Camera Settings
Camera Settings
Camera Settings allow you to set AGC Sampling Mode, to set the percentage values for
Illumination, Exposure, and Gain, to set the AGC Frame Adjust Count, and also to define
Window of Interest dimensions.
AGC Sampling Mode
When AGC Sampling Mode is set to Automatic (default), each time a No Read occurs,
the reader adjusts the gain and exposure for the next capture to optimize symbol contrast.
The values for Illumination, Exposure, and Gain can be set to any value between 0%
and 100%. The default values are shown below.
AGC Frame Adjust Count
Automatic Gain Control (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 reader decodes symbols and captures images.
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.
