Patent ID: 7961974

Claim:
A liquid-crystal-driving image processing circuit that receives image data corresponding to voltages applied to a liquid crystal, the image data indicating gray-scale values of pixels in an image, corrects the image data according to changes in the gray-scale values of the pixels, and outputs the corrected image data, comprising: an encoding unit that encodes the image data representing a current frame of the image, thereby outputting encoded image data corresponding to the image in the current frame; a decoding unit that decodes the encoded image data, thereby outputting first decoded image data corresponding to the image data of the current frame; a delay unit that delays the encoded image data for an interval corresponding to one frame; a decoding unit that decodes the encoded image data output from the delay unit, thereby outputting second decoded image data corresponding to the image data one frame before the current frame; a preceding-frame image generating unit that generates preceding-frame image data by taking a difference between the first decoded image data and the second decoded image data for each pixel and selecting either the image data of the current frame or the second decoded image data according to the difference; and an image data correction unit that corrects the gray-scale values of the image in the current frame on the basis of the preceding-frame image data and the image data of the current frame.
