Choose one of Auto Gain modes: “Once” or “Continuous”. Under “Once” mode, the algorithm will adjust
the Analog Gain only once, and then the feature will be set to OFF. Respectively under “Continuous” mode,
the gain will be adjusted continuously.

7.3.4
Combined Auto Exposure & Auto Gain Mode
When operating in this mode, the camera tries to reach the preferred picture brightness by adjusting both
Exposure and Analog Gain values. If the camera’s image intensiveness is under desired brightness level, the
algorithm first increases exposure value to make the picture brighter. If exposure level is at maximum value, while
preferred brightness level is not reached yet, the algorithm starts to modify Gain Level and adjust exposure level
accordingly.
This mode is operational only when both Auto Exposure and Auto Gain are set to “Continues” mode.
Steps to set Combined Auto Exposure and Auto Gain Mode:
1.
Define the parameters for Auto Exposure; please see the section 7.3.3.1 for detailed instructions.
2.
Set Auto Exposure to “Continuous” mode.
3.
Define the parameters for Auto Gain; please see related section 7.3.3.2 for detailed instructions.
4.
Set Auto Exposure to “Continuous” mode.
7.3.5
Brightness Level
The Desired Brightness Level reflect the average value of all pixels in the defined ROI. The value range of the
Desired Brightness Level depends on the output pixel bitness. e.g. for a 10bit output the value should be between
0 and 1023, while for 12bit output the value should be between 0 and 4095.
