Abstract
An automatic color balance control method is used for color balancing an image including a foreground object and a background. The background is extracted from the image by an object detection procedure. Then, the background is analyzed to get the color deviation information. According to the color deviation information, the control method adjusts the gain value to adjust the color value of the image. Accordingly, the present automatic color balance control method can properly adjust the color of the image according to the light source without being affected by the moving foreground objects.
