Abstract
Color reproduction ranges for images of subjects taken in the light of plural light sources each having plural color temperatures are previously stored. First, a predetermined chromatic characteristic of an input image is analyzed, thereby determining whether the image needs white balance correction or not. If the image is determined to need white balance correction, a color reproduction range close to the color distribution of the image is selected from among the color reproduction ranges previously stored, and white balance correction adapted for a color temperature associated with the color reproduction range is performed.
