Automatic Gain Control (Agc) - Microscan MS-Q Imager User Manual

Automatic Gain Control (AGC)

AGC is a system that controls gain in order to maintain high performance over a range of
input levels. Gain is essentially the ratio of output to input. Gain settings affect how the
MS-Q decodes symbols and captures images.
AGC Selection
The MS-Q has two different types of gain control. Decoder AGC, the default setting, is
optimized for decoding 1D and 2D symbols. Imager AGC is optimized for capturing images.
AGC Frame Adjust Count
AGC Frame Adjust Count sets the number of image frames captured and discarded
before the main image capture. This feature gives the gain control time to adjust.
Minimum Exposure
Minimum Exposure is a percentage value that represents the minimum exposure
allowed for image captures.
Maximum Exposure
Maximum Exposure is a percentage value that represents the maximum exposure
allowed for image captures.
