Pulse Width Trigger SYNC-NON RESET Picture Output Timing
(At Time of One-shot or Continuous External VD/Continuous External HD Input)
*1: Externally input signal
*2: Exposure time = Trigger pulse width + 97

s
(Valid trigger pulse width is 2
µ
s or greater for external trigger shutter operation.)
*3: Video is output at the falling edge of the internal VD following completion of the exposure
period.
The video and the VIDEO INDEX have a paired relationship.
NOTE
When the next trigger is input before completion of the output of the video corresponding to
the trigger, there will be an effect on the video.

*1: Externally input signal
*2: Exposure time is determined by the setting of the MODE SELECT switch. Refer to page 9.
As long as there is no external sync input, the internal VD will be output when the rear
panel HD/VD signal input/output switch is set to the INT side.
*3: Video is output at the falling edge of the internal VD following completion of the exposure
period.
The video and the VIDEO INDEX have a paired relationship.
NOTE
When the next trigger is input before completion of the output of the video corresponding to
the trigger, there will be an effect on the video.
