( 3 ) PW SNR (Pulse width trigger SYNC-NON RESET)

The trigger input to CC1 of the DIGITAL terminal develops 1 frame images.

The internal VD falling edge is within the

exposure period and thus video is not output. *3

*1:

Externally input signal

 

 

 

 

 

*2:

Exposure time = Trigger pulse width + 6 s

 

 

 

(Valid trigger pulse width is 2 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 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.
