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, and from detecting trigger end edge to
completing exposure is 370ns.
□
Pulse width is min. 10
μ
s 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 can not be accepted.
If the edge part of trigger signals is overlapped with video outputting period, 1 line noise may
detected on the video output screen. To input trigger signals during video output period, set the
data of address 018 to 001 (Trigger input signal, camera internal H sync ON). External trigger
signals are synchronized with camera internal H signals so that approx. 3.583
μ
s jitter to Exposure
Time delay would occur.
