Brightness tolerance for AGC control
The AGC control is stopped when differences between “target
brightness” and current brightness of image is smaller than this
value.

The formula of gain:
G [dB] = 0.3 x gain setting
The interlock between auto exposing control (ALC) and auto gain control (AGC)

Dark AGC maximum gain
It is necessary to set minimum, middle and maximum AEE exposure time and AGC gain as below order.
AEE minimum exposure time <= AEE middle exposure time <= AEE maximum exposure time
AGC minimum gain <= AGC middle gain <= AGC maximum gain
