Image processing system capable of attaining color coincidence between input and output images

An image processing system having an image input device that produces first image information on a first, arbitrary color space, comprising:

• means for recognizing the first color space and, if it is not a standard color space, whether the first image information is associated with color correction data to be used for conversion to the standard color space;
• means for storing a plurality of color correction data to be used for conversion to the standard color space;
• means for designating an image output device;
• means for converting the first image information not on the standard color space to second image information on the standard color space using the color correction data associated with the first image information, and for converting the first image information neither on the standard color space nor associated with color correction data to second image information on the standard color space using corresponding one of the color correction data stored in the storing means, in accordance with the recognized first color space and a color space of the designated image output device;
• and
• means for sending the first or second image information on the standard color space to the designated image output device.

An image processing system for processing first image information on a first, arbitrary color space sent from an image input device, comprising:

• means for recognizing the first color space and, if it is not a standard color space, whether the first image information is associated with color correction data to be used for conversion to the standard color space;
• means for storing a plurality of color correction data to be used for conversion to the standard color space;
• and
• means for converting the first image information not on the standard color space to second image information on the standard color space using the color correction data associated with the first image information, and for converting the first image information neither on the standard color space nor associated with color correction data to second image information on the standard color space using corresponding one of the color correction data stored in the storing means, in accordance with the recognized first color space and a color space of the image processing system.
