( 3 ) PW SNR (Pulse width trigger SYNC-NON RESET)
The trgger input to the RGB terminal develops 1 frame images.
(3. 1) 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 + 6
µ
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 trig-
ger, there will be an effect on the video.

258H (Partial scanning 90fps) The internal VD falling edge is within the exposure
period and thus video is not output. *
