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

Figure 4-7-1 PGA Gain Adjustment

◆

Gain and noise values are proportionally related.

◆

Adjust amount of gain in accordance with the requirements of your camera system.
