SENSOR BY MICRON - The SILICON VIDEO 9T001C camera is based on the MT9T001 CMOS sensor from Micron. This progressive scan sensor offers an electronic shutter with Global Reset Release, continuous and single frame capture, windowing, column and row skip modes, snapshot mode, 10 bit dynamic range, and an active programmable array resolution of 2048H x 1536V pixels.

ASYNCHRONOUS CAPTURE with STROBE OUTPUT -
The SV9T001C camera offers Asynchronous Capture: the recording of an image (or images) in response to a trigger signal. The camera also provides a strobe output signal to synchronize an electronic flash (strobe), for bright, uniform, short duration illumination. The SV9T001C can be triggered to capture an image (or images) as might be required in product inspection, laser beam profiling, medical imaging, or any application that requires image capture at a specific time (there is a delay of one frame time between trigger and start of frame capture). The optional use of strobe illumination allows minimum exposure time with maximum image sharpness.

ONLY ONE CABLE - A single cable connects the SILICON VIDEO 9T001C camera head to the PIXCI SI board. The PIXCI SI board provides power to the camera, sends and receives camera control signals, generates the programmable pixel clock, and receives video data. No dedicated power supply or power cable required.Multiple cabling options are available, see the SILICON® VIDEO Cable page for more details.

CAPTURE & ADJUST DIALOG - The XCAP Imaging Application provides a Capture & Adjust Dialog for selecting pixel clock frequency, integration/exposure time, capture resolution, gain, offset, trigger control, and more. The camera dialog provides automatic white balance as well as manual adjustment of Red, Green, and Blue gain.

The SILICON VIDEO 9T001C camera system includes:

• 3 Megapixel Color Camera Head
• Infrared Cut Filter
• Shielded Interface Cable (various lengths)
• PIXCI SI PCI Image Capture Board
• XCAP-Lite Imaging Program (XCAP-Ltd or Std Optional)

PIXCI® SI4 – A single PCI Express x4 board supporting up to four SILICON VIDEO® cameras is also available. The cameras may be the same or a mix and can operate simultaneously or independently. The PIXCI® SI4 can have four cameras expose simultaneously from one trigger or can use four trigger inputs – one for each camera.

To complete a SILICON VIDEO® 9T001 system add 1/2" format C-Mount lens, analysis software, lighting, and computer - all available from EPIX, Inc., or an authorized distributor of EPIX® imaging products.

Example of SV9T001C Capture & Adjust Dialog.

SV9T001C Capture & Adjust Dialogs

The XCAP Imaging Program simplifies camera operation with a dedicated Capture & Adjust Dialog. The Capture & Adjust Dialog provides one convenient location for camera controls such as exposure, resolution, triggering, color balance and frame rate. In addition, the SV9T001C Dialog provides a camera-to-computer communication indicator, a programmable pixel clock, and exposure synchronized to AC power frequencies.

The Color & White Balance menu offers simple color balance settings for common sunlight, fluorescent light, and incandescent light conditions. In addition, for greater color precision, or for unusual light sources, XCAP offers advanced options for building custom color settings.

The camera's pixel clock frequency is user-selectable over a range of 25 MHz to
70 MHz. The programmable pixel clock provides a wider range of frame rates and exposure times.

The intensity of AC lighting fluctuates with the phase of the AC voltage that powers it. Capturing sequences of images using arbitrary frame rates with AC lighting will result in images with differing brightness. The SV9T001C Capture & Adjust Dialog offers a convenient fix for this problem — exposure times can be easily set to multiples of the local AC line frequency, either
1/50^th or 1/60^th second. Synchronizing exposure times to the line voltage provides images with consistent illumination from a varying-intensity AC light source.

The presence or absence of the 2 lines between the camera and computer icons indicate whether or not the computer and camera are properly connected and capable of communicating.

Video-To-Disk Capture

The optional XCAP-Std imaging program enables video-to-disk capture, potentially for several hours. Requires a host computer with two 7200 rpm hard drives configured as RAID 0. EPIX® offers complete imaging systems, designed to your specifications, guaranteed to capture uncompressed video to disk without dropping frames.

