METHOD AND APPARATUS FOR CONTRAST ENHANCEMENT

摘要

A method of enhancing a contrast and an apparatus for enhancing a contrast are provided. The method of enhancing the contrast includes: dividing an image into a plurality of blocks and calculating an average luminance value of each block; interpolating a peripheral luminance value for each input pixel of the image by using the average luminance value; and enhancing the contrast of the input pixel by using the interpolated peripheral luminance value of the input pixel and a unique luminance value of the input pixel.
