select Boot or System priority startup for EPIXXCWT.SYS (EPIXXCNT.SYS for version 2.0 and earlier) allows more frame buffer memory to be allocated than selection of Automatic startup.

Less than the requested amount of frame buffer memory may be provided by Windows. If no memory could be allocated, XCAP will not run, stating ''Can't allocate frame buffer memory''. Otherwise, within XCAP, the number of available frame buffers can be checked under PIXCI®, PIXCI® Video Setup, Resolution. As the frame buffer memory is allocated once during Windows initialization; the contents of frame buffers are retained as XCAP is closed and restarted, but lost if Windows is restarted.

3.4.3. Windows NT - Forcible Frame Buffer Memory Allocation

As described above, frame buffer memory allocated by EPIXXCWT.SYS (EPIXXCNT.SYS for version 2.0 and earlier) during Windows startup may be limited to a small percentage of total PC memory.

A larger frame buffer memory can be obtained by limiting the amount of memory recognized by Windows NT, and then instructing EPIXXCWT.SYS (EPIXXCNT.SYS for version 2.0 and earlier) to explicitly use a section of memory without allocating it from Windows NT:

  1. Edit C:\BOOT.INI, restricting Windows NT to use no more than a set amount of memory: by copying an existing configuration line, adding /MAXMEM=XX (where XX is in Mbytes) and changing the prompt name, such as changing: 
        [operating systems]
    multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows NT V 4.00"
    to 
        [operating systems]
    multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows NT V 4.00 [NT=64M PIXCI=256M]"  /MAXMEM=64
    multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows NT V 4.00"
    Do not copy this new line as shown above; the first portion of the line must be copied from an existing configuration line in your C:\BOOT.INI file. The text between quotes appears as a boot selection prompt, use of ''[NT=64M PIXCI=256M]'' is a suggested reminder, but not required.

    Also in C:\BOOT.INI, change the timeout selection to be greater than 0: 

        [boot loader]
    timeout=30
    Otherwise the BOOT.INI configuration options will not be shown when Windows starts.

    Keeping the original configuration line, as a boot selection option, is highly recommended as a backup.

  2. Edit the registry entry: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCWT  (version 2.1+)
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCNT  (version 2.0-)
    On the ''PIXCI'' field add: 
        -IA <image_memory_adrs_in_kbyte>
    -IM <size_of_image_memory_in_kbyte>
    -MB 8192
    In practice, all three fields are on the same line. Be certain that the -IA address is equal to (or above) the specified /MAXMEM limit - including exact base2 to base10 conversions! (i.e. for /MAXMEM=64, the smallest legal value of -IA is 65536, not 64000!). Likewise, be certain that the -IA plus -IM values do not exceed the amount of memory available!
  3. Reboot, using the newly added boot selection.

For example, for a PC with 1 gigabyte of memory, allocating 256 Mbyte for Windows and the remainder for frame buffer memory, use: 

    /MAXMEM=256
in C:\BOOT.INI, and use: 
    PIXCI = -IA 262144 -IM 786432 -MB 8192
in the registry entry. Note that 262144 is 256×1024, and 786432 is (1024-256)×1024.

Note that if this memory allocation method is used, program access to image data may be slower. Thus, the video display rate (and image processing) may be slower, but the video capture rate (such as sequence capture) is not adversely affected. This method of memory allocation is primarily used for video rate acquisition of long sequences, followed by off-line analysis or saving of the sequence.

3.4.4. Windows NT - Authorization Key - Manual Installation

Use of HLDINST.EXE, above, provides automatic installation of the printer port authorization key's driver, needed under Windows NT, for XCAP-Plus and XCAP-Std (but not needed for XCAP-Lite). The following information allows manual installation, correcting problems, or integration with an OEM's procedures for the printer port version of authorization keys.

  1. The file HARDLOCK.SYS must be copied to the Windows SYSTEM32\DRIVERS directory, typically: 
        C:\WINNT\SYSTEM32\DRIVERS
  2. The file HLVDD.DLL must copied to the Windows SYSTEM directory, typically: 
        C:\WINNT\SYSTEM
    or placed in the same directory as XCAP, typically: 
        C:\XCAP
  3. Using the Registry Editor (REGEDIT) provided with Windows, create an entry such as: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HardLock
    This key must contain values: 
        ErrorControl  =  0x00000001
    Group         =  "Extended Base"
    Start         =  0x00000002
    Type          =  0x00000001
    or, if using REGEDT32, the values should appear as: 
        ErrorControl:REG_DWORD:0x1
    Group:REG_SZ:ExtendedBase
    Start:REG_DWORD:0x2
    Type:REG_DWORD:0x1
  4. Shut down and restart Windows for the new registry entries to take effect.
  5. If the authorization key is connected to a non-standard printer port, an additional entry may be required: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HardLock\Parameters
    which contains a value: 
        IoPortAddress0  = 0x????            (for REGEDIT)
    IoPortAddress0:REG_DWORD:0x????     (for REGEDT32)
    where the ''????'' is replaced with the parallel port's I/O address in hexadecimal. As before, Windows must be shut down and restarted.

      and execute: 
           HLDINST  -install
      to run the authorization key utility program.
  5. Install PIXCI® Imaging Board Driver:
    1. Under Windows 2000, the Windows' Device Manager must be used for initial installation of the PIXCI® driver.

      If the PIXCI® imaging board was not yet installed, the first time Windows starts after installation Windows will notice the new device and inquire.

      The first time Windows 2000 starts after installation of the PIXCI® imaging board, a pop-up window with the message ''Multimedia Video Controller'' will flash by. Next a pop-up window with the message ''Welcome to the Found New Hardware Wizard'' will appear. Click ''Next''. Select ''Search for the best driver for your device''. Click ''Next''. Check the box for: ''Specify a location''. Enter path DRIVERS\WIN2K within the chosen installation directory, such as C:\XCAP\DRIVERS\WIN2K, and click ''Next''. A pop-up window will report that a driver was found, namely C:\XCAP\DRIVERS\WIN2K\EPIXXCW2.INF. Click ''Next''. A pop-up window will report that a ''Digital Signature was not found''. Click ''Yes''. A pop-up window with the message ''Completing the Found New Hardware Wizard'' will state that ''This device is not configured correctly. (Code 1)''; this error indicates that the newly installed driver will be functional only after a reboot. Click ''Finish'' and reboot Windows.

