ABSTRACT:
A normal AWB (auto white balance) correction value is calculated based on inputted image data. Further, a face area is identified from the inputted image data and a face AWB correction value is calculated based on image data in the face area. Then, first feature data and second feature data are extracted from the inputted image data and image data in the face area, respectively. A total AWB correction value is calculated in accordance with at least one of the face AWB correction value and the normal AWB correction value based on a comparison result of the first feature data and the second feature data. Thus, an erroneous correction can be prevented in an AWB correction using a face detection function.
