Pulse Width Trigger Shutter Mode
□
This is the mode to start exposure with external input trigger signals, and set the exposure time with
pulse width of the trigger signals.
□
Trigger operation is H Sync. V-Sync Reset. The delay time (Exposure Time Delay) from
detecting trigger edge in the camera to starting exposure, and from detecting trigger end edge to
completing exposure is max. 1HD.
□
Pulse width is min. 1HD to approx. 2 frames. Functionally, there is no upper limitation, but noises
such as dark noises and shadings may be noticeable at long time exposure.
□
Triggers can be accepted even when outputting video signals. However, trigger signals for
exposure to start the next video output prior to the completion of video transmission for the prior
video output signals cannot be accepted.
□
If the next trigger is input prior to the completion of video transmission for the prior video output
signals, the image may be impacted.
