Patent ID: 7545371

Claim:
A display device, comprising: a pixel array part having display elements provided inside of pixels formed in vicinity of cross points of signal lines and scanning lines aligned in matrix form; image capture circuits provided corresponding to said display elements, each including an optical sensor which picks up image at prescribed range of an imaging subject; an image capture processing unit which generates ultimate image capture data based on result of having picked up images a plurality of times while changing image capture condition except for display color, with respect to each of M kinds of display colors, and a color correction linear converter which performs matrix operation by using 3×3 matrix in which positive and negative signs of diagonal component and non-diagonal component are different from each other, with respect to a first color gradation signal, a second color gradation signal and a third color gradation signal outputted from said image capture circuit, wherein said image capture processing unit generates ultimate image capture data based on result of matrix operation by said color correction linear converter.