      If the PIXCI® imaging board was already installed under Windows 2000, and ''Cancel'' was clicked when Windows started and announced the presence of a new ''Multimedia Video Controller'', then instruct Windows to load the appropriate driver. Click ''Start'', ''Settings'', ''Control Panel'', ''System'' (if ''System'' is not listed, click on ''view all Control Panel options''), ''Device Manager'', and ''Other Devices'' or ''Imaging Devices''. Select ''PCI MultiMedia Video Device'' (which appears if a PIXCI® imaging board driver was never installed), or ''PIXCI(R) Video Capture Board'' (which appears if a PIXCI® imaging board driver was previously installed). Double-click on the entry to bring up the ''Properties'' window. Click the ''Driver'' tab, and then click ''Change Driver'', or ''Update Driver''. A pop-up ''Welcome'' window will appear, click ''Next''. A pop-up window with the messages ''This wizard searches for updated drivers for:'' and ''PCI MultiMedia Video Device'' or ''PIXCI(R) Video Capture Board'' will appear. Select ''Search for a suitable driver for my device (recommended)''. Click ''Next''. Check the box for: ''Specify a location''. Enter path DRIVERS\WIN2K within the chosen installation directory, such as C:\XCAP\DRIVERS\WIN2K, and click ''Next''. A pop-up window will report that a driver was found, namely C:\XCAP\DRIVERS\WIN2K\EPIXXCW2.INF. Click ''Next''. A pop-up window will appear stating that a ''Digital Signature was not found''. Click ''Yes''. A pop-up window with the message ''Completing the Found New Hardware Wizard'' will appear and may state that ''This device is not configured correctly. (Code 1)''; this error indicates that the newly installed driver will be functional only after a reboot. Click ''Finish'' and reboot Windows.

  6. Configure S/VGA:
    1. A ''High Color (16 bit or 65536 Color)'', ''True Color (24 bit or 16777216 Color)'', or ''True Color (32 bit)'' setting for the display adapter (S/VGA) is required for proper display of images and overlay graphics. The ''True Color (24 bit or 16777216 Color)'' or ''True Color (32 bit)'' is suggested for higher quality, and quicker, display of images and overlay graphics. This may be checked and/or modified via Windows ''Start'', ''Settings'', ''Control Panel'', ''Display'', ''Settings''.
    2. Under ''Start'', ''Settings'', ''Control Panel'', ''Display'', ''Effects'', the ''Show window contents while dragging'' must be disabled.
  7. Reboot Windows.
  8. XCAP is now ready to run, clicking ''Start'', ''Programs'', ''XCAP Imaging'', and finally ''XCAP for Windows''.

3.6. Windows 2000 Esoterica

3.6.1. Windows 2000 - Manual Installation

Use of EPIXXCW2.INF (EPIXXCNT.INF for version 2.0 and earlier), above, provides automatic installation of EPIXXCW2.SYS (EPIXXCNT.SYS for version 2.0 and earlier) in most circumstances. The following information allows manual installation, correcting problems, or integration with an OEM's procedures.

  1. The EPIXXCW2.SYS (EPIXXCNT.SYS for version 2.0 and earlier) must be copied to the Windows SYSTEM32\DRIVERS directory, typically:

    TypesSupported   = 0x00000007
  3. Shut down and restart Windows.

Under Windows 2000, the Windows NT driver EPIXXCWT.SYS can be, and was previously, used instead of EPIXXCW2.SYS. In contrast to EPIXXCWT.SYS, the EPIXXCW2.SYS is Plug & Play compatible.

3.6.2. Windows 2000/XP - Frame Buffer Memory Allocation

Under Windows 2000/XP, frame buffer memory must be allocated during Windows' initialization.

The requested frame buffer memory size must be specified in the Registry entry described above, using an entry named ''PIXCI'', such as: 

    PIXCI         =  "-IM <memorysize>"
replacing the ''<memorysize>'' with the desired memory size in Kbytes. If no frame buffer memory size is specified, a default size of 4 megabytes is used. Windows must be rebooted for the new specification to take effect.

Windows 2000/XP limits the maximum amount of allocatable frame buffer memory, dependent upon what other devices are installed, the total PC memory size, and other factors.

Less than the requested amount of frame buffer memory may be provided by Windows. If no memory could be allocated, XCAP will not run, stating ''Can't allocate frame buffer memory''. Otherwise, within XCAP, the number of available frame buffers can be checked under PIXCI®, PIXCI® Video Setup, Resolution. As the frame buffer memory is allocated once during Windows initialization; the contents of frame buffers are retained as XCAP is closed and restarted, but lost if Windows is restarted.

3.6.3. Windows 2000/XP - Forcible Frame Buffer Memory Allocation

As described above, frame buffer memory allocated by EPIXXCW2.SYS during Windows startup may be limited to a small percentage of total PC memory.

A larger frame buffer memory can be obtained by limiting the amount of memory recognized by Windows 2000/XP, and then instructing EPIXXCW2.SYS to explicitly use a section of memory without allocating it from Windows 2000/XP:

  1. Edit C:\BOOT.INI, restricting Windows 2000/XP to use no more than a set amount of memory: by copying an existing configuration line, adding /MAXMEM=XX (where XX is in Mbytes) and changing the prompt name, such as changing: 
        [operating systems]
    multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows 2000"
    to 
        [operating systems]
    multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows 2000 [NT=64M PIXCI=256M]"  /MAXMEM=64
    multi(0)disk(0)rdisk(0)partition(7)\WINNT="Windows 2000"
    Do not copy this new line as shown above; the first portion of the line must be copied from an existing configuration line in your C:\BOOT.INI file. The text between quotes appears as a boot selection prompt, use of ''[NT=64M PIXCI=256M]'' is a suggested reminder, but not required.

