Method and apparatus for enhancing contrast
A method of enhancing contrast includes obtaining a first luminance histogram of an input image; generating a second luminance histogram through pixel redistribution for the first luminance histogram; computing a conversion function based on both a first cumulative density function based on the first luminance histogram and a second cumulative density function based on the second luminance histogram; and changing the luminance distribution of the input image based on the conversion function.
