A test pin. Set open or to L level in the normal mode.
An input pin to control electronic exposure using EEUD
(pin 35) and EENR (pin 36).
An output pin for window pulse.
WIND1 : When connected to EEST (pin 2), the
WIND2 : A pulse that picks out the center of CCD output.
An input pin for resetting internal vertical counter.
The input pulse is VSYNC (negative polarity).
A test pin. Set open or to L level in the normal mode.
A test pin. Set open or to L level in the normal mode.
A grounding pin.
Supply of +5 V power.
An output pin of composite synchronous signal pulse.
An output pin of composite blanking pulse.
A pulse to clamp the optical black signal. This pulse
stays low during the absence of effective pixels within
the vertical blanking.
A pulse that corresponds to the cease period of the
horizontal transfer pulse.
