1. An image processing device comprising: a viewpoint separating unit configured to separate multi-viewpoint image data received from a light field camera, into a plurality of single-viewpoint image data for each of the individual viewpoints; a super-resolution processing unit configured to perform super-resolution processing where image resolution is raised to a high resolution for each of the plurality of single-viewpoint image data obtained by separation into individual viewpoints by the viewpoint separating unit, wherein the super-resolution processing unit is configured to detect disparity for each of the plurality of single-viewpoint image data, and perform the super-resolution processing of each of the plurality of single-viewpoint image data using the detected disparity; and a parallax control unit configured to control an amount of parallax between the plurality of single-viewpoint image data of which the image resolution has been raised to the high resolution by the super-resolution processing unit.
