1. A curve division device for use in producing an outline font, said curve division device comprising: a plurality of processor elements; a reception unit receiving input data of curve information and distributing the curve information to each of the processor elements; a program storage unit; and an execution unit causing each of the processor elements to execute a plurality of programs stored in the program storage unit, wherein the programs stored in the program storage unit include a rough division program and a segment determination program, the rough division program and the segment determination program are executed by each of the processor elements, the rough division program involves generating two divided curves by dividing a curve indicated by the curve information in the input data, selecting one of the two divided curves in accordance with a value of a specified digit in a processor element ID, and repeating the generation of the two divided curves, a shift of the digit in the processor element ID, and the selection of the divided curve until the divided curve selected by each of the processor elements is different, the segment determination program includes a segment number determination program and a fine division program, the segment number determination program involves determining, for each of the divided curves ultimately selected as a result of executing the rough division program, a number of divisions of a given divided curve according to a degree of curvature of the divided curve, and the fine division program involves re-dividing the given divided curve in accordance with the number of divisions determined according to the degree of curvature, and approximating each line segment obtained by the re-dividing, wherein each line segment obtained by the re-dividing is used to produce the outline font.
