Provided is an apparatus and method for super-resolution enhancement
processing. The apparatus includes a low-resolution image capturing unit,
a patch pair generating unit, a patch pair database, and a
high-resolution image reconstructing unit. The low-resolution image
capturing unit captures a low-resolution image. The patch pair generating
unit divides each of a plurality of high-resolution images into patches
and generates a plurality of patch pairs composed of medium-frequency
patches and high-frequency patches for the patches. The patch pair
database stores the plurality of patch pairs generated by the patch pair
generating unit. The high-resolution image reconstructing unit divides
the low-resolution image into patches, searches 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 generates 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.
