Figure 85: uEye properties - AWB
Every light source has a specific color temperature. Images captured with a camera can
have a reddish (low color temperature) or bluish hue (high color temperature), depending
on the color temperature of the light. This hue can be corrected by white balancing.
To carry out white balancing, aim the camera at a surface of a uniform gray color. You can
perform white balancing either manually with the RGB gain control or by using the uEye's
Auto White Balance (AWB) function.
