PROBLEM TO BE SOLVED: To determine whether printing and colorimetry of a color chart are correctly performed. SOLUTION: A colorimetric value of other color patch is predicted from a colorimetric value of a partial color patch included in a colorimetric value group by clorimetry of the color chart (S802 and S803), and a color difference between the predicted colorimetric value and the colorimetric value of the other color patch included in the colorimetric value group is calculated (S804 and S806). Whether the printing and the colorimetry of the color chart are correctly performed, is determined based on the color difference (S807). COPYRIGHT: (C)2010,JPO&INPIT

Colorimetric values for generating a color separation table, which are obtained by measuring a plurality of color patches included in a color chart, are input, and measurement values corresponding to the input plural measurement values other than supervised input measurement values are estimated using supervised measurement values. Then, color differences between the estimated measurement values and the input plural measurement values other than the supervised measurement values are calculated. Based on the color differences, it is determined whether printing of the plurality of color patches or measurement of the plurality of color patches has been performed correctly.

Color processing apparatus and method for color processing using colorimetric data of a color chart

PROBLEM TO BE SOLVED: To re-sequence data without the need for remeasurement. SOLUTION: A system enables output, used for calibration of a document processing system(DPS), to be effective. Calibration target is termed for evaluating the range of output by the DPS. This target includes a plurality of target elements and element orientation information representing a physical layout of the target elements in the DPS output. The DPS output is generated, together with the calibration target. Characteristic values of the DPS output are measured in correspondence with individual target elements. When it is recognized that wrong sequencing has been performed for measurement of the target elements, the measurement values of the target elements of the DPS are re-sequenced, based on, a desired sequence for calculating an appropriate calibration function without the need for remeasurement.

PROBLEM TO BE SOLVED: To re-sequence data without requiring their re-measurements. SOLUTION: The outputs of the calibration systems used when performing calibrations to the document processing systems (DPS) are made effective. Each calibration target is generated for evaluating the range of the DPS output. The target includes a plurality of target elements and element orientation information for representing the physical layout of the target elements in the DPS output. The DPS output is generated together with the calibration targets. The characteristic values of the DPS output are measured correspondingly to the individual target elements. When recognizing the erroneous sequencing to the measurements of the target elements, the measurement values of the DPS target elements are re-sequenced based on the desired sequences for calculating proper calibration functions without requiring their re-measurements.
