5-4-5. GAIN
(1) By L or R button, the gain control modes can be selected.
① LOW
This fixed-gain mode keeps the sensitivity low for brighter spots.
This can be used for relatively comfortable picture reproduction with less
video noise. Normally it is used with ample light condition.
② MID
This fixed-gain mode keeps the sensitivity middle between HIGH and LOW.
③ HIGH
The fixed-gain mode keeps the sensitivity high for darker scene.
④ AGC
This mode is initially set to automatically optimize the sensitivity and noise
levels.
⑤ HYP-AGC
This mode is higher in sensitivity than normal AGC mode for very dark scene.
Then, sometimes pictures may look rugged and maybe with conspicuous
video noises, due to forced higher sensitivity to reproduce dark scene.
* In Day/Night mode with Automatic operation, only AGC and Hyper AGC are
available for Gain selection.
