1 Pulse 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 is determined by the setting of the MODE SELECT switch. Refer to page 9.
*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.

*3: VD is generated after 0 to 1H following the completion of the exposure period and the
video is synchronized to this and output.
