acquiring a plurality of viewpoint images;
generating, by a processing unit, distribution information related to an image shift based on (a) differences of contrast between the plurality of viewpoint images and (b) an image shift amount between at least two of the plurality of viewpoint images, wherein the distribution information is generated so that (a) the image shift amount is used in response to the differences of contrast being lower than a threshold and (b) the image shift amount is not used in response to the differences of contrast not being lower than the threshold; and
outputting or recording the distribution information by the processing unit, wherein the distribution information is output or recorded for performing image processing, and
