ABSTRACT:
A process for preparing discrimination criteria for color identification comprises reading values representing a plurality of color components delivered from a color sensor for each of a plurality of given reference colors, calculating relative values of the color components, calculating relative values of the color components, calculating the deviation of the relative value of each color component from a specified value, extracting pairs of deviations each having a discrimination distance of at least specified times relative to any other reference color, determining a discrimination criterion between the extracted pair of deviation, and repeating the extracting and determining steps by calculating deviations of higher order with use of the deviations until discrimination criteria are determined for all the given reference colors.