FAQ

What is included in the price of the SILICON VIDEO® 9T001C camera?

The $1095.00 price includes the camera head with adjustable ‘C’ lens mount, infrared cut filter, ¼-20 tripod mount, 7 foot cable, PIXCI® SI PCI bus frame grabber, and the XCAP-Lite imaging program.  A lens is optional.  A longer cable is optional (maximum cable length is 50 feet or 15 meters, but at a 70 MHz pixel clock rate a 14 foot cable is the longest recommended).   A complete imaging system, including computer with RAID array, is optional.

What is an Infrared (IR) Cut Filter and why do I need it?

The SV9T001C camera uses a CMOS sensor. Lack of an IR cut filter in the presence of IR illumination produces an image with reduced contrast because IR activates all pixels of all colors; the red, green, and blue filters on the sensor’s pixels are almost transparent to IR which results in near-equal charge accumulation from IR illumination in all pixels. The SILICON VIDEO 9T001C includes a lens mount with an IR cut filter to attenuate the infrared sensitivity and provide better color balance. The IR cut filter is attached to the rear of the adjustable lens mount -- just in front of the sensor. As a result, the IR cut filter is always in place and protects the sensor from contamination when lenses are interchanged.

If IR sensitivity is important, or if other filters will be used on the lens, then order the optional SV9T001-OPT-MNTNOF ($25.00) lens mount without the IR cut filter.  With 2 lens mounts – one with filter and one without – you can easily optimize the camera for best color balance or infrared sensitivity.

What are the capabilities of the included XCAP-Lite imaging program and would I be interested in a more advanced version of the software?

There are different versions of the XCAP program. Please visit http://www.epixinc.com/products/xcap.htm. XCAP-Lite will capture into a maximum of 64 MB of computer memory – which limits image capture to just a couple of seconds. XCAP-Ltd allows capture to the limit of computer memory – but does not support capture to hard disk.

Neither the XCAP-Lite nor the XCAP-Ltd versions support video capture to hard disk, which is the only means for achieving video rate capture for an extended time period.

If the goal is to capture a video clip with duration greater than 90 seconds, then the $1495.00 XCAP-Std is required.    The XCAP-Std program will capture video to disk from the SV9T001C camera installed in a computer with two 7200 rpm hard disks in a RAID 0 configuration.

Explain Video Capture to RAID Array from the SILICON VIDEO® 9T001C camera (using the XCAP-Std imaging program).

The SILICON VIDEO 9T001C camera streams raw Bayer Pattern color data to hard disk at video rate. Image data is not compressed. At the end of a video session, the hard disks hold raw color data in an efficient EPIX-proprietary VIF video format. Assuming the camera is operated in 8-bit mode, each pixel is stored as 1 byte (256 intensity levels) of Red, Green, or Blue. Conversion to an industry standard format such as TIFF, BMP, AVI or JPEG requires a subsequent processing and conversion step. The image data on hard disk must be reloaded into the computer at which time the raw data is converted into RGB color -- and then stored in any of the following industry-standard formats:

• One TIFF w. Sequence
• One AVI 1.0 w. Sequence
• One AVI 2.0 w. Sequence
• One X/Y Binary w. Sequence
• Sequence of TIFF’s
• Sequence of JPEG/JFIF’s
• Sequence of BMP’s
• Sequence of FITS’s
• Sequence of X/Y Binary’s
• Sequence of X/Y ASCII’s

Conversion from the VIF format to a standard format requires more time than is required to capture the video rate (original or primary) sequence. The efficient VIF video format is required for primary capture because industry standard video formats [non-compressed] are not efficient enough [not fast enough] to allow video rate capture direct to RAID array.

