Abstract: A method of image processing includes extracting first image information from an input image by analyzing the input image, determining, based on the first image information, whether to utilize a high dynamic range (HDR) function for the input image, setting an image output mode based on a result of the determination, setting a reference tone curve for the input image based on the image output mode, and generating an output image by converting the input image based on the reference tone curve.

Abstract: A display device includes a display panel and a display image shift controller. The display panel includes a display area in which a display image is displayed and a shift area located within the display area. The display image shift controller generates a route shift signal, where a reference point of the display image is shifted in the shift area based on the route shift signal. The route shift signal includes first and second routes corresponding to a path through which the reference point of the display image is shifted. The first route includes a first sub-route and a second sub-route. The second route includes a third sub-route and a fourth sub-route. The first, second, third, and fourth sub-routes are different from each other.

Abstract: A display device includes an image analyzing part which determines whether current frame image data includes a crosstalk pattern, and a gamma voltage generator which generates current frame gamma data by applying the asymmetric gamma when the current frame image data do not include the crosstalk pattern, and generates the current frame gamma data by applying a symmetric gamma when the current frame image data includes the crosstalk pattern. The positive polarity and negative polarity data voltages of the asymmetric gamma are asymmetric with each other for each of the grayscales, and the positive polarity and negative polarity data voltages of the symmetric gamma are symmetric with each other for each of the grayscales.
