Abstract: Disclosed are an image processing circuit and image processing method which is capable of enhancing gray level presentation, and a display device using the same. The image processing circuit and image processing method performs a differential extension of each gray level to a higher gray level with respect to a perceived brightness picture level (PBPL) reflecting a distribution of high gray levels of the input image, and then overdrives a light emitting device in the region of high gray levels higher than or equal to the threshold gray level.

Abstract: A method and an apparatus for processing video data for display on a plasma display panel include dividing gray level values reverse gamma corrected with respect to input gray level values into an integer portion, an upper decimal fraction portion and a lower decimal fraction portion. The lower decimal fraction is then dithered, a first update value generated according to the lower decimal fraction dithering result is added to the upper decimal fraction portion, and the upper decimal fraction having the first update value added thereto is dithered. Finally, a second update value generated according to the upper decimal fraction dithering result is added to the integer portion.
