Abstract
An afterimage compensator includes: a global shifter configured to determine an upscaling area and a downscaling area of a display unit, that together correspond to a preset global shift path, to shift a main image of the display unit; a logo shifter configured to analyze image data corresponding to a logo image and a preset logo peripheral area surrounding the logo image, and configured to determine a logo upscaling area and a logo downscaling area that are each included in the logo peripheral area, the logo shifter being further configured to shift the logo image; and a scaler configured to combine the upscaling area, the downscaling area, the logo upscaling area, and the logo downscaling area and configured to scale image data corresponding to the combined scaling area.
