A method and apparatus for compensating for image distortion, which compensate for a difference between an input image signal and an output image signal of a display apparatus, are provided. An apparatus for compensating for distortion of an image which is output from a display unit for an image display apparatus includes an image reading unit which reads an output image which is output from the display unit, an image comparison unit which estimates a difference between image characteristics of the read output image and image characteristics of an input image and creates compensation information which compensates for the difference, and a compensation unit which compensates for distortion of the output image by correcting an original image using the compensation information. |
