ABSTRACT:
When the image of a face is detected from within the image of a subject, the brightness of the face image is calculated. If it is determined that the face image is dark are requires a correction, a revised gamma correction curve is calculated in such a manner that both the face image and the overall image of the subject take on the appropriate brightness. A gamma correction is applied using the revised gamma correction curve. Noise reduction processing is executed in order to suppress the amount of noise produced by the gamma correction.
