Abstract: A method of compensating an image to be display on a display panel is disclosed. In one aspect, the method includes receiving a first input image and adjusting a contrast sensitivity of the first input image. The method also includes calculating a first derivative of luminance of a pixel included in the adjusted image, calculating a second derivative of the luminance of the pixel, and accumulating the first and second derivatives. The method further includes determining a burn-in causing boundary based at least in part on the accumulated first and second derivatives, receiving a second input image, and comparing the burn-in causing boundary to a boundary of the second input image to determine whether to apply burn-in compensation. The method finally includes compensating a portion of the second input image corresponding to the burn-in causing boundary based at least in part on an unsharpening filter.

Abstract: A method of image processing includes determining a supplement pixel and original pixels adjacent to the supplement pixel, deriving luminance data of the original pixels from input image data, calculating a difference value among the luminance data of the original pixels, selecting an original pixel of the original pixels as an effective pixel when the difference value of luminance data of the original pixel and a nearest original pixel to the supplement pixel is smaller than a predetermined threshold value, setting a weighted value of the effective pixel based on a distance between the supplement pixel and the effective pixel, and calculating luminance data of the supplement pixel based on luminance data of the effective pixel and the weighted value.
