4.10 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 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.
