Abstract
In image processing on digital image signals, a color difference due to a type of image sensing device by which the image signals have been acquired is compensated. For this purpose, a characteristic value, such as an average of each digital image signal, is extracted from digital image signals of a plurality of subjects photographed by the same image sensing device. Based on the characteristic value, conversion of each image signal is carried out.
