Abstract
The analysis and evaluation techniques of a gamut mapping technique, which can reflect the determination result of the quality of gamut mapping in the gamut mapping technique, are demanded. Hence, a color distribution information file and image file are loaded, initial 3D object data is generated based on color distribution data, and initial image object data is generated based on image data. The image object data and 3D object data are displayed on a monitor. When the user inputs a message, a process corresponding to the input message is executed, and the updated image object data and 3D object data are displayed on the monitor.
Claims16
A color information processing apparatus comprising:
- an acquisition section, arranged to acquire color image data, and color distribution information which indicates a relationship between sample point values in a first colorimetric system, and color coordinate values in a second colorimetric system;
- a constructor, arranged to construct surface information of a first three-dimensional object, on the basis of the color distribution information;
- a display section, arranged to display a first image based on the surface information, and a color image based on the input color image data;
- an input section, arranged to input a user's designation which designates a part of the displayed color image;
- and
- a generator, arranged to generate three-dimensional object data, representing a second three-dimensional object and based on color image data corresponding to the part of the color image designated by the user's designation,
- wherein said display section displays a second image corresponding to the second three-dimensional object superimposed on the first three-dimensional object.
A color information processing method comprising the steps of:
- acquiring color image data, and color distribution information which indicates a relationship between sample point values in a first colorimetric system, and color coordinate values in a second colorimetric system;
- constructing surface information of a first three-dimensional object on the basis of the color distribution information;
- displaying a first image based on the surface information, and a color image based on the input color image data;
- inputting a user's designation which designates a part of the displayed color image;
- and
- generating three-dimensional object data, representing a second three-dimensional object and based on color image data corresponding to the part of the color image designated by the user's designation,
- wherein the displaying step includes displaying a second image corresponding to the second three-dimensional object superimposed on the first three-dimensional object.
A computer program stored in a computer-readable storage medium, for a color information processing method, comprising process procedure code for:
- acquiring color image data, and color distribution information which indicates a relationship between sample point values in a first colorimetric system, and color coordinate values in a second colormetric system;
- constructing surface information of a first three-dimensional object on the basis of the color distribution information;
- displaying a first image based on the surface information, and a color image based on the input color image data;
- inputting a user's designation which designates a part of the displayed color image;
- and
- generating three-dimensional object data, representing a second three-dimensional object and based on color image data corresponding to the part of the color image designated by the user's designation,
- wherein the displaying process includes displaying a second image corresponding to the second three-dimensional object superimposed on the first three-dimensional object.
