Abstract:
1. A method of performing spatial color matching that converts an image of an input side under input viewing conditions into an image of an output side under output viewing conditions, which is carried out in an information processing apparatus, the method comprising the steps of: forward-converting the image of the input side into an image in a color appearance space of a human based on the input viewing conditions including parameters, which are used to determine field sizes of an input image based on a viewing angle; converting the image in the color appearance space into an image in the color appearance space within a color reproduction range of an output device by gamut mapping according to the color reproduction range of the output device; and inversely converting the image in the color appearance space within the color reproduction range of the output device into the image of the output side based on the output viewing conditions including parameters, which are used to determine field sizes of an output image based on a viewing angle.
