Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
183 words
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, and repeating 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.
Claim 2
Dependent Claim
183 words
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, and repeating 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.
Claim 3
Dependent Claim
64 words
A process as defined in claim 1 which comprises: extracting the relative values having a discrimination distance of at least specified times relative to any other reference color, determining a discrimination criterion between a pair of extacted relative values, and performing the step of calculating the deviation to establish discrimination criteria for the reference colors for which the discrimination criteria have not been determined.
Claim 4
Dependent Claim
52 words
A process as defined in claim 1 wherein when there are positive and negative deviation values for one color component, the deviation values are classified into a positive group and a negative group, and pairs of deviation values having a discrimination distance of at least specified times are extracted for each group.
Claim 5
Dependent Claim
18 words
A process as defined in claim 1, wherein said at least specified times is at least two times.
Claim 6
Dependent Claim
131 words
A color identifying system for automatically preparing discrimination criteria for color identification comprising: a color sensor for detecting light from an object and delivering signals representing a plurality of color components, means for calculating relative values of the color components from the signals from the color sensor, means for calculating the deviation of the relative value of each color component from a specified value, means for extracting pairs of deviations each having a discrimination distance of at least specified times relative to any other reference color, means for determining a discrimination criterion between the extracted pair of deviation, and control means for repeating the extracting and determing procedures by calculating deviations of higher order with use of lower order deviations until discrimination criteria are determined for all the given reference colors.
Claim 7
Dependent Claim
131 words
A color identifying system for automatically preparing discrimination criteria for color identification comprising: a color sensor for detecting light from an object and delivering signals representing a plurality of color components, means for calculating relative values of the color components from the signals from the color sensor, means for calculating the deviation of the relative value of each color component from a specified value, means for extracting pairs of deviations each having a discrimination distance of at least specified times relative to any other reference color, means for determining a discrimination criterion between the extracted pair of deviation, and control means for repeating the extracting and determing procedures by calculating deviations of higher order with use of lower order deviations until discrimination criteria are determined for all the given reference colors.
Claim 8
Dependent Claim
70 words
A system as defined in claim 5 which comprises: means for extracting the relative values having a discrimination distance of at least specified times relative to any other reference color, means for determining a discrimination criterion between a pair of extracted relative values, and control means for permitting the calculation of the deviation to establish discrimination criteria for the reference colors for which the discrimination criteria have not been determined.
Claim 9
Dependent Claim
52 words
A system as defined in claim 5 wherein when there are positive and negative deviation values for one color component, said extracting means classifies deviation values into a positive group and a negative group and extracts pairs of deviation values having a discrimination distance of at least specified times for each group.
Claim 10
Dependent Claim
18 words
A system as defined in claim 5, wherein said at least specified times is at least two times.
