发明名称 Data processing apparatus and data processing method
摘要 According to the invention it is possible to determine in advance whether it is possible to correctly generate a conversion table for calibration or color profile correction even with respect to an unknown print medium, and to avoid the preparation of unsuitable parameters and the performance of unsuitable image processing based thereon. In order to achieve this the color of a subject print medium is measured and from the color measurement result it is determined, based on color measurement data from a test pattern printed on the print medium, whether it is possible to obtain parameters suited to the print medium. As a result it has become possible to avoid the preparation of unsuitable parameters to be associated with the print medium, and it has become possible to output images with a comparatively stable reproduction of color even where performing printing on a variety of print mediums.

主权项 1. A data processing apparatus comprising: an obtaining unit configured to obtain a first measurement result by using a color measuring unit to measure a region of a subject print medium at which printing materials are not applied; and a determination unit configured to determine whether or not a second measurement result should be obtained, based on the first measurement result obtained by the obtaining unit, wherein a correction data corresponding to the subject print medium is generated based on the second measurement result which is obtained after the first measurement result is obtained by using the measuring unit to measure a region of the subject medium at which the printing materials are applied, and based on a target value corresponding to the region at which the printing materials are applied.
