3.4.2. Shutter Setup and Exposure Period
When shutter is not used, the whole period defined by 1/Framing Rate (sec) is virtually the
exposure period for each framing cycle. There is no reset period during this framing cycle.
When shutter is used, the exposure period is defined by the current shutter speed and is preceded
by a reset period.
