PURPOSE:To segment complicatedly intricate character patterns accurately, by making it possible to segment character patterns from a pattern memory in the form of a polygonal line. CONSTITUTION:In case that character patterns are held in a pattern memory 2 and a character pattern, for example, ''4'' is cutout, a detection and cut conrol part 5 stores the column address in each line of the memory 2 for a predetermined cutting line (b) into an address memory 3 as the column address of the left side cutting line of the pattern ''4'' because no character pattern exists on the line (b). Meanwhile, since a character exists on a predetermined cutting line (c), the control part 5 determines a column address in every line of the right side cutting line of the pattern ''4'' to store it into an address memory 4. The lines (b) and (c) for the pattern ''4'' are obtained in this manner, and the pattern ''4'' existing in the region between these lines is cut out from the memory 2 and is transferred to a preprocessing part 6. |
