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.
