Patent ID: 7327340

Claim:
An image data processor for a liquid-crystal display that generates image data determining voltages applied to a liquid crystal from gray-scale values of an input image made up of a series of frames, the image processor comprising: an encoding unit for encoding an input image data of a present frame and outputting an encoded image data; a first decoding unit for decoding the encoded image data and outputting a first decoded image data corresponding to the present frame; a delay unit for delaying the encoded image data for an interval corresponding to one frame and outputting a delayed encoded image data; a second decoding unit for decoding the delayed encoded image data and outputting a second decoded image data corresponding to a previous frame; a compensation data generator for generating compensation data for adjusting the gray-scale values of the present frame according to the first decoded image data and the second decoded image data; and a compensation unit for generating said image data according to the input image data and the compensation data.
