Patent ID: 7345713

Claim:
A video display apparatus which displays a video image based on a video signal in a video display portion comprising a plurality of pixels, comprising: a video signal conversion portion which converts the video signal into a digital video signal consisting of N bits (N is an integer) and outputs the converted signal; a correction data storage portion which stores correction data consisting of P bits (P is an integer) with respect to a pixel having a light emission luminance exceeding a predetermined threshold value in the video display portion; a data interpolation portion which receives the correction data stored in the correction data storage portion, interpolates the correction data in data consisting of M bits (M is an integer), and provides interpolation data; and a video signal output portion which outputs a video signal consisting of L bits (L is an integer) with which a difference in characteristics between display pixels in the video display portion is corrected, based on the video signal consisting of N bits output from the video signal conversion portion and the correction data consisting of M bits output from the data interpolation portion, wherein the data interpolation portion assigns the correction data consisting of P bits to a selected position in M bit positions of the interpolation data, the selected position determining a range and an accuracy of correction and being set in accordance with characteristics of the video display portion.
