Abstract:
A method of converting first color data contained in a first non-standard and device-dependent color range of a first image device into second color data contained in a second non-standard and device-dependent color range of a second image device, comprising the steps of:classifying said first color data into a corresponding color data in a device-independent standard color space and a corresponding color defined according to human color perception of said first color data in said device-independent standard color space by referring to a classification table representing the correspondence between colors determined based on said human color perception in said device-independent standard color space and said corresponding color data; and converting said corresponding color data into a standard color data of said second device-dependent color range in said device-independent standard color space with respect to each of the classified colors, and converting said standard color data into said second color data of a second non-standard and device-dependent color range of said second image device.
