Abstract
An original image signal made up of a plurality of image signal components each representing a pixel of an original image is processed to suppress the granularity of the original image and enhance the sharpness of the original image, and a final processed image signal is obtained. Processing for suppressing granularity and processing for enhancing sharpness are carried out separately on the original image signal to obtain a granularity-suppressed image signal and a sharpness-enhanced image signal. At least one intermediate processed image signal is obtained by operation based on at least the granularity-suppressed image signal and the sharpness-enhanced image signal, and, as the image signal component for each pixel of the final processed image signal, the image signal component for the corresponding pixel of an image signal selected from the intermediate processed image signals and the original image signal is taken according to an indicator value calculated on the basis of the granularity-suppressed image signal, the sharpness-enhanced image signal and the original image signal.
