4.11 Setting Gain
The camera can adjust the analog gain (x1 to x11.2 in 21 steps) and the digital
gain. As shown in the figure below, increasing the gain setting increases the
gradient 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.
