Abstract:
Provided is an image correction method and apparatus which can enhance the performance of image correction without deteriorating image quality. The image correction method includes creating a cumulative density function (CDF) based on a luminance histogram of an input image; calculating a plurality of correction parameters, which will be respectively applied to a plurality of different luminance adjustment functions, based on the CDF of the input image; and correcting luminance of the input image using the correction parameters and the luminance adjustment functions.
