Abstract
An apparatus, medium, and method for correcting color of an image. The apparatus may includes a user interface which displays each of N reference patches, removes non-gray components from the displayed N reference patches, according to the characteristics of a user's visual system, and outputs the reference patches from which the non-gray components have been removed as adjusted reference patches, a table generator which generates at least one lookup table that has, as addresses, color component values for a current image and stores color component values of the adjusted reference patches as data, and a color corrector which addresses the at least one lookup table using the color component values of the image to read data corresponding to correction information for the color component values of the image and outputs the read data as the result of the correcting of color of the image.
