Abstract:
An image processing method of processing an original image signal made up of a plurality of image signal components each representing a pixel of an original image and obtaining a final processed image signal, the method comprising the steps ofcarrying out processing for suppressing granularity and processing for enhancing sharpness separately on the original image signal to obtain a granularity-suppressed image signal and a sharpness-enhanced image signal, obtaining at least one intermediate processed image signal by operation based on at least the granularity-suppressed image signal and the sharpness-enhanced image signal, and taking, 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 original image signal and the intermediate processed image signal(s) 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.
