□
Trigger input during exposure time shall be ignored in the camera. However, a trigger shorter than 1 frame cycle
should not be used.
□
Triggers can be accepted while outputting video output images. However, please be noted that a trigger signal to
start the next video outputting should not be input before completion of outputting the prior images. (Please refer to
(A) in the drawing below).

FAST Pulse Width Trigger Shutter Mode (ClockSync) CLK Sync. Trigger
(TriggerMode=On, TriggerSyncMode=ClockSync, TriggerActivation=LevelHigh)
□
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., and V-sync. restart system.
The delay time (Exposure Time Delay
①
) from
detecting trigger edge in the camera to actually starting exposure is
approx. 0.13µs. The delay time (Exposure Time Delay
②
) from
detecting trigger edge in the camera to end
exposure is approx. 4.997µs.

Functionally, there is no upper limitation, but noises such as dark noises shadings may be noticeable at long time
exposure.
□
There is an exposure time period for
approx. 4.997μs
at the edge right after exposure output.
