interface modes

Camera Interface Details

Mode 1: Continuous

§ Frame Rate: Matrox Corona-II receives the continuous video from the
camera at 30 frames per second.

§ Exposure time: Exposure time is inversely proportionate to the frame
rate (no shutter) or determined by the shutter setting. Refer to the camera
manual for more information.

§ Camera Switch settings: Internal/External synchronization switch and
DIP switches are set as follows, refer to the camera manual for additional
information:

EXT INT

Mode 2: Asynchronous Reset (Restart/Reset mode)

§ Frame rate: The frame rate is determined by the frequency of the
external trigger signal, up to a maximum of 30 fps.

§ Exposure time: The width (rising edge to falling edge) of the
EXPOSURE1 (EXT. TRIG IN) signal plus a fixed internal camera delay of
1H to 2H equals the exposure time. The exposure time can be modified in
the DCF using Matrox Intellicam or with the MIL digitizer control function
MdigControl(). Refer to the appropriate manual or user guide for more
information.
