1. An image processing apparatus comprising one or more processors and/or circuitry which functions as:
an acquisition unit that acquires a plurality of different viewpoint images obtained by shooting a same scene from different viewpoints, and acquires at least one parallax image pair having parallax by pupil division;
a first generator that generates a first distance image from the parallax image pair;
a second generator that generates a second distance image from the plurality of different viewpoint images; and
an integrator that integrates the first distance image and the second distance image and generates an integrated distance image,
wherein the integrator integrates the first distance image and the second distance image by complementing distance information of an area where a subject is moving among distance information constituting the second distance image with distance information of a same area in the first distance image.