    Also in C:\BOOT.INI, change the timeout selection to be greater than 0: 

        [boot loader]
    timeout=30
    Otherwise the BOOT.INI configuration options will not be shown when Windows starts.

    Keeping the original configuration line, as a boot selection option, is highly recommended as a backup.

  2. Edit the registry entry: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EPIXXCW2
    On the ''PIXCI'' field add: 
        -IA <image_memory_adrs_in_kbyte>
    -IM <size_of_image_memory_in_kbyte>
    -MB 8192
    In practice, all three fields are on the same line. Be certain that the -IA address is equal to (or above) the specified /MAXMEM limit - including exact base2 to base10 conversions! (i.e. for /MAXMEM=64, the smallest legal value of -IA is 65536, not 64000!). Likewise, be certain that the -IA plus -IM values do not exceed the amount of memory available!
  3. Reboot, using the newly added boot selection.

For example, for a PC with 1 gigabyte of memory, allocating 256 Mbyte for Windows and the remainder for frame buffer memory, use: 

    /MAXMEM=256
in C:\BOOT.INI, and use: 
    PIXCI = -IA 262144 -IM 786432 -MB 8192
in the registry entry. Note that 262144 is 256×1024, and 786432 is (1024-256)×1024.

Note that if this memory allocation method is used, program access to image data may be slower. Thus, the video display rate (and image processing) may be slower, but the video capture rate (such as sequence capture) is not adversely affected. This method of memory allocation is primarily used for video rate acquisition of long sequences, followed by off-line analysis or saving of the sequence.

3.6.4. Windows 2000/XP - Authorization Key - Manual Installation

Use of HLDINST.EXE, above, provides automatic installation of the printer port authorization key's driver, needed under Windows 2000/XP, for XCAP-Plus and XCAP-Std (but not needed for XCAP-Lite). The following information allows manual installation, correcting problems, or integration with an OEM's procedures for the printer port version of authorization keys.

  1. The file HARDLOCK.SYS must be copied to the Windows SYSTEM32\DRIVERS directory, typically: 
        C:\WINNT\SYSTEM32\DRIVERS
  2. Using the Registry Editor (REGEDIT) provided with Windows, create an entry such as: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HardLock
    This key must contain values: 
        ErrorControl  =  0x00000001
    Group         =  "Extended Base"
    Start         =  0x00000002
    Type          =  0x00000001
    or, if using REGEDT32, the values should appear as: 
        ErrorControl:REG_DWORD:0x1
    Group:REG_SZ:ExtendedBase
    Start:REG_DWORD:0x2
    Type:REG_DWORD:0x1
  3. Shut down and restart Windows for the new registry entries to take effect.
  4. If the authorization key is connected to a non-standard printer port, an additional entry may be required: 
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HardLock\Parameters
    which contains a value: 
        IoPortAddress0  = 0x????            (for REGEDIT)
    IoPortAddress0:REG_DWORD:0x????     (for REGEDT32)
    where the ''????'' is replaced with the parallel port's I/O address in hexadecimal. As before, Windows must be shut down and restarted.

4. Getting Started

This chapter will guide the user through the initial steps common to most applications using the PIXCI imaging board: capturing, viewing, examining, and saving images. This guide isn't intended to discuss every feature of every window in XCAP, just the most important features to ''get up and running''.

By following the previous instructions, at this point:

  1. The PIXCI imaging board has been installed.
  2. The camera has been connected to the PIXCI imaging board.
  3. The XCAP software has been installed.
  4. For XCAP-Plus or XCAP-Std, but not XCAP-Lite, the authorization key has been installed on the printer port.
  5. The PIXCI driver for Windows 95/98 or Windows NT, has been installed.
  6. The S/VGA has been set for 16 bits (minimum required), or 24 or 32 bits (preferred), per pixel.
  7. The PC has been rebooted (Ctrl+Alt+Del) so that the installed driver and the modified S/VGA settings (if any) have taken effect.

The following instructions are intended to be used while operating the PC; pictures of the S/VGA are intentionally not shown, in favor of focusing the reader's attention on the real S/VGA screen.

4.1. Start XCAP

Start XCAP by clicking: 

    Start (on the Windows Taskbar)
    XCAP Imaging
and then clicking: 
    XCAP for Windows

The XCAP Main Window now appears.

4.2. Open PIXCI Imaging Board

In the XCAP Main Window, click: 

    PIXCI
    PIXCI Open/Close
A pop-up window appears.

Clicking: 

    Open
opens the PIXCI imaging board for use, removes the Open/Close pop-up window, creates a PIXCI Image Viewer window showing the first PIXCI frame buffer, creates an Adjust window with commonly used video capture adjustments, and creates a Shortcuts Toolbar for accessing the most commonly needed features.

The following windows are now active:

  1. The Main Window, which has options for reconfiguring the PIXCI imaging board, and features independent of the PIXCI imaging board, such as loading images into image buffers unrelated to video capture hardware.
  2. The PIXCI® Image Viewer window, from which the PIXCI® frame buffers are captured, viewed, examined, processed, measured, and saved, with a status bar below the image where cursor coordinates and other information is displayed.
  3. The PIXCI® Shortcut Toolbar, with shortcuts for the most commonly needed features relating to the PIXCI® imaging board and its frame buffers.
  4. An Adjust window, with commonly used video capture adjustments.

If XCAP has already been installed, it may have been configured with one or more variations, such as, (a) Eliminate the Main Window, automatically opening and displaying the PIXCI® Image Viewer, (b) Configure the Shortcuts and/or Adjust features to be attached to the The PIXCI® Image Viewer window, rather than detached into their own windows, (c) Select whether the Shortcuts and/or Adjust features appear automatically, or only when 

    Capture
    Adjustments
or 
    Capture
    Shortcuts
are clicked, or (d) Remove the status bar, increasing the screen area available for image display. These variations allow custom configuration of XCAP, but don't affect the functionality of the Shortcuts or Adjustments features.

4.3. PIXCI® SV2, SV3, SV4, SV5 Video Configuration

The PIXCI® SV2, SV3, SV4, and SV5 default to the NTSC video format for S-Video, using the S-Video input, capturing full video resolution. These defaults can be adjusted as follows.

