Cautions in the Long Time Exposure Mode.
1. Theoretical exposure time is as follows. EIA: 1/30 sec. to
∞. CCIR: 1/25 sec. to ∞.
2. It is recommended not to use exposure >2 sec. since visible dark-current noise may occur.
3. Ext. HD signal (4.0 Vp-p ± 2.0V at 75 Ohm terminated) has to be input continuously
The falling edge of Int. HD signal and Ext. VD signal are phase-synchronized.
4. Timing of ext. VD signal in each accumulation mode has to be set, as described before.
a) 2:1 Interlaced mode (Field accumulation mode)
b) 2:1 Interlaced mode (Frame accumulation mode)
c) Non interlaced mode (Field accumulation mode)
