摘要： In the present invention, joint sections and non-joint sections are formed in nozzle arrays of a plurality of chips arranged in a print head. Correction values for correcting input image data are calculated for reducing color difference caused by variation in the ejection characteristics of the nozzles. In this calculation of correction values, first a first correction value corresponding to first nozzles that form a color measurement area is calculated based on the color measurement value obtained by measuring the color of a discrete color measurement area included in a patch formed by a nozzle array. Next, a second correction value for correcting input image data corresponding to second nozzles of the nozzle array is calculated based on the first correction value. Different complementary processing is used when calculating the second correction value corresponding to a non-joint section, and when calculating the second correction value corresponding to a joint section.

摘要： Provided are an image processing apparatus and an image processing method capable of reducing color unevenness due to variations in ejection characteristics among a plurality of nozzles when printing an image using a plurality of inks. To that end, a first image which is made up a color with noticeable color unevenness and similar colors is printed onto a print medium. The user then specifies a color and a nozzle position where color unevenness has occurred. On the basis of these results, parameters are set for a correction table referenced by are MCS processor. In so doing, it becomes possible to address the factor causing the color unevenness, and mitigate the effects of color unevenness in a focused way without incurring increases in processor load, memory requirements, or processing time as compared to the case of calibrating all lattice points.

摘要： Area information is obtained with respect to a specified color and nozzle position having color unevenness. Then, coordinate information indicating a nozzle position corresponding to the above area information is obtained in a printing head or nozzle array corresponding to an ink color relating to the specified color information. Next, the number of candidate correction values or candidate patches is obtained on the basis of nozzle coordinates obtained corresponding to the area, by referring to a table. In this table, for example, the number of candidate correction values is small at a nozzle position where an effect due to the variations of nozzle ejection characteristics such as a nozzle ejection volume is small and a change direction is constant, and the number of candidate correction values is large at a nozzle position where an effect due to variations of nozzle ejection characteristics is large.
