PROBLEM TO BE SOLVED: To perform image processing with efficiency by processing an object image according to which of a black-and-white image, a color image having more than a specific number of colors, and a color image having less than the specific number of colors the object image is. SOLUTION: The image processing is performed according to which of the black-and-white image, the image having more than the specific number of colors, and the image having less than the specific number of colors the object image is. A host computer 9 obtains a drawing instruction from an application program 1 and stores it in a spool file 6, and also counts colors and generates a color table 5. A color number counter 4 counts the colors in the image and the color table 5 contains the input color image and indexes so that they correspond to each other. Then, transfer processing is performed. Here, image data corresponding to the drawing instruction in the spool file 6 are expanded on a screen through processing corresponding to the number of the colors, color processing is carried out, and the result is transferred to a printer 8. This processing is repeated for all image data. |
