ABSTRACT:
An image scanning system for producing an electronic version of a hardcopy element which is compensated for spectral content of an illumination source in the image scanning system, the image scanning system includes a sensor for receiving light containing the hardcopy element for forming and storing an electronic version of the hardcopy element; a spectral sensor for receiving light from the illumination source and storing an electronic version of spectral contents of the illumination source; and a conversion system for receiving the electronic versions of the illumination source and the hardcopy element and creating a compensation table that compensates subsequent hardcopy elements passed through the conversion system.
