( 5 ) RR (Reset restart)
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.

(5. 1) Long Term Exposure
When a sufficient sensitivity is not obtained with the normal operation conditions or capturing the trial of a
moving subject 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.
