Abstract
Provided is an apparatus for correcting color distortion, including a color model generation unit configured to generate an original color model and a distortion color model, wherein the original color model includes colors which correspond to each coordinates of RGB color space and a lossy compression and color improvement operation are performed to the original color model to generate the distortion color model, a color space conversion unit configured to generate a converted original model and a converted distortion model by converting each value of the RGB color space included in the original color model and the distortion color model into color values of L*a*b* color space, a correction matrix computation unit configured to compute a correction matrix which converts each color value of the converted distortion model into each color value of the converted original model; and a color correction unit configured to correct color of a distortion image which is externally inputted by using the correction matrix.
