PROBLEM TO BE SOLVED: To provide an image display device capable of reliably increasing the brightness.SOLUTION: The product of a matrix of additive mixture of colors and a matrix of signals (R, G, B) is multiplied by a purity coefficient Ψ to obtain a tristimulus value. Then, assuming that the all the values of signals (R, G, B) are at min (R, G, B), another tristimulus value is obtained from the product of the matrix of additive mixture of colors and the matrix of signals (R, G, B). On the basis of the difference between the tristimulus values, which is obtained by subtracting the latter tristimulus values from the former one, and the inverse matrix of the product of the matrix of additive mixture of colors multiplied by TH, the values of signals (R, G, B) are determined and value of a signal Wis determined as value of min (R, G, B). |
