Process for preparing discrimination criteria for a identifying colors for color identifying system
First Claim
1. In a color identifying system including a color sensor for detecting light from an object and delivering signals representing a plurality of color components, and a processing device for receiving the signals from the color sensor and for preparing therefrom color identifying discrimination criteria and for performing a color identifying process based on color component values represented by the signals, a process performed by said processing device for preparing said discrimination criteria, the process comprising the steps of:
- reading values representing a plurality of color components delivered from the color sensor for each of a plurality of given reference colors,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 deviations, andrepeating the extracting and determining steps by calculating deviations of higher order with use of lower order deviations until said discrimination criteria are determined for all the given reference colors.

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.
