3 Camera Operational Modes
3.1 Normal Mode
3.2 Pulse Width Trigger Mode
In this trigger mode with positive polarity, the camera exposure starts at the rising edge of the trigger pulse and
stops at the falling edge of the trigger pulse. Therefore, if positive polarity exposure is selected, the exposure periods
are the high states of the trigger pulse.
3.2.1 Timing
Note 1: The video output is going to be V reset by the next internal HD signal immediately after the exposure is finished.
The exposure time is set by the pulse width of the trigger signal.
Note 2: The FVAL signal does not output when the exposure by the trigger signal does not exist.
