Patent ID: 8692942

Claim:
A data processing apparatus which corrects an image signal constituted by a plurality of pixel data that are externally supplied to an active matrix liquid crystal driving panel including a plurality of scanning signal lines that extend in one direction, a plurality of data signal lines that extend in another direction, and a plurality of pixels that are provided so as to correspond to respective intersections of the plurality of scanning signal lines and the plurality of data signal lines, the data processing apparatus, comprising: a correction processing section that (i) acquires pixel data of a first pixel for display of a first color component and pixel data of a second pixel for display of a second color component, the second pixel being driven by a scanning signal line which drives the first pixel and being driven by a data signal line which is adjacent to the first pixel, and (ii) corrects the pixel data of the second pixel in accordance with a relationship between a value of the pixel data of the first pixel and a value of the pixel data of the second pixel; and a correction amount memory section that stores correction amount data corresponding to a combination of the value of the pixel data of the first pixel and the value of the pixel data of the second pixel, the correction processing section carrying out the correction with reference to the correction amount memory section, wherein the correction processing section calculates a correction amount by carrying out interpolation calculation based on data stored in the correction amount memory section.
