3.4 Edge Preset Trigger Mode (Trigger Input While the Image Is Out)
In this trigger mode, the camera exposure starts at the rising edge of the trigger pulse.
If trigger signal input is required while the image is out, then it is necessary to disable the trigger signal
mask with the communication.
To avoid generating additional noise on the image, it is necessary to set the “H reset” at the exposure start
mode.
3.4.1 Timing
Note 1: The video output will be V reset by the next internal HD signal immediately after the exposure is finished.
Note 2: The exposure time is set by the preset electronic shutter speed.
