Abstract
Provided are an image processing method and apparatus for enhancing contrast. The image processing apparatus includes a determination unit that determines whether contrast enhancement processing should be performed on an input image; an intensity mapping unit that generates a plurality of images having different exposure times from the input image, using intensity mapping, if the contrast enhancement processing should be performed on the input image; and an image composition unit that composes the plurality of images into a composed image. Therefore, it is possible to reduce a color change or a false contour phenomenon that are generated in a related art contrast enhancement process.
