Abstract
An aspect of the present invention features an apparatus for compensating color deviation of an image that has uneven color deviation. The apparatus can comprises: a color deviation analyzing module that analyzes luminance of each color component of each pixel composing the image and determines a color component having the highest or lowest rate of luminance change as an object color component, wherein the rate of luminance change is analyzed in the direction from a central pixel to a corner pixel of the image; a compensation table generating module that creates a plurality of sections from a beginning point, depending on a distance from the central pixel, and generates a compensation table for boundary pixels of each section with compensation values that are produced based on the luminance of the object color component; a compensation image generating module that generates a compensation image for the whole image, using the compensation table; and a compensating module that compensates the color deviation by applying the compensation image to the image.
