ABSTRACT:
Described herein is an apparatus for and a method of performing image-drawing processing on image-drawn objects such as at least characters or graphics with the image-drawn objects as an input. The apparatus comprises a list generating device that generates a list of image-drawn factor elements constituting the image-drawn objects, an image-drawn factor elements sorting device that classifies the image-drawn factor elements by use of reference values constant to information about the lengths of the image-drawn factor elements constituting the list, an image-drawn factor elements storing device that stores the classified image-drawn factor elements therein so as to correspond to the reference values, a plurality of image-drawing processing devices that perform parallel image-drawing processing on the image-drawn factor elements, an image-drawing area allocating device that divides an image drawing area into pieces and assigning the divided image-drawing areas to the image-drawing processing devices, an image-drawn factor elements transfer controlling device that transfers the image-drawn factor elements from the image-drawn factor elements storing device to said image-drawing processing device in association with the reference values, and a synthesizing and outputting device that synthesizes results of the image-drawing processing on the image-drawn factor elements by the image-drawing processing device and outputting the result of synthesis therefrom.