4.3.1. Video Format

From the Main window, click: 

    PIXCI®
    PIXCI® Video Setup
    Format
Select an alternate video format, and click: 
    OK

4.3.2. Video Resolution

Reducing the video resolution (the number of pixels captured per line and column) allows capturing more video frames in a given size of frame buffer memory.

From the Main Window, click: 

    PIXCI®
    PIXCI® Video Setup
    Resolution
Modify: 
    Data Pixels per Line
    Data Lines per Field


    Frame Buffer: 2 Fields      (i.e. interlace)
    Frame Buffer: 1 Field
as per your application's needs. The: 
    Image Buffers in Memory
shows the number of frame buffers available with the current selections. Click: 
    OK

4.3.3. Input Selection

To select one of the video input connectors on the imaging board's bracket, from the PIXCI® Image Viewer, click: 

    Capture
    Adjustments
The video input connector may be selected numerically with: 
    Video Input (0 is the top most connector, 1 the next)
Alternately, a specific connector on the picture of the imaging board's bracket may be clicked.

4.3.4. Saving the Video Configuration

The selections under the Main Window: 

    PIXCI® Video Setup
and under the PIXCI® Image Viewer: 
    Adjustments
are automatically saved when the PIXCI® imaging board is closed, or XCAP is exited. When the PIXCI® imaging board is next opened (from the XCAP Main Window clicking): 
    PIXCI
    PIXCI Open/Close
    Camera & Format
You may choose: 
    Open w. last used Video Setup
to use the previous video setup, or choose: 
    Open w. default Video Setup
to start anew with the default video format, resolution, and video input.

4.4. Capturing Images

Once the PIXCI® imaging board is opened for use, images may be captured from the PIXCI® Image Viewer, clicking: 

    Capture
    Snap
or 
    Capture
    Live
The Snap captures a single image into the current frame buffer, while Live continuously captures images into the current frame buffer, continuously updating the image shown on the S/VGA.

The Live mode may be used to adjust the camera's focus, aperture, and position. The Live mode may be halted by clicking: 

    Capture
    UnLive
A Live followed immediately by Unlive has the same effect as Snap.

If the current video resolution and frame buffer memory size allows more than one frame buffer, clicking: 

    Capture
    Adjustments
provides the: 
    Current Frame Buffer:   0
or sometimes shortened to: 
    Current Buffer:   0
which may be incremented or decremented at any time, whether in Live or UnLive mode. The window reached by clicking: 
    Capture
    Adjustments
has convenient buttons which duplicate the Snap, Live, and UnLive features.

As three of the most commonly used operations, the Snap, Live, and UnLive are also available in the Shortcuts Toolbar, in the top row, at the fifth and sixth from the left. The Shortcuts also allow changing the current frame buffer; in the top row, the four icons at the left switch to the first frame buffer, the next frame buffer (e.g. current buffer +1), the previous frame buffer (e.g. current buffer -1), and the last frame buffer, respectively.

4.5. Examining Images

4.5.1. Altering How the Image is Displayed

The PIXCI Image Viewer can be moved and resized, using standard Windows techniques (drag the window's title bar, drag the window's corner, etc). By default, the captured image is displayed with resizing, so that the entire image fits within the Image Viewer.

For many engineering applications, examination of individual pixel values is critically important. Resizing the image may ''hide'' defective pixels; resizing an image with interlace jitter may turn odd/even line striping into bars of striping.

To view the exact pixels, from the PIXCI® Image Viewer, click: 

    View
    Display
    Resize: None (1 to 1)
Each image pixel is now displayed as exactly one S/VGA pixel. Of course, depending upon the image resolution, S/VGA resolution, and window size, the entire image may not fit. If the image doesn't fit, then (a) Scroll bars appear, allowing the viewed portion of the image to be panned and scrolled throughout the entire image, and (b) Moving the mouse with right button held over the displayed image causes panning or scrolling (if there is more image to be seen in the direction the mouse is moving).

Note that when: 

    Resize: None (1 to 1)
is selected, the displayed image's aspect ratio may not appear correct; the aspect ratio can't be corrected without some form of resizing or resampling!

4.5.2. Zoom

To magnify the image, from the PIXCI® Image Viewer, click: 

    View
    Zoom, Pan, Scroll
    Zoom On
The magnification factor can be adjusted with: 
    Zoom Ratio
When magnified, only a portion of the image is visible. As described above, the viewed portion may be panned and scrolled through the entire image with the scroll bars, or by moving the mouse over the image with right button held.

4.5.3. Numeric Pixel Values

To examine numeric values of pixels as a table, from the PIXCI® Image Viewer, click: 

    Examine
    Pixel Peek
A table of pixel values for a portion of the image appears, showing pixel values in the neighborhood of the displayed X and Y coordinates. The portion of the image numerically displayed can be moved by using the scroll bars, or by entering new X and Y coordinates.

The portion of the image which is numerically displayed can also be moved interactively by clicking: 

    Coord<=>Cursor
A cursor now appears over the image window (the Pixel Peek window may have to be moved to the side so that both the pixel peek window and the image viewer window can be seen); clicking the mouse on the image viewer window moves the cursor to that position, and repositions the numerically displayed portion of the image to be centered at that position.

To examine pixel values as a two dimensional graph, click: 

    Examine
    Pixel Plot
and 
    Controls
    Where
and Plot Row
or  Plot Column
A graph of pixel values for a line (column) of the image appears, showing pixel values along the line (column) at the displayed Y (X) coordinate. The line (column) of the image which is shown can be moved interactively by clicking: 
    Coord<=>Cursor
A cursor now appears over the image window; clicking the mouse on the image window moves the cursor to that position, and repositions the displayed line (column) to that Y (X) coordinate.

