Exposure time shall be the value set by the trigger pulse width.
In case of SYNC Reset mode
Internal VD is reset after completion of exposure and video output signals are read out after 1 ～ 2H.
Internal VD, Composite Sync, and WEN signals are one-to-one correspondence to trigger input so that
capturing images can be done with any output signals.
HD/VD sync signals are not necessary basically, but signals can be synchronized with internal HD with
inputing HD signals externally.
Exposure time = Trigger Pulse Width (μs) + 96μs at 30fps.
Trigger Pulse Width (μs) + 48μs at 60fps.
In case of SYNC Non-Reset mode
Video output signals are read out at the first VD position generated after completion of exposure.
Single VD should be input between 10μs ～ 65ms after completion of exposure.
External VD input, Composite Sync, and WEN signals are one-to-one correspondence so that any
signals can be used to capture images.
Exposure time = Trigger Pulse Width (μs) + 96μs at 30fps.
Trigger Pulse Width (μs) + 48μs at 60fps.
