ABSTRACT:
In order to perform a brightness correction that is suited to a face image in a moving image, a still-image brightness correction parameter for performing a brightness correction suited to a subject image is calculated from a face image in the subject image and the overall subject image. A moving-image brightness correction parameter is calculated using the calculated still-image brightness correction parameter and a moving-image brightness correction parameter that has been calculated in a subject image of a previous frame. By using the moving-image brightness correction parameter calculated, the brightness of a subject image obtained subsequent to the first-mentioned subject image is corrected.
