<p>PURPOSE:To improve a recognition factor by extracting plural strokes when detecting a curved part of a coupled black picture element group with an observation bearing code in the observation bearing, and one stroke at the time of no detection of the curved part. CONSTITUTION:The original of a document is scanned to read out density information and to binarize codes consisting of white and black. Subsequently, a raster scanning to execute the main scanning of a character pattern area from the left end to the right end and subscanning from the upper end to the lower end is performed. The state of a window consisting of 3X2 picture elements is observed while observing ''X''. In accordance with the pattern of the window state, a prescribed ID No. is assigned to the observation picture element X. Then, identification parameters IWRUM, BNDRY indicating the existence of the curved part are set up. When the parameters are executed for the character pattern, a different ID No. is assigned in each stroke, so that a black picture element having the same ID No. becomes one stroke.</p> |
