5.3 Automatic Gain Control
Automatic gain control (AGC) enables the camera to maintain the same image brightness
during changing light conditions. In AGC mode, you can set the image luminance (brightness),
and the camera will adjust the gain accordingly. Luminance options are average or peak.
The camera starts by changing the gain within the specified min-max limits.
•
If reaching one of the gain limits, the camera indicates the limit has been reached
and maintains this value until the light condition change. You can set the speed of
convergence from four possible options.
•
If enabling AEC mode and AGC mode together, the camera starts by changing the
exposure first within the specified min-max limits until the maximum exposure limit
is reached.
•
Upon reaching the maximum exposure limit, the camera adds gain and changes it
within the specified min-max limits.
The AEC/AGC algorithm samples all pixels for the entire frame. The camera displays the
current luminance within the frame, the current exposure, and the current gain.
The POE-C2000 and POE-C2400 cameras do not support Automatic Gain Control.
5.4 Acquisition Control
You can control acquisition by selecting mode (see
), number of frames to capture,
acquisition frame time and frame rate. You can extend the actual frame time beyond the free-
running frame time up to 16 s.
