1. An image-drawing processing apparatus for performing image-drawing processing on image-drawn object or image-drawn objects such as at least characters or graphics with the image-drawn objects as an input, comprising: list generating means for generating a list of image-drawn factor elements constituting said image-drawn objects; image-drawn factor elements sorting means for classifying said image-drawn factor elements by use of reference values constant to information about the lengths of said image-drawn factor elements constituting said list; image-drawn factor elements storing means for storing said classified image-drawn factor elements therein so as to correspond to said reference values; a plurality of image-drawing processing means for performing parallel image-drawing processing on said image-drawn factor elements; image-drawing area allocating means for dividing an image-drawing area and assigning the divided image-drawing areas to said image-drawing processing means; image-drawn factor elements transfer controlling means for transferring said image-drawn factor elements necessary for image-drawing processing of said image-drawing area from said image-drawn factor elements storing means to said image-drawing processing means in association with said reference values; and synthesizing and outputting means for synthesizing results of the image-drawing processing on the image-drawn factor elements by said image-drawing processing means and outputting the result of synthesis therefrom.
