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 CLK Sync. HV-Sync Reset. The delay time (Exposure Time Delay) from detecting
trigger edge in the camera to starting exposure is approx. 330ns. And, the delay time from detecting
trigger end edge to completing exposure is approx. 270ns.
□
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 edge part of trigger signals is overlapped with video outputting period, 1 line noise may be
detected on the video output screen. To input trigger signals during video output period, set the data
003 to the address 014 (Trigger input signal, camera internal H sync ON). External trigger signals are
synchronized with camera internal H signals so that max. 1HD jitter to Exposure Time delay would
occur.
□
When changing the camera to pulse width trigger shutter mode, the first output image can be unstable.
Please input the first trigger as a dummy to ignore and take the second and after as the actual triggers.
※
Video output signal delays by 2H from Exposure Time.
