Abstract:
1. An image processing method for performing color process on an input image based on a color appearance model, said method comprising the steps of: inputting a manual instruction of a user, which relates to conditions for respectively adjusting (1) balance, and (2) absolute intensity, of a chromatic adaptability; inputting a manual instruction of the user, which relates to viewing conditions of respectively an image input side and an image output side; setting a parameter of the chromatic adaptability from the inputted balance and absolute intensity; performing a forward conversion of the color appearance model to convert color data of the input image into color data independent of any viewing condition by using the viewing condition of the image input side and the set parameter; and performing an inverse conversion of the color appearance model to convert the color data obtained in the forward conversion into color data dependent of the viewing condition of the image output side by using the viewing condition of the image output side and the set parameter.
