PURPOSE:To check automatically the misrecognition and to attain the automatic correction of the misrecognition if decided, by putting the check mark previously at the start and end points of each vector of an original drawing in an input mode of original pictures. CONSTITUTION:The check marks (circles, etc.) are put previously at the start and end points of each vector of an original drawing in an input mode of pictures. Then the original picture is supplied from a monochrome FAX 1 and the run length data is produced for each raster. The check mark is recognized as a symbol out of the produced data and the position of the symbol mark is stored in a picture memory 3 ad the coordinate data. Then the recognition processing is carried out based on the conventional graphic data obtained by separating the check mark out of the run length data. Based on the result of this recognition, a CPU 4 performs comparison and check. If the misrec ognition is decided, the error is corrected automatically. This shorten the draw ing correcting time. |
