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.
