Patent ID: 7623138

Claim:
A color information processing method of generating surface information of a three-dimensional object based on color information, comprising the steps of: inputting first color information and second color information, wherein each of the first color information and the second color information includes color data in a first color space and second color data in a second color space, and wherein for each of the first color information and the second color information, a correspondence is indicated for the first color data in the first color space to the second color data in the second color space; generating the surface information of the three-dimensional object in the second color space based on the first color information; comparing the first color data of the first color information relating to a polygon, which constructs the surface information, with the first color data of the second color information relating to the polygon; calculating color data of the polygon based on the comparison result; and outputting data for the three-dimensional object based on the generated surface information and the calculated color data of the polygon so as to display the three-dimensional object on a monitor.
