    CPC classification number: G06T3/4084 ,  G06T3/40

    Abstract: An afterimage detection device includes a downscaling unit, an image accumulation unit, an afterimage detection unit and a weight applying unit. The downscaling unit downscales at least one input image at a preset ratio. The image accumulation unit receives at least one downscale image from the downscaling unit and accumulates the at least one downscale image. The afterimage detection unit detects an afterimage from an accumulated downscale image obtained by the image accumulation unit and generates afterimage information. The weight applying unit receives the afterimage information, calculates a downscaling weight of a region of interest including the afterimage in the input image based on a time parameter, and provides the downscaling weight to the downscaling unit. The weight applying unit may also or instead calculate and provide a luminance weight based on the time parameter.

    Abstract: An afterimage compensation device includes: an afterimage area detector to receive an input image, and detect an afterimage area including an afterimage in the input image; an afterimage area corrector to detect a false detection area, and generate a corrected afterimage area, the false detection area being a part of a general area that is not detected as the afterimage area and surrounded in a plurality of directions by the detected afterimage area; and a compensation data generator to adjust a luminance of the corrected afterimage area to generate compensation data.

    IPC: G09G3/30

    Abstract: A display device includes a display panel including a plurality of pixels, and a display driver, wherein the image includes at least one X-axis edge pattern in which a difference between gradation values of the two pixels adjacent to each other in an X-axis direction is equal to or greater than a reference gradation value difference, and at least one Y-axis edge pattern in which a difference between gradation values of the two pixels adjacent to each other in a Y-axis direction is equal to or greater than the reference gradation value difference, and degree of movement of some areas of the image in the X-axis direction is greater than degree of movement of some areas of the image in the Y-axis direction when the number of the X-axis edge patterns included in the image is larger than the number of the Y-axis edge patterns included in the image.
