Claim:
An apparatus for correcting color of an image, the apparatus comprising: a user interface to display each of N reference patches, with N being a number greater than or equal to 1, to remove a non-gray component from a displayed selected reference patch, of the N reference patches, selectively overlaid on a displayed corresponding background, based on user interaction and according to characteristics of a user's visual system, as an adjusted reference patch, and to output the adjusted reference patch, wherein the user interface includes a user patch manipulator to be manipulated by the user to control display characteristics of the selected reference patch, overlaying the displayed corresponding background, with the user patch manipulator being displayed as an overlay within the displayed selected reference patch; a table generator to generate at least one table comprising color component values, as addresses, and storing color component values of the adjusted reference patch as data in the at least one table; and a color corrector to address the at least one table, using color component values of the image, to read data corresponding to the color component values of the image and output the read data for a color corrected image, wherein the user interface displays a plurality of paired reference patches and backgrounds, pair by pair, removes non-gray components from the displayed reference patches, according to the characteristics of the user's visual system, matches luminances of the displayed reference patches with luminances of displayed backgrounds, according to the characteristics of the user's visual system, as adjusted references patches, respectively, and outputs the adjusted reference patches, wherein each of the plurality of pairs includes one predetermined reference patch paired with one predetermined background.
