( 5 ) RR (Reset restart)

Input of an external reset-restart signal (VD terminal) permits one screen of information to be output at an arbitrary timing.

(5. 1) Long Term Exposure

When the camera is used and sufficient sensitivity cannot be obtained for the reset-restart function under normal operating conditions, or when observation of the trail of a moving subject is desired, the exposure time can be extended to allow high-sensitivity images to be obtained. To achieve this, please input from an external source a VD signal that has an expanded VD pulse and VD pulse interval.
