Auto White Balance, Exposure and Gain Algorithm Control
Auto Algorithm Control lets you configure settings for AWB (Automatic White Balance),
AEC (Automatic Exposure Control), and AGC (Automatic Gain Control) algorithms.
You can set the camera to AEC/AGC to keep the same image brightness during changing lighting
conditions. On the Auto Algorithm Control panel, you can configure the range of exposure times
and gain values for AEC/AGC by placing minimum and maximum limits on these parameters.
