Abstract: An apparatus for detecting an afterimage candidate region includes: a comparison unit which compares gradation data of an n-th frame with integrated gradation data of an (n−1)-th frame and generates integrated gradation data of the n-th frame, where n is a natural number; a memory which provides the integrated gradation data of the (n−1)-th frame to the comparison unit and stores the integrated gradation data of the n-th frame; and an afterimage candidate region detection unit which detects an afterimage candidate region based on the integrated gradation data of the n-th frame, where each of the integrated gradation data of the n-th frame and the integrated gradation data of the (n−1)-th frame comprises a comparison region and a gradation region.

Abstract: A display device includes: a similar gray level block detector configured to detect a pixel data block in which a gray level difference between a plurality of pixel data included in an image signal is smaller than or equal to a threshold; a skin tone detector configured to detect the pixel data block including a skin tone; and a gamma processor configured to apply a first gamma to a plurality of pixel data included in the pixel data block when the pixel data block does not include the skin tone and apply a second gamma to the plurality of pixel data included in the pixel data block when the pixel data block includes the skin tone.
