PROBLEM TO BE SOLVED: To provide a color conversion method, a tone value correction device, a computer program and a display device, capable of reproducing fine tone change between grid points, with the suppression of accuracy deterioration produced by interpolation.SOLUTION: A second conversion unit sections one of an input tone and an output tone, having tone characteristics indicative of input/output tone characteristics to be reproduced, into tone sections having predetermined tone intervals. Each tone value of another tone of the tone characteristics is corrected on the basis of each tone section, in such a manner that the intervals of another tone of the sectioned tone sections become intervals corresponding to the predetermined tone intervals. A first conversion unit converts each tone value of the image using each corrected tone values. |
