Restart/Reset

To Set Restart/Reset Mode

The information on one screen can be extracted at any
time by externally inputting Restart/Reset signals (HD/
VD). To enter this mode, set the trigger shutter switches
(6 to 8) on the rear panel of the camera as shown in the
figure below.
The Reset/Restart mode is especially effective for frame
image output with long exposure or a strobe light.
Long exposure
The Restart/Reset function extends the CCD
accumulation time, resulting in highly sensitive
image capture. This function is effective when you
cannot gain satisfactory sensitivity under normal
operating conditions, or when you want to observe
the trail of a moving object. Extend the VD interval
(T) between external VD pulses.
