IRIG - sync Operation
This camera system supports IRIG - sync operation, in which the sensor drive signal is
synchronized with the input of IRIG - B signal.
◼
How IRIG-sync operation works?
In IRIG - sync operation, the image sensor is driven by the timing signal shown below.
Exposure to the sensor starts at the start of the IRIG - 1PPS signal
IRIG-B
：
IRIG code that is input to the camera
IRIG-1PPS
：
1PPS timing of the IRIG code
EXPOSURE
：
Exposure to the camera sensor (exposure is indicated by high duration)
CAM_V
：
Camera’s vertical sync signal
