Abstract
In an image color estimation method, a signal value SG (Rs, Gs, Bs) is calculated based on a first display property and a tone value T (S), and an offset value Co (Ro, Go, Bo) that corresponds to the respective components (Rs, Gs, Bs) in the signal value SG is calculated based on the first display property P, a second display property P, and the tone value T (R, G, B) (S). Then, a correction signal value SC (Rc, Gc, Bc) is calculated by adding the offset value Co (Ro, Go, Bo) to the signal value SG (Rs, Gs, Bs) (S). The correction signal value SC (Rc, Gc, Bc) is converted into a correction signal value ST (Xc, Yc, Zc) using a conversion matrix M (S).
