Patent ID: 7250956

Claim:
A color image processing apparatus, comprising: color look-up table (CLUT) synthesis ON/OFF determining means for determining whether or not a single synthesized CLUT is generated by synthesizing a plurality of CLUTs with respect to a plurality of CLUT groups which are sequentially referred at a time of carrying out color conversion on a drawing object, for each drawing object which is a component of text data, on the basis of attribute information of the drawing object; CLUT synthesis ON/OFF storing means for storing determined results determined by the synthesis ON/OFF determining means; CLUT synthesizing means for generating the single synthesized CLUT by carrying out CLUT synthesis at the time when the determination by the synthesis ON/OFF determining means is varied from OFF to ON; synthesized CLUT storing means for storing the synthesized CLUT which is a result that arbitrary CLUTs among said plurality of CLUT groups are synthesized by the CLUT synthesizing means; and color conversion means for carrying out color conversion with respect to an arbitrary drawing object on the basis of the attribute information of the drawing object and the stored contents of the CLUT synthesis ON/OFF storing means, with reference to CLUTs to be applied to the drawing object from one of the synthesized CLUT and a predetermined CLUT among said plurality of CLUT groups.
