Abstract
The present invention is directed to improving the accuracy of white balance adjustment. An image input from an image capture deviceis divided into blocks, and white balance gains are calculated from a representative value of each block. Prior to calculation of the representative value of each block, a color range determining circuitdetermines whether each pixel included in each block belongs to a light source color range, or belongs to an apparent object color range. A representative value of that block is calculated from remaining pixels other than pixels determined to belong to the apparent object color range. Thus, by preventing the representative value from being affected by an object color, the accuracy of white balance gains is improved.
