Abstract
A processed image signal is obtained from an original image signal representing an original image by carrying out on the original image signal an image processing based on a signal representing information on a high frequency component of the original image signal. Band-limited image signals are made from the original image signal, and a signal representing information on a high frequency component of the original image signal is obtained from the band-limited image signals on the basis of a predetermined transformation function. The image processing is carried out on the original image signal on the basis of the signal representing information on a high frequency component of the original image signal.
