PROBLEM TO BE SOLVED: To provide a technique by which, in a display device, a correction coefficient for correcting deviation between a virtual color in a case where an ideal additive color mixture is established, and an actual display color in the display device can be accurately estimated.SOLUTION: A correction coefficient calculation device according to the present invention includes estimation means for estimating a correction coefficient for a second color mixture image signal from a correction coefficient for a plurality of first color mixture image signals; wherein when a pixel of the display device has a structure in which a subpixel of a second fundamental color, which is different from a first fundamental color, is disposed adjacent to a subpixel of the first fundamental color on one side thereof, the estimation means acquires a correction coefficient for the first fundamental color of the second color mixture image signal by adding modification by the difference in the gradation value of the second fundamental color between the first color mixture image signal and the second color mixture image signal, to a correction coefficient to the first fundamental color of the first color mixture image signal whose gradation value is the same as that of the second color mixture image signal. |
