1. An apparatus for super-resolution enhancement processing, the apparatus comprising: a low-resolution image capturing unit capturing a low-resolution image; a patch pair generating unit dividing each of a plurality of high-resolution images into patches and generating a plurality of patch pairs composed of medium-frequency patches and high-frequency patches for the patches; a patch pair database storing the plurality of patch pairs generated by the patch pair generating unit; and a high-resolution image reconstructing unit dividing the low-resolution image into patches, searching in the patch pair database for a-patch pair including a medium-frequency patch that is similar to that of the low-resolution image, and generating a reconstructed high-resolution image by inserting a high-frequency patch included in the found patch pair into a corresponding patch of the low-resolution image.
