ABSTRACT:
Method of, and apparatus for, processing a color coded character to recognize the character being examined by an OCR device. Said color coded character comprises a predominate color associated with said character distinguishable by humans, and a non-predominate color associated with said character and non-distracting to humans, but distinguishable by a color scanner. The present invention allows the non-predominate color of a character to be used as the sole criteria for recognizing the character.
