发明名称 COLOR CONVERTER
摘要 PROBLEM TO BE SOLVED: To attain color conversion with high accuracy in which color reproduction ranges between input output devices are preferably cross-refered by efficiently setting the output value of an image forming color image on an apex in an input color space in the color converter where the output value of the image is obtained by interpolating the output value set to an optional apex in the input color space divided into blocks. SOLUTION: Upon the receipt of information including the instruction of color conversion including compression processing in the direction of lightness and a type of paper forming an image by a CPU 307, a white reference/black reference correction section 309 references concerned data among received color image data based on plural white reference/black reference values stored in a white reference/black reference ROM 308 to execute linear conversion. The image data subjected to compression processing in the direction of lightness (luminance) are converted into color image data for image forming through an interpolation arithmetic operation by an interpolation processing section 302.
