IMAGE PROCESSING APPARATUS, IMAGE CAPTURING APPARATUS, CONTROL METHOD, AND STORAGE MEDIUM

An apparatus generates an image file with a structure including a first area storing a plurality of images and a second area storing metadata. The metadata includes first information for specifying a region in a reference image from among the plurality of images, and second information for specifying another image indicating a different representation of an object of a region specified by the first information. The apparatus sets a region for the reference image, selects, as the another image, an image different from the reference image from among the plurality of images with respect to the region, and generates the image file storing, in the first area, the first information configured for the region and the second information configured for the another image and storing, in the second area, the plurality of images.