4.6. Saving Images

To save an image, from the PIXCI Image Viewer, click: 

    File
    Save Image
Choose a file format, such as: 
    TIFF
    JPEG/JFIF
    BMP
    PCX
    Targa (TGA)
    X/Y Binary
    X/Y ASCII
TIFF is an industry standard, and the most commonly used image file format; TIFF is suggested for saving and reloading an image into XCAP, and suggested for exporting images to other programs which support TIFF. The JPGE/JFIF is also a commonly used image file format and provides high, but lossy, compression. The BMP, PCX, and TGA formats are useful when exporting an image into other programs that don't support TIFF; but these file formats support only 8 bits per pixel component (such as 8 bit monochrome or 24 bit RGB). The X/Y Binary and X/Y ASCII export raw pixels, left to right, top to bottom, with no excess information such as dimensions, bit depth, date, format, etc; these are useful for exporting images to a spreadsheet (X/Y ASCII), or to your own program that can assume the image's dimensions and can simply read a 2-D array of values.

After selecting a file format, enter a file name: 

    File Name:  xx.tif
and click 
    OK
to save the image. Or, use the: 
    Browse
button to access the standard Windows File Dialog, click 
    Accept
to accept the filename selected by browsing, and click 
    OK
to save the image.

5. XCAP Software Guide

XCAP is a family of sophisticated, interactive, imaging programs specifically designed to support the PIXCI series of imaging boards, but also able to process and analyze images from other imaging sources. Several versions of XCAP are available: XCAP-Std, XCAP-Plus, XCAP-Lite, and XCAP-Demo. All versions share the same user interface and menu structure, but selected features in XCAP-Std, XCAP-Lite, and XCAP-Demo are not operational. XCAP is distributed on CD, diskette(s), or downloadable from the EPIX, Inc. website. After installation, a 12 character identification code[5] is entered to configure XCAP as either XCAP-Std, XCAP-Plus,[6], or XCAP-Lite; or, lacking a valid code, configured as XCAP-Demo to browse, but not use, XCAP's features.

XCAP-Std is an interactive, imaging program designed for scientific, industrial, and machine vision applications. XCAP-Std supports the PIXCI imaging board, providing video format and resolution configuration; continuous (live), video rate sequence, and triggered capture; and single or sequence, zoomed or resized, display. The image frame buffers of PIXCI imaging boards can be loaded, examined, processed, analyzed, measured, printed, annotated, and saved.

XCAP-Std also allows loading and analyzing a pre-existing image or image sequence with size, pixel depth, and color space independent of the PIXCI imaging board's configuration; XCAP-Std can be used with pre-existing images even when the PIXCI imaging board is not present. XCAP-Std can also acquire images from TWAIN compliant devices.

XCAP-Plus provides extra, advanced, features in addition to all of the capabilities of the XCAP-Std, such as support for specialized, optional, hardware.

XCAP-Lite is a basic version of XCAP-Std. XCAP-Lite provides similar image acquisition and PIXCI imaging board control capabilities, video format and resolution configuration; continuous (live), video rate sequence, and triggered capture; and single or sequence, zoomed or resized, display. XCAP-Lite also provides some of the image loading, examining, printing, and saving features, but minimal processing, measurement, analysis, and scripting features are functional. XCAP-Lite can also be used with pre-existing images, but only while the PIXCI imaging board is present and opened for use.

XCAP-Demo allows browsing through the dozens of processing, measurement, analysis, and graphics features provided in XCAP-Plus, XCAP-Std, or XCAP-Lite. Images can't be loaded from, or saved to, files. Nor can the PIXCI imaging board be operated with the XCAP-Demo version.

As XCAP-Plus, XCAP-Std, and XCAP-Lite share many common features, this manual typically refers to all versions as XCAP, except where explicitly differentiated.

The XCAP programs are organized into two major types of windows, the Image Viewer Window and the Main Window.

For each image, or sequence of images, an Image Viewer Window shows that image, or a selected image of that sequence, and via its menu bar allows viewing, examining, processing, analyzing, or drawing upon that image (sequence). The Image Viewer Window associated with the PIXCI imaging board's frame buffers also provides features for capturing new images. There can be multiple Image Viewer Windows for the same image (sequence), allowing, for example, viewing the image both zoomed and unzoomed, or simultaneous viewing of different images of a sequence.

The Main Window allows creating new image (sequences), and thus new Image Viewer Windows, either by loading a new image from file, explicit specification of the new image's dimensions, or by opening the PIXCI imaging board for use. Video setup for the PIXCI imaging board, such as modifying the video resolution or color space, are also in the Main Window; these features destroy and re-create the PIXCI imaging board's Image Viewer Window. The Main Window also provides features not directly associated with an image (sequence), such as scripts, RS-232 device control, and features to customize XCAP.

5.1. The Main Window

The XCAP main window provides a menu bar with File, Images, Scripts, Utility, PIXCI®, and Help features.

5.1.1. Main Window - File

The main window's File allows loading of pre-existing images into new image buffers, displaying attributes about pre-existing images, and acquiring images from TWAIN compliant devices.

The Load New Image and Load New Image Sequence creates a new image buffer (sequence) with dimensions, pixel depth, and color space matching a specified TIFF, BMP, or multimedia format file(s), and loads the image(s) from the file(s). This feature, and the image buffer (sequence) created, is unrelated to the PIXCI imaging board's frame buffers. After creation and loading, the new image (sequence) is displayed, processed, and analyzed in The Image Viewer Window, described below. The Load New Image can also load images directly from an Internet URL. The XCAP-Lite version does not provide the Load New Image Sequence or loading directly from an URL features.

The Image File Info displays information about a specified TIFF or BMP format file without loading the image. The information displayed includes the image's dimensions, pixel depth, color space, palette option, and other file format specific information.

The TWAIN Select Source and TWAIN New Acquire allow using XCAP as a TWAIN Application, acquiring images from TWAIN compliant imaging devices (TWAIN Sources). The TWAIN Select Source allows selecting which TWAIN Source is to be used, and the TWAIN New Acquire allows acquiring one image from the TWAIN Source. The XCAP-Lite version does not support being used as a TWAIN Application.

The Window List displays a list of active windows belonging to XCAP; selecting a window causes that window to appear, if previously hidden, and/or to appear over other windows (subject to the priority of selected windows to always appear ''on top'').

