Patent ID: 8654118

Claim:
A color-information processing method for displaying a three-dimensional object of color distribution, said method comprising performing the following steps by a processor: (a) a color-distribution-information input step of inputting color-distribution-information which indicates second color coordinate data in a second color system, each of the second color coordinate data corresponding to first color coordinate data in a first color system; (b) a viewpoint information setting step of setting viewpoint information according to a user instruction; (c) a range setting step of setting a range in the first color system as a boundary of the three-dimensional object of color distribution to be displayed according to a user instruction; (d) a step of selecting first color surface data corresponding to the set range in the first color system and obtaining, based on the color-distribution-information, second color surface data corresponding to the selected first color surface data; (e) a determination step of determining display surface information of the three-dimensional object based on second color surface data and determining display color information of the surface of the three-dimensional object based on the second color surface data; and (f) a display step of displaying the three-dimensional object of color distribution corresponding to the viewpoint information based on the display surface information of the three-dimensional-object and the display color information of the surface.
