Gain
Setting gain above 0 dB (default) is another way to boost the signal
coming from the sensor. Especially useful for low light conditions.
Setting Gain amplifies the signal of individual or binned pixels before the
ADC.
Referring to Photography adding gain corresponds to increasing ISO.

NOTICE
Gain also amplifies the sensor’s noise. Therefore, gain
should be last choice for increasing image brightness.
Modifying gain will not change the camera’s dynamic
range.

Auto Gain
For automatic adjustment of Gain please refer to
Please note, with CMV4000 sensors gain adjustment is possible in steps
only. Please find step values are as below.
When using autogain with steps of gain the non-continous gain
adjustment might be visible in final image. Depending on your
application it might be preferrable to use fixed gain values instead and
modify exposure with exposure time.
