Title IMAGE COLOR ESTIMATION METHOD, IMAGE COLOR ESTIMATION DEVICE, AND IMAGE COLOR ESTIMATION PROGRAM
Abstract Provided is an image color estimation method that: calculates a signal value (SG) (Rs, Gs, Bs) based on a first display characteristic and a gradation value (T) (S121); and calculates an offset value (Co)(Ro, Go, Bo) corresponding to each component (Rs, Gs, Bs) of the signal value (SG), based on the first display characteristic (P1), a second display characteristic (P2), and the gradation value (T) (R, G, B) (S122); then adds the offset value (Co)(Ro, Go, Bo) to the signal value (SG) (Rs, Gs, Bs), and calculates the correction signal value (SC) (Rc, Gc, Bc)(S123); and converts the correction signal value (SC) (Rc, Gc, Bc) to a correction signal value (ST)(Xc, Yc, Zc) using a conversion matrix (M)(S124).
