A image processing method according to an aspect of the present invention includes a parallax amount calculating step of calculating a parallax amount of each pixel of a plurality of viewpoint images constituting a multi-viewpoint image; and a parallax amount correcting step of correcting the parallax amount of each pixel, based on a zoom value of the multi-viewpoint image and the calculated parallax amount of each pixel, in such a manner that a different in parallax amount corresponding to an object distance is kept unchanged even if the zoom value is changed, when a parallax amount of each pixel of at least a portion of the multi-viewpoint image is corrected by image processing.
