7. 5 EXT TRIG (External trigger)
Charge begins to accumulate after the trigger input to CC1 of the DIGITAL terminal, and 1 frame images are
output. There are five modes: 1P SNR, 1P SR, PW SNR, PW SR, RR.
( 1 ) 1P SNR (1 Pulse Trigger Sync Non Reset)
Charge begins to accumulate after the trigger input to CC1 of the DIGITAL terminal, and 1 frame images are
output.
(1. 1) 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 "7. 2 (1.3) Changing each setting in E.TRG mode".
*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-
