DESCRIPTION

Input for the signal from CCD area

sensor. 2.5 V bias applied internally.

Feed through level of the input

signal is clamped to this pin voltage.

2.9 V bias applied internally.

Connect capacitor between this pin

and GND.

Gamma adjustment of the exposure

circuit. This pin is preset to 3.1 V,

and gamma becomes 0.45 at open.

Window pulse input for the exposure

circuit. Outputs the signal while "H".

Output for the exposure signal.

Connect a resistor between this pin

and GND.
