IMAGE PROCESSOR AND IMAGE FORMING APPARATUS PROVIDED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an image processor for reducing a data storage amount to carry out color correction processing without the need for revision of an interpolation method and complicated address calculation. SOLUTION: The image processor is provided with a color conversion section 201 for applying color conversion processing of RGB image data into CMY image data. The color conversion section 201 is provided with a three-dimensional LUT 401 of storing CMY image data corresponding to each grating point included in a plurality of R-B planar regions perpendicular to a G axis in an RGB space split in a grating form and carries out color conversion processing on the basis of the CMY image data stored in the three-dimensional LUT 401. Further, a plurality of the R-B planar regions are not uniformly sized. COPYRIGHT: (C)2005,JPO&NCIPI
