Input of an external reset-restart signal (CC4 of the DIGITAL terminal: External VD input) permits one screen of
information to be output at an arbitrary timing.

Long Term Exposure
(5. 1)
When sufficient sensitivity is not obtained under normal operating conditions or capturing the trail of a moving object
is desired, the reset-restart function allows high-sensitivity images by extending the exposure time. To achieve this,
please input (from an external source) a VD signal that has an expanded VD pulse and VD pulse interval.
