PURPOSE: To enable quantization free from a character fluctuation and an inclination by extracting a temporary segment from inputted coordinate information and by considering the synthesization of adjacent temporary segments as one temporary segment if the difference in the temporary directional code of the adjacent temporary segments.
CONSTITUTION: Coordinate information (a) obtained from a coordinate input device 1 is inputted to a temporary segmenting processing part 2, a candidate considered to be the segment is extracted and set to temporary segment information (b), which is inputted to a temporary directional code generating part 3. In accordance with the direction of the temporary segment, temporary directional code information (c) in 32 directions is generated and inputted to a segment synthesization processing part 4, which synthesizes the segment if necessary by utilizing the temporary directional code information (c) and outputs the final segment information (d). A directional code generating part 5 outputs directional code information (e) in eight objective directions in accordance with the direction of the segment. Provided that when directional codes of adjacent two segments are equal, they are synthesized in order to be one line segment, and one directional code shall be given.
