ABSTRACT:
A color processing method utilizing a plurality of devices having different color spaces as one virtual device. A scanner inquires a computer of color space and presence/absence of a color conversion function. If the computer has the color space conversion function, the scanner transmits color image data with parameters for converting the data into data of the color space of the computer. Inversely, the computer inquires the printer of color space and presence/absence of a color space conversion function. If the printer has the color space conversion function, the computer transmits color image data with parameters obtained from operation of parameters for converting the color space of the image data into the color space of the printer and the parameters received from the scanner.
