Gain Control
1) Gain control
Selects gain control method from “Fixed gain” and “Auto (AGC)”.
2) Gain value
Sets the gain for fixed gain control.
3) AGC minimum gain, AGC middle gain and AGC maximum gain
The gain for AGC is changing automatically with these settings, based on brightness of object.
It is necessary to set minimum, middle and maximum AGC gain as below order.
AGC minimum gain <= AGC middle gain <= AGC maximum gain
4) AGC tolerance
The AGC process will be stop when differences between “ALC target brightness” and current brightness
becomes smaller than AGC tolerance.
5) AGC threshold
The AGC process will be start when differences between “ALC target brightness” and current brightness
becomes greater than “(AGC tolerance + AGC threshold)”
6) AGC speed
The maximum amount of gain change for AGC control is limit by this setting.
