IMAGE PROCESSING APPARATUS AND METHOD FOR REDUCING POWER CONSUMPTION WITHOUT DETERIORATING IMAGE

摘要

An image processing apparatus and method for reducing power consumption without deteriorating image are provided to analyze image information by using a histogram, and change the luminance of an image and adjust the saturation of the image by using an image class in the location information on a frame of a pixel determined according to the analyzed result, thereby reducing the power consumption without the deterioration of the image. A histogram generator(101) generates a luminance histogram indicating the luminance distribution of an input image. A class determiner(102) determines one of plural classes on the basis of the generated luminance histogram. A luminance converter(103) increases the luminance of the input image in correspondence to the determined class. A power converter(104) sets the size of the driving power of an image processing apparatus at a low level in inverse proportion to an increase of the luminance.
