Patent ID: 7142711

Claim:
An image processing method, comprising a step of carrying out a color conversion process in which first color image data composed of a first color system is converted to second color image data composed of a second color system, and when the first color image data is read image data which is obtained by reading a visible abject as an original image, the second color image data is set so as to be reproduced image data for fanning a reproduced image of the original image, wherein, the color conversion process is carried out in such a manner that, when the read image data includes data which is judged as memory color corresponding data, in order to obtain a reproduced image having colors substantially identical with colors of the original image, the reproduction image data is obtained using a transitional color conversion value which is a color conversion value in a color transition area formed in accordance with (i) a precise color conversion value for converting the read image data to the reproduced image data and (ii) a memory color conversion value for subjecting the read image data to a memory color conversion process, with respect to the memory color corresponding data, while the reproduced image data is obtained using the precise color conversion value, with respect to the read image data other than the memory color corresponding data.
