(3. 2) Pulse Width Trigger SYNC-NON RESET Picture Output Timing (at Time of Internal Sync)
*1: Externally input signal
*2: Exposure time = Trigger pulse width + 6 µs
(Valid trigger pulse width is 2 µs 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 FVAL/LVAL/DVAL 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.