5.1.2. Main Window - Images

The main window's Images allows creating new image buffers and activating any existing image windows that may not be on-screen.

The New Image creates a new image buffer, or sequence of image buffers, with specified dimensions, pixel depth, color space, and palette. This feature, and the image buffer created, is unrelated to the PIXCI imaging board's frame buffers. After creation, the new image is displayed in an The Image Viewer Window, as described below.

Underneath New Image are listed all existing image windows, whether for PIXCI imaging board frame buffers, or for independent image buffers. (The image window for PIXCI imaging board frame buffers appears only after the PIXCI imaging board has been opened for use, see below). An image window which has been closed and thereby off-screen can be reactivated by clicking the image window's name.

5.1.3. Main Window - Scripts

The main window's Scripts provides features for recording and playing scripts. A script recording contains most of the user's interactions with the windows of XCAP; playing the script duplicates the original actions.

Some user actions are not recorded. Using the mouse to drag the cursor or other graphic across an image is not recorded as these actions are highly dependent upon image content (such as the typical scenario of dragging the cursor until it is positioned next to an artifact in a captured image), would likely be inappropriate to other captured images, and would consume a significant amount of disk space. Instead, after positioning the cursor interactively the user can record the final position by clicking the appropriate numeric cursor coordinates. Features activated with keys, or clicking icons are not currently recorded; such features can also activated by other means, which are recorded.

A recorded script is in a human readable form and can be altered with any common editor capable of handling ASCII text, allowing scripts to be modified or combined. A selected script may be executed automatically after XCAP starts, this feature is set in Utility, Program Setup, Startup Script.

The Load Tool Bar provides one or more user-defined tool bars of shortcuts, each shortcut represented by an icon which, when clicked, executes a user-specified script. Each shortcut may also specify an optional keyboard key which, when pressed, also executes the user-specified script.

The Script Remote Control allows using XCAP as a hidden, off-screen, ''black box''; any end-user application that can manipulate text files, can also remotely control XCAP.

The XCAP-Lite version does not support recording scripts, creating user-defined tool bars, or the remote control feature. The XCAP-Lite version can play scripts previously created with XCAP.

5.1.4. Main Window - Utility

The main window's Utility provides an assortment of features which are of secondary importance; features which allow fine tuning of XCAP, or features needed in relatively few circumstances.

The Black Board allows customizing XCAP, creating non-procedural programs, and collecting data. The black board allows inter-connecting the numeric and text field of other windows; computed results, such as center-of-mass, may be written onto the black board - parameters for other features, such as the coordinates of a displayed grid, may be extracted from the black board - combining these automatically repositions the grid as the center of mass is recomputed! Other features allow computed values (similar to a spreadsheet), ''push''ing buttons, timed updates, creating a report to file or an RS-232 port, collecting data, and graphing the black board's contents. The XCAP-Lite version allows use of the Black Board for computing values (similar to a spreadsheet), but does not allow inter-connections with other features or creating reports or graphs.

A Message Log window lists warnings and errors that arise from performing various operations. By default, the message log window appears automatically when a message is added, and disappears a few seconds later. Auto appearance, auto hide, and audible clicks can be disabled (from the message log window's menu bar). The menu-bar's Message Log allows explicit activation of the message log window.

The Program Setup shows information about the installed XCAP components, such as their revision level, and sets various configuration options. For versions of XCAP which require an authorization key, it also shows the ID of the key required by the instant copy of XCAP.

The Program Setup allows specifying the name of a script to be executed when XCAP starts, whether warning pop-up windows (if any) are to be shown, whether previously saved settings are to be loaded, and other similar initial or terminal conditions.

The Program Setup also enables user-defined translation of XCAP labels and messages for use in non-English speaking countries. The XCAP-Lite version does not support creating user-defined translated labels and messages, but may use translated labels and messages previously created with XCAP.

The Windows Info displays information about the current Windows environment, such as memory usage and the S/VGA display adapter's features, as reported by Windows. The Java Info displays information about the status of Java, under which XCAP runs. Both of these features are primarily of use in resolving questions submitted to EPIX, Inc. Technical Support.

The Window Style allows setting some characteristics of XCAP windows, such as color or character size and font. Some characteristics of window style are instead controlled by the Windows Control Panel.

The Audio Clip allows recording and playing short audio ''clips''.

The RS-232 Control allows ''raw'' communication with a camera or other device connected via the computer's RS-232 port. The RS-232 Control is designed specifically for device control, including options to communicate with byte values, rather than as a common ''terminal emulator''. XCAP may also provide more convenient, camera-specific ''smart'' controls, provided after a camera-specific imaging board is opened, via the Capture - Adjustments.

The I/O Port Peek & Poke allows controlling arbitrary devices accessible via I/O port peeks and pokes. This feature must be used with caution; peeking or poking arbitrary ports will cause computer malfunction! This feature is not available under Windows NT.

The Screen Capture allows capturing the current S/VGA screen graphics, saving the graphics to a file, or printing the graphics. The Screen Capture also allows capturing numeric and textual parameters into a text file, suitable for loading into a spreadsheet or other programs. The XCAP-Lite version does not support screen capture.

The Volpi intralux dc-1100 and Illumination Technologies 3900 provide support for controlling these light sources through their RS-232 ports.

5.1.5. Main Window - PIXCI®

The main window's PIXCI® allows initiating access to the PIXCI imaging board and provides configuration options. Actual operation of the PIXCI imaging board is performed through the PIXCI image viewer window's menu-bar.

The PIXCI® Open/Close allows opening access to, or closing access to, the PIXCI imaging board. Once open, the model (and submodel, as appropriate) of the PIXCI imaging board is available via the Board Info button. After opening, the contents of the PIXCI image board's frame buffer(s) are displayed in The Image Viewer Window, along with a tool bar of PIXCI® Image Viewer - Capture - Shortcuts and a status bar of PIXCI® Image Viewer - View - Status Bar are shown as described below.

