4.10 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.
Analog gain can be changed by sending the
”gax” command.
Digital gain can be changed by sending the
“gdx” command.
