ABSTRACT:
To equally assign processing to a plurality of processing units which perform drawing processing in parallel. The drawing data generating unit generates vectors from drawing data. The load estimated value calculating means obtains existence frequency of the vectors on each scan line as a load estimated value, and the processing responsibility range assignment unit assigns a drawing processing area within a page to each of the drawing processing units, on the basis of load estimated values and a reference value. The drawing data storage control unit transfers a vector required for drawing processing in a drawing processing area assigned to each of the drawing processing units to a corresponding drawing processing unit. Each of the drawing processing units performs drawing processing using the transferred vector. The processing result storage control unit synthesizes and outputs the results of drawing processing in the drawing processing unit.
