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.

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： A defect on the surface or in the surface layer of a moving material can be detected by using a method comprising steps of: heating the surface of the material, obtaining thermal image data of the surface of the material using an infrared thermography camera while the surface of the material is being heated up at the heating step or being cooled down after heating, and detecting the defect by calculating Laplacian with respect to temperature of the surface represented by the thermal image data. When the thermal image data is obtained while the material is being heated up, a heating device and the camera is arranged so that thermal energy emitted from the heating device is reflected by the material to come into the camera.
