Auto Gain and Auto Exposure
You can set the camera to automatic exposure control (AEC) to keep the same image
brightness during changing light conditions. You can enable both AEC and automatic gain
control (AGC) independently or together. Auto gain and auto exposure controls let you
control the range of exposure times and gain values used by placing minimum and
maximum limits on these parameters. When both AEC and AGC are enabled together,
exposure times are varied until the maximum exposure time limit is reached, then gain is
applied.
