AEC/AGC

AEC/AGC enables both Automatic Exposure Control and Automatic Gain Control. In this mode, the optimal settings for exposure (shutter) and gain are computed and updated for every frame. It may take several frames to adjust the shutter and gain values to the correct settings.

Important: In this mode, only the Automatic Exposure Control (AEC) is active while the gain value remains fixed at its minimum setting. The Automatic Gain Control (AGC) only becomes active if the AEC has driven the shutter value to its minimum (slowest) setting and the desired image brightness has still not been obtained. When this occurs, the shutter value will remain fixed while gain is adjusted. The current camera shutter and camera gain parameters are then updated at the end of the read cycle (see Camera Settings).
