Abstract
A contrast control apparatus includes a memory for storing input image signals within one frame and an image reducing unit for selecting at least one image signal of the input image signals. An accumulation value calculating unit calculates accumulation values for predetermined sampling gray values with respect to the selected image signal. An image characteristic decision unit determines at least one characteristic of the selected image based on the accumulation values. A contrast control function calculating unit calculates a contrast control function based on the characteristic of the selected image. A contrast controller controls contrast of the image signals stored in the memory according to the contrast control function.
