Abstract
A method and an apparatus enhance a local luminance of an image, and a computer-readable recording medium stores a computer program that enhances a local luminance of an image. The method includes: selecting a local area with a luminance to be compensated for from a luminance space, the luminance space representing a luminance of the input image; and compensating for the luminance of the selected local area.
