 The FastCamera40
is a high-speed megapixel digital camera system,
based on a CMOS imager with a global electronic shutter. This
camera has a high-speed,
scaleable, integrated FPGA and memory subsystem which enable
stand-alone
high speed in-camera image processing. When integrated with a camera
link framegrabber/coprocessor board, the resulting
system capabilities can
be expanded by adding processors and memory on the board
according to
the needs of the user. Another
option is the USB2.0
version which allows the full rate capture of events in the camera for
eventual downloading.

CAMERA
CONTROL INTERFACE:
- USB2.0 control with USB2.0 option
- FastCamera40 uses
RS-644
serial communication as specified in the Camera LinkTM
standard
- The RS-644 serial
connection
in the Camera LinkTM interface is used
to issue
commands to the camera for changing modes and parameters
- The serial link
can also
be used to query the camera about its current setup
MODES
OF OPERATION:
The system
supports
a wide range of custom user selected ROIs and operating modes.
For example,
full resolution 2352x1728 frames at 240 fps with smaller ROI
speeds of
up to 100x100 pixels at 4000 fps , 1X 2352 pixels at 400,000
fps.There is a wide range of availble real-time algorithms such as:
-
Image storage up to 800 full size frames at
full speed without compression
-
Image averaging
-
By pixel gain and offset calibration
-
Programmable ROI (via serial port)
-
Image sub-sampling
-
Convolution filtering
-
Binarization with dynamic threshold
-
Lossless and lossy real-time compression at
full speed using VHDL and Verilog compatible IP
-
VHDL customizable
processing
The system can be provided with dedicated software to perform gauging,
tooling and pattern matching in the camera. Thus providing a stand-alone
system for real-time, flexible measurement and pattern analysis
applications.
