4.11 Setting Gain

The camera can adjust the analog gain (x1 to x 11.2 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.

Figure 4-11-1 PGA Gain Adjustment



Gain and noise values are proportionally related.



Adjust the amount of gain in accordance with the requirements of your

camera system.
