CHARACTER SORTING METHOD

PURPOSE:To sort accurately stroke data into character and pattern data by deciding a character when the length of strokes of the handwritten pattern and character is smaller than the prescribed value and otherwise deciding a pattern respectively. CONSTITUTION:The movements of a pen (pen-down through pen-up) on a tablet 1 are sampled every fixed period of time. Thus the time series data on the pen coordinate value is obtained and stored to a stroke memory 2 and to a storke length detector 3. The detector 3 calculates the stroke length Ll continuous until a pen-up signal is detected and input it to a stroke length decider 4. The decider 4 compares the length Ll with the value Lc of a character stroke threshold value ROM5. Then the pattern data is decided when the Ll is larger than the Lc. A control signal is outputted to a stroke data switch 6, and the time series data stored in the memory 2 are sorted into the character and pattern strokes and delevered.