The PIXCI® Video Setup allows configuring the video format, video resolution and other, model specific, video characteristics. For example, for PIXCI SV2, SV3, SV4, and SV5 models, the PIXCI® Video Setup allows selecting NTSC, RS-170, S-VIDEO, CCIR, or PAL, allows selecting the video window size and capture resolution, and selecting other video acquisition characteristics. For other models, such as the PIXCI® D, fewer options may be provided, as the PIXCI® D models are camera specific.

The current video setup is automatically saved when access to the PIXCI imaging board is closed, and reloaded when the PIXCI image board is later opened. The PIXCI® Save Video Setup and PIXCI® Load Video Setup may be used to explicitly save or reload the current video setup, such as to choose amongst several favorite setups, or to export the current video setup to the XCIP program or the XCOBJ library.

The PIXCI® Status shows the PIXCI imaging board's current status, such as the state of the TTL trigger input(s) and output(s), the number of elapsed video fields, the board's model and submodel, and configured image memory size.

The PIXCI® Serial Peek & Poke allows ''raw'' communication with a camera connected to the serial port on selected models of the PIXCI® imaging board. XCAP may also provide more convenient, camera-specific ''smart'' controls, provided after a camera-specific imaging board is opened, via the Capture - Adjustments.

The PIXCI® Connections provides, as appropriate for the specific model of PIXCI imaging board, a map of the board's connections, connectors, option jumpers, and adjustments.

The PIXCI® Camera Info provides a list of cameras and video formats supported by XCAP and various PIXCI® imaging boards. The PIXCI® Camera Info also allows viewing a non-operational Capture - Adjustments window (i.e. the ''Control Panel'', which provides integrated control of both imaging board and any supported camera).

The PIXCI® TWAIN Sourcery allows using XCAP, in conjunction with the ''XCAP Sourcery'' TWAIN driver, as a component of a ''smart'' TWAIN Source, allowing other applications to capture images from the PIXCI® imaging board, while XCAP provides imaging board, camera controls, and, optionally, image preprocessing.[7] (The XCAP-Lite version does not provide image preprocessing). The PIXCI® TWAIN Sourcery should not be confused with TWAIN New Acquire; the former allows XCAP to provide image data to other, TWAIN compliant applications; the latter allows XCAP to accept image data from other TWAIN compliant sources. The TWAIN New Acquire should never be used to attempt to acquire image data from the PIXCI® TWAIN Sourcery!

The PIXCI® Image-Pro Sourcery allows using XCAP, in conjunction with the ''XCAP Sourcery'' Image-Pro driver, as a component of a ''smart'' video source, allowing Image-Pro to capture images from the PIXCI® imaging board, while XCAP provides imaging board, camera controls, and, optionally, image preprocessing.[8]

5.2. The Image Viewer Window

Each image buffer (sequence), or frame buffer (sequence), is displayed in an image viewer window, which is the focus of activity for examining, processing, or analyzing that image buffer (sequence). The image viewer window provides a menu bar with File, View, Examine, Modify, Measure, Draw, AOI, and Help features. The image viewer window associated with the PIXCI imaging board's frame buffer(s) also provides a Capture feature.

5.2.1. Image Viewer - File

The image viewer window's File allows saving, loading, or printing the image, shows information about the image's dimensions, pixel depth and color space, and allows closing the image viewer window.

The Load Image and Save Image allow saving or loading the image in a variety of file formats. The Load Image, unlike the Load New Image described above, loads an image file into the current image buffer, resizing and/or color converting to fit the image buffer's existing dimensions, pixel depth, and color space. The Load Image can also load images directly from an Internet URL. The XCAP-Lite version does not support loading images directly from an Internet URL.

For image viewer windows associated with an image buffer sequence, the Save Image Sequence and Load Image Sequence allow saving or loading multiple images of the sequence as a numbered sequence of image files, or as a single TIFF or AVI format image file with multiple images. The XCAP-Lite version does not support loading or saving of image buffer sequences in a single operation; however multiple uses of Load Image or Save Image can load or save each image buffer of a sequence.

The E-Mail Image allows directly e-mail'ing the image, in a variety of file formats, from within XCAP. The XCAP-Lite version does not support the E-Mail Image feature.

The Print, Windows and Print, PXIPL allow printing the image; the former printing via Windows and supporting a wide variety of printers, the latter printing via the PXIPL library and supporting only the most popular printers, but providing precise control of print options. The XCAP-Lite version does not allow printing via the PXIPL library.

The Attributes shows the image's (or image sequence's) dimensions, pixel depth, and color space.

The Duplicate Image allows creating a new image buffer, and copying the image, in one step. It optionally allows copying the image's current appearance, as modified by the palette and graphics, instead of the underlying image. The XCAP-Lite version does not provide Duplicate Image.

The Copy to Black Board allows copying the image's pixel values into the Black Board. The XCAP-Lite version does not provide Copy to Black Board.

The Close Viewer closes the window, but does not destroy the image (sequence). The Close & Dispose of Image closes the window and destroys the image (sequence). The image viewer window associated with the PIXCI imaging board's frame buffer(s) does not provide a Close & Dispose of Image; an image viewer window is available whenever the PIXCI imaging board is open for use.

5.2.2. Image Viewer - View

The image viewer window's View provides options governing the appearance of the displayed image.

The Shortcuts allows activating or deactivating a tool bar of icons providing shortcuts for accessing often used features, and is described under Image Viewer - View - Shortcuts.

The Status Bar allows activating or deactivating a small status bar with current information, and is described under Image Viewer - View - Status Bar.

For image viewer windows associated with the PIXCI image board's frame buffer(s), the Adjustments allows setting common adjustments, as suitable for the model of the PIXCI imaging board in use, and is described under PIXCI® Image Viewer - Capture.

The Full Screen allows displaying the image in the full S/VGA screen, with little or no window ''frame'' around the image. A mouse click, anywhere on the S/VGA, restores the previous mode. The XCAP-Lite version does not provide the Full Screen feature.

The Always-On-Top allows forcing the image viewer window, and its subwindows, to always be ''above'' other windows; subject to the other windows' also requesting Always-On-Top, and the whims of the host operating system. This option is typically useful only when XCAP is being used in combination with other applications, such as in conjunction with the PIXCI® TWAIN Sourcery or PIXCI® Image-Pro Sourcery feature.

