4.7 Setting Gain
The camera can adjust the analog gain (x1 to X10.0 in 8 steps) and the digital gain.
As the diagram below indicates, increasing the gain setting increases the slope of
the camera’s response curve and results in a higher camera output for a given
amount of light.
See section 4.2.5.1 for setting Analog gain and section 4.2.5.2 for setting Digital
gain
.
