PURPOSE:To obtain quickly a data made into a vectorial form and to facilitate coding of picture data and pattern recognition by generating vector in the highest-order segment out of registered segments from the coordinate relation of the lowest order segment. CONSTITUTION:A drawing 11 is photoelectrically converted by a photoelectrical conversion section 12 and binary coded by a binary coding device 13. The binary coded data is stored in buffer memories 18, 112. A run detecting section 110 detects run from the binary coded data, and a matching section 114 detects the number of runs of preceding line exists in the section corresponding to the run of detected line. A segment judging section examines to which segment a run is connected from the number of runs, and at the same time, stores the run with a segment table 115, segment length, inclination and line width, and registers whether the run exists in the segment or not. A vector generating section 118 generates vector from coordinate relation of the highest-order and the lowest- order segments out of registered segments. |