The Refresh forces the displayed image to be redrawn once; normally manual refresh is not needed, but occasionally, when the image was (partly) covered and uncovered by other window(s), the displayed image might ''forget'' to be updated.

For images composed of index pixels and palette, the Image's Palette allows manipulating the image's attached palette; for images of other types, the Image's Palette is not selectable. For all images, the Viewer's Palette allows manipulating a palette which is not attached to the image. Either can be used for contrast enhancement, adjustment of black level and gain, or, for monochrome images, false coloring. Either, or neither, of the palettes can be selected for use under Misc Options.

For image sequences, the Sequence Play allows ''playing'' the sequence, image by image, at a selected rate. The Sequence Thumbnails shows a window in which each image of the sequence is a small ''snapshot''; clicking a snapshot selects that image for display by the image viewer window. The XCAP-Lite version does not provide the Sequence Thumbnails.

The Cursor allows activating a cursor over the image, which may be positioned via coordinates, or by clicking the mouse on an image feature.

The Display allows selecting how the image is displayed: (a) No resizing so that there is a one to one relationship between an image pixel and a displayed S/VGA pixel and is quickest, although the entire image may not fit within the window and must therefore be panned and scrolled, (b) Resize by nearest neighbor which is relatively quick, or (c) Resize by bilinear interpolation which may produce better results for continuous tone images, but is slower. For the resize modes, the aspect ratio can also be modified. For the image viewer window associated with the PIXCI imaging board's frame buffer(s), the Display provides additional features, identical to the Live Options described below.

The Zoom, Pan, Scroll allows magnifying the displayed image, and panning and scrolling to view different portions of the image under magnification. For image sequences, a specific image of the sequence can be selected for display. In addition to panning and scrolling via explicit coordinates and via scrollbars, holding the right mouse button and moving the mouse over the image also implements panning and scrolling.

The Misc Options allows selecting which palette, if any, is to be used during display and during file loads and saves. An option to display only even lines, or only odd image lines, allows avoiding interlace artifacts during display.

Each image buffer (sequence) may have several simultaneously active viewers, allowing, for example, viewing the same image buffer both magnified and unmagnified. The Launch 2nd Viewer creates a second image viewer window into the same image buffer (sequence), with the same features as the original image viewer window. The XCAP-Lite version does not provide the Launch 2nd Viewer feature.

5.2.3. Image Viewer - Examine

The image viewer window's Examine provides options to examine the image.

The Pixel Peek allows numeric display of the pixel values in the vicinity of the image cursor.

The Pixel Peek & Poke allows numeric display and modification of the pixel value at the image cursor.

The Pixel Plot displays a two dimensional graph of pixels values along a selected image line or column, all image lines, or for image sequences, a vector. Features attached to the graph show specific pixel values and descriptive statistics such as lowest value, highest value, mean value, and standard deviation. The XCAP-Lite version does not provide a graph of all image lines, and does not provide descriptive statistics.

The Pixel Plot 3D displays a three dimensional graph projection of the image.

The SMPTE VITC allows searching the image for valid SMPTE Vertical Interval Time Codes and displaying the decoded codes.

The XCAP-Lite version does not provide the SMPTE VITC features.

5.2.4. Image Viewer - Modify

The image viewer window's Modify provides image processing operations which modify the image, modify each image (independently) in a sequence (typically named ''Sequence ...'') or modify one or more images in a sequence by combining data from across multiple images (typically named ''... Sequence ).''

The Patterns draws various test patterns in the image. The Sequence Patterns does the same on each image of a sequence.

The Set sets image pixels to a specified value. The Sequence Set does the same on each image of a sequence.

The Arithmetic provides pixel arithmetic, such as adding a constant value. The Sequence Arithmetic does the same on each image of a sequence. The Src+Dst Arithmetic does the same with distinct source and destination images.

The Binning provides averaging or integrating pixel values in ''bins'' of a checkerboard. The Sequence Binning does the same on each image of a sequence. The Src+Dst Binning does the same with distinct source and destination images.

The Contrast Modification allows modifying the image's contrast. The Sequence Contrast Modification does the same on each image of a sequence. The Src+Dst Contrast Modification does the same with distinct source and destination images.

The Convolution allows convolving the image with user-defined kernels. The Sequence Convolution does the same on each image of a sequence. The Src+Dst Convolution does the same with distinct source and destination images.

The Correlation Map allows correlating, or matching, a kernel image over a larger image, resulting in a profile image whose intensity, at each location, varies in proportion to the degree of match, at that location. The Sequence Correlation Map does the same on each image of a sequence. The Src+Dst Correlation Map does the same with distinct source and destination images.

The Edge Detection provides Kirsch, Sobel, and other standard edge detectors. The Sequence Edge Detection does the same on each image of a sequence. The Src+Dst Edge Detection does the same with distinct source and destination images.

The FFT provides Fast Fourier Transforms and Discrete Fourier Transforms. The Sequence FFT does the same on each image of a sequence. The Src+Dst FFT does the same with distinct source and destination images.

The Interlace & Flicker provides line and pixel shuffling operations. The Sequence Interlace & Flicker does the same on each image of a sequence. The Src+Dst Interlace & Flicker does the same with distinct source and destination images.

The Morphology provides morphological operations with user-defined kernels. The Sequence Morphology does the same on each image of a sequence. The Src+Dst Morphology does the same with distinct source and destination images.

The Noise Generator allows adding pseudo-random noise with uniform and other distributions to an image. The Sequence Noise Generator does the same on each image of a sequence. The Src+Dst Noise Generator does the same with distinct source and destination images.

The Normalization provides single image normalizations. The Sequence Normalization does the same on each image of a sequence. The Src+Dst Normalization does the same with distinct source and destination images.

The Rotation & Shift provides image rotations and shifts. The Sequence Rotation & Shift does the same on each image of a sequence. The Src+Dst Rotation & Shift does the same with distinct source and destination images.

The Spatial Filtering provides low pass, high pass, and other filters. The Sequence Spatial Filtering
