PROBLEM TO BE SOLVED: To precisely realize color processing corresponding to the attribute of an object by executing color processing for an image with respect to the object when logical arithmetic is judged to be the copy of a bit map when the attribute of the object is judged to be the image. SOLUTION: At a step 8-1, a driver receives a plotting instruction sent from an OS and at a step 8-2, the attribute of which object the plotting is instructed is judged from the form of the plotting instruction. When the object attribute is the plotting instruction to an image, whether an object shown by the plotting instruction is suited to color correction for imaging is judged. Namely, whether logical arithmetic in the plotting instruction is for copying a source bit map or a pattern bit map is judged at a step 8-3. When it is judged to be for copying and the number of colors is judged to be equal to or larger than 256 at a step 8-4, color processing for imaging is executed to a bit map delivered with the plotting instruction at a step 8-10. |
