1. An image processing device comprising: a calculation unit that searches for an approximate pixel from among a plurality of candidate pixels which approximates an occlusion pixel based on a detected temporal minimum vector between the approximate pixel and the occlusion pixel between right-eye and left-eye parallax maps and calculates a correction parallax vector of the occlusion pixel based on a comparison between a parallax vector of the occlusion pixel and a parallax vector of the approximate pixel, wherein the temporal minimum vector is a value which is a minimum within a predetermined time among a plurality of parallax vectors corresponding to each of the plurality of candidate pixels in a predetermined region including the occlusion pixel; and a correction unit that corrects the parallax vector of the approximate pixel according to the calculated correction parallax vector of the occlusion pixel, wherein the calculation unit and the correction unit are each implemented via at least one processor.
