Abstract
A method for processing an image includes acquiring a low frequency component of a luminance component of an image, correcting the luminance component of the image using the acquired low frequency component, determining a level correction amount of each pixel of the corrected image using a frequency distribution of low frequency components of the acquired image and a low frequency component of each pixel of the image, and performing level correction using the determined level correction amount and a luminance distribution of the corrected image.
