After completion of exposure, internal VD signals are reset and the video will be output 1～2H later.
Internal VD, Composit SYNC, and WEN are output as one-to-one correspondence to the trigger input so that images can
be captured by any of those output signals.
Generally, HD/VD sync singals are unncessary but with external HD signals input, the signals can be synchronized with
internal HD.
Exposure time =
Set value by switch SW1 ～ SW3: 1/60 ～ 1/10000s
Set value by trigger pulse width: 9μs ～ 250ms (Actual time = trigger pulse width + 5μs)
Fixed & Pulse Width Trigger Shutter Mode (Sync Non-Reset Mode)
After completion of exposure, with single external VD input, video can be output from that position. The single external
VD shall be input during the period from 10μs ～ 65ms after completion of exposure time.
External VD input, Composite SYNC output, and WEN output are one-to-one correspondence so that images can be
captured with any signals.
