    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: An image processing method includes: receiving an input image signal (IIS); doubling the IIS into frames; determining a TGM mode to control an order in which gamma curves (GC) are to be applied to the doubled IIS, the GCs including first and second GCs; applying the GCs to the doubled IIS based on the TGM mode to generate a doubled, TGM-processed image signal (DTIS); correcting the DTIS to generate a corrected image signal (CIS); and dither-processing the CIS to generate an output image signal. The dither-processing of the CIS includes: performing dither-processing by sequentially applying dithering patterns (DP) of a first DP set to the CIS in association with first ones of the frames with respect to the first GC, and performing the dither-processing by sequentially applying DPs of a second DP set to the CIS in association with second ones of the frames with respect to the second GC.

    Abstract translation: 一种图像处理方法包括：接收输入图像信号（IIS）; 将IIS翻倍成框架; 确定TGM模式以控制将伽马曲线（GC）应用于双倍的IIS的顺序，GC包括第一和第二GC; 基于TGM模式将GC应用于双倍的IIS，以生成加倍的TGM处理的图像信号（DTIS）; 校正DTIS以产生校正图像信号（CIS）; 并对CIS进行抖动处理以产生输出图像信号。 CIS的抖动处理包括：通过相对于第一GC与第一帧相关联地将CIS第一DP集合的抖动模式（DP）顺序地应用来执行抖动处理，并且执行抖动处理 通过相对于第二GC与第二帧相关联地将第二DP集合的DP顺序地应用于CIS。

    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.