130 Gigabytes of hard disk capacity are required for 1 hour of raw Bayer Pattern sequence capture in the VIF format when the SV9T001C camera is used with a 48 MHz pixel clock and with Bit Depth set to 8 Bits per pixel.  The conversion to RGB color requires 3 times as much storage space or approximately 390 Gigabytes.  Plan on using approximately 520 Gigabytes [130 GB x 4 = 520 GB] of hard disk capacity for both the raw Bayer data as well as the converted industry-standard sequence.  After the conversion process has been completed, the primary VIF sequence can be deleted to conserve hard disk capacity.  However, white balance and color corrections are done when the VIF files are converted to RGB. For some applications, it may be desirable to retain the primary VIF files so that a modified video clip with different color corrections can be produced from the original raw data.

One-hour capture at 70 MHz, the maximum pixel clock rate, requires approximately 780 GB (8 bits per pixel).  One-hour capture at 25 MHz, the minimum pixel clock rate, requires approximately 260 GB (8 bits per pixel).  Capture for more than 1 hour only requires greater RAID capacity.

What kind of image quality can I expect from the SV9T001C?

Example images are posted at http://www.epixinc.com/gallery/sv9t001.htm.

Low Compression?

The XCAP video to disk feature stores data uncompressed. Thus there are no artifacts as might be introduced by other imaging products that use compression and thereby can get away with smaller disks and/or slower disks. Nor does XCAP use compression when storing in AVI; no artifacts, no loss of information, and no need for custom codecs. When storing as TIFF, XCAP provides an option for lossless compression.

If I mount some super-fast lenses (e.g. f/1.0 ballpark) and shoot at large apertures (maybe using neutral density filters to reduce the light), would the 1/2" sensor give me any shallowness to the Depth of Field (DOF)?

This request is unusual. Most EPIX® customers want to maximize DOF – not minimize it. Because the sensor in the SV9T001C camera measures only 6.55mm x 4.92mm, and because a 35mm SLR (Single Lens Reflex) lens is designed to cover film measuring 36mm x 24mm, a lens designed for use on an SLR camera, when used on the SV9T001C, will produce a much narrower field of view. As a result, you’ll need to use a wide-angle SLR lens to achieve a normal perspective with the SV9T001C. Wider-angle lenses have more Depth of Field than greater focal length (higher magnification) lenses set to the same aperture.

To achieve a particular field of view, a C-mount lens will have a greater focal length than an SLR lens. The C-mount lens will provide a shallower DOF than the SLR lens (when set to the same aperture).

Could I find a way to buy/build a 35mm lens adapter to interface with the C mount?

Adapters are available for less than $80.00. The SLR lens mounts to the front of the adapter just as the lens would attach to an SLR camera body. The rear of the adapter screws into the SV9T001C’s C-mount. Adapters are readily available for Nikon, Canon, Olympus and other popular SLR lens mounts. When an SLR lens is used with the SV9T001C camera, the lens opening (f/stop) and focus are manual adjustments. As a result, there is no advantage to purchasing a lens with automatic adjustments. Older, manual lenses, work just as well.

Can the SV9T001C camera support a heavy lens?

The SV9T001C case is milled from a solid block of aluminum, and is thus rigid enough to support several pounds of lens. However, since the SV9T001C is so light, several pounds of lens – especially a long lens - place an unbalanced torque on the camera and thus the tripod, making the assembly susceptible to vibrations. For long heavy lenses, simply mount the lens to the tripod, and let the lens support the camera. The SV9T001C camera is also available as a printed circuit board without a case (or, if purchased with aluminum case, the case can be opened and the single circuit board can be removed without voiding the warranty). A camera built on a single circuit board simplifies design of a custom enclosure that might be built to permit specialized lens attachment. Note that the IR cut filter, as provided, is attached to the camera case lens mount, and not to the printed circuit board. Equivalent IR cut filters are available, such as B&W 486 or B&W 489, which can be attached to the front of a lens.

Given a fast, modern PC, would I face any bottlenecks or extra expenditures involved with live footage?

Not all “fast, modern PCs” are created equal. The computer must be equipped with at least 2 hard disks in a RAID 0 configuration to allow video-to-disk capture. The computer will need a fast graphics display system if you expect to approach 20 - 30 fps display. The $1495.00 XCAP-Std program is required for video-to-disk capture.

