Abstract
An apparatus for correcting image distortion may correct a luminance level of image data in accordance with a curvature of a curved display panel in a curved display device and a viewing distance of a viewer and display an image optimized for the curvature and the viewing distance on a full area of the curved display panel, whereby an image having no distortion may be provided to the viewer. The apparatus for correcting image distortion includes a virtual curved surface generator, a coordinate mapping unit, and a luminance converter.
