ABSTRACT:
A color conversion system for optically scanning a target document or the like utilizing a monochromatic scanner connected to a computer is disclosed. The target is illuminated with a light source. The light is filtered from the light source to direct either red, green or blue frequency light to the scanner. The target is scanned three times, the scanner receiving red frequency light in a first scan, green frequency light in a second scan and blue frequency light in a third scan. The foregoing scans may occur in any order. In each of the scans, the light reflected from the target to the scanner is processed to generate corresponding red image data, green image data and blue image data. The red, green and blue image data is combined to generate multiple color image data. The multiple color image data may be displayed or printed to produce a multiple color image representative of the image on the target.
