ImageNation makes video frame grabbers in a variety of
configurations and options.

CX100 Precision Video Frame Grabber
The CX100 Video Frame Grabber is a precision image capture board in
the ISA bus configuration. It is an 8 bit, half slot card ideal for
compact applications. Compatible with monochrome video in either
NTSC or CCIR formats. Allows real time capture to dual port video
RAM mapped into the computer's memory. This provides fast, random
access to the captured image for even the most demanding image
processing needs. The image transfer rate is 1 Mbyte per second. The
CX100 also has a display output for viewing live video or a captured
image on an external monochrome monitor. Analog RGB, 30 Hz
interlaced video output is an option available for false color
display (this is not VGA compatible). In addition, there is a
trigger input for synchronizing image acquisition to an external
event or for operation with an asynchronous (resettable) camera.
The CX100 is a +5 volt only design. It consumes less than three
watts and has a power down mode. The all digital synchronization
scheme provides a rock solid image and an +/- 3 nS sampling jitter
specification. Video noise is less than one LSB (least significant
bit). The automatic detection of NTSC or CCIR video, coupled with
the excellent jitter performance, ensures operation with standard
and resettable cameras as well as video recorders. Hardware
controlled field or frame grab, software adjustable offset and gain,
automatic look up table (LUT) load and non-volatile configuration is
supported. Input and output LUTs allow gamma correction, contrast
and brightness adjustment, and thresholding in real time. The
optional overlay RAM allows text and graphics to be displayed on top
of live video or a captured image. The video overlay can display 15
LUT selectable colors (gray levels).
Lots of software support is also provided. Software and examples are
available on ImageNation's BBS.
ImageNation ImageNation also offers versions of the CX frame grabber
in the compact PC/104 format. PC/104 is the familiar ISA bus in a
compact, low power, 3.6 X 3.8 inch format. It is ideal for embedded
applications. ImageNation supports multiple camera and display
applications with a four to one video multiplexor available in ISA
or PC/104 versions. Contact ImageNation today for more information.

"Imaging Technology Inc."
55 Middlesex Turnpike
Bedford, MA 01730-1421
tel: 617.275.2700
fax: 217.275.9590
Offers a modular vision system that can be taylored for the
application. Both VME and PC ISA/VL-bus platforms are supported. It
seems likely, however, that when all the required modules are
selected, the system will have a fairly large pricetag.
A system consists of an 'image manager' or IML which is either a VME
or PC ISA/VL-bus compatible board. It contains some framstore memory
and a slot for the 'acquisition module'. For the PC version, the IML
can be used as the system VGA adapter, eliminating the need for a
separate display card or module. To add one of the many available
computational modules, the 'Computational Module Controller' or CML
must be purchased, which also plugs onto (sort of) the IML. The CML
has slots for either one or two plug-on computational modules. So,
as you can see, it adds up quick. About $23k for a system with 2 C31
DSP computational modules. Device drivers are available for
DOS/Windows, VxWorks, OS-9, and Solaris.
There are 4 available acquisition modules:
1. Variable Scan: interfaces to RS-170 and CCIR cameras
2. Fast Analog Acquisition: interfaces to high frame rate analog
cameras
3. Color Acquisition: interfaces to NTSC, PAL, RGB or multiple
RS-170/CCIR cameras. One interesting feature of this module is the
ability to program your own color space. Otherwise, it supports
HSI, YUV, YIQ and YCrCb color spaces.
4. Digital Acquistion: interfaces to RS-422 or TTL video sources.

There are 5 available computational modules:
1. Convolver/Arithmetic Logic Unit (CM-CLU): Accelerates convolution.
e.g. a 4x4 convolution on an 8-bit 512x512 image takes 7.5 ms.
2. Programmable Accelerator (CM-PA): Contains a TMS320C31 DSP from TI
(which can be programmed in C), 4Mb image memory and 1Mb of
EEPROM.
3. Histogram/Feature Extraction Processor (CM-HF): Performs realtime
histograms and feature detection.
4. Median and Morphological Processor (CM-MMP): performs
morphological filtering, erosion, and dilation.
5. Binary Correlator (CM-BC): Performs high-speed template matching
and binary morphology.