I would expect some difficulties with capture device codecs, which are unlikely your regular video edit codecs.

XCAP software provides image files in industry standard formats. EPIX® Imaging software is not written to limit the ability to port files to other applications. Since XCAP software does not generate compressed image files, there is no need for decompression.

I would expect all kinds of funky workflow-related issues, be they digital (proprietary codecs, proprietary capture devices, driver problems, insufficient RAID…)

The SV9T001C camera and XCAP software provide video output in non-compressed industry standard formats, the capture device is an industry standard PC computer with an available PCI bus expansion slot, our XCAP program is installed by new customers every day – it is designed for easy installation; a two hard disk RAID array is the minimum configuration – EPIX, Inc. will be happy to help determine the drive capacity required for the task.

EPIX, Inc., offers complete imaging systems including camera, software, and the host computer with RAID system installed. EPIX, as an Intel-authorized reseller, typically offers imaging systems based on Intel CPUs and motherboards. Such systems are guaranteed to work to the customer’s written specifications. Ask for a price quotation.

EPIX provides a demo version of the XCAP software that's used to acquire images from the camera, and though I'm just starting to learn its features, it appears that the formats of choice for image acquisition are either TIFF or BMP. I'm assuming that I would be able to capture a sequence of still images that I could then place on a timeline in Adobe Premiere or After Effects, edit and then export in the desired HDTV format.

Yes, a sequence of images can be saved as standard TIFF or BMP files.

Also, for some reason I'm under the impression (though I could be dead wrong - I need a little more research here, too) that the CMOS chip used in this particular camera is the equivalent of a 3-megapixel still camera chip, likely from a digital point-and-shoot or the equivalent; my guess is that it's just controlled through the included PCI board in such a way as to allow for rapid capture of still images, to essentially form the equivalent of progressive-scan video, just captured as a sequence of stills rather than with a traditional video codec. If that's the case, I'm hoping that speaks favorably to the image quality - and at least that would get me in the ballpark of a decent HD video camera, albeit one sourced from the imaging chip of a point & shoot digital still camera.

The SV9T001C camera is based on the MT9T001P12STC CMOS sensor from Micron. It is a 3-megapixel progressive-scan sensor with programmable resolutions and frame rates.

Provided that the camera captures TIFF or BMP sequences, can handle 1080p/24, and has image quality at least comparable to a 3-megapixel digital point & shoot camera - all of which appear to be possible but I still need to verify with EPIX - can you see any other potential pitfalls, better alternatives, or drawbacks to this system that I might not be considering?

The SV9T001C will capture 1920 by 1080 resolution, 27 fps, using a 70 MHz pixel clock. At full 3-megapixel 2048 by 1536 resolution, 18 fps is maximum.

The camera’s strengths include programmable horizontal resolution, vertical resolution, frame rate, pixel clock frequency, and both manual and automatic gain control. Exposure times and frame rates can be set arbitrarily, or can be locked to a multiple of the AC line frequency (50 or 60 Hz) to insure consistent frame illumination. Color balance includes presets for sunlight, fluorescent, and tungsten illumination. Saturation, brightness, and gamma are independently adjustable. Advanced color balance allows calibration using a Macbeth Color Checker.

Potential Pitfalls / drawbacks? When in Video (Free-Run) mode, exposures are through an Electronic Rolling Shutter (ERS).

The examples given are all odd frame rates eg., 20/27/34fps, so unless the software allows arbitrary setting of the pixel clock and/or resolution you won't be getting 'normal' video rates out of it.

The pixel clock frequency is user-selectable over a range of 25 MHz to 70 MHz. with a granularity of 8 KHz to 5 KHz. Both horizontal and vertical resolutions are variable in 2-pixel increments.

It would be awesome if I'm able to squeeze out decent 1080/24p video from a ~$1000 solution!

1080/24p to RAID array requires the $1495.00 XCAP-Std program in addition to the $1095.00 camera.

Would it be possible to obtain a demo unit for testing?
