专利汇可以提供Graphic processing unit专利检索,专利查询,专利分析的服务。并且PURPOSE: To eliminate noise and to correct a blurred part by synthesizing two patterns obtained by binary-coding a multi-value pattern obtained from the optical scanning with two different threshold values.
CONSTITUTION: The multi-value signal (m) of a character pattern obtained from a photoelectric converting section and scanned is binary-coded at quantization circuits 10, 11 as binary-coding means set with two different threshold values and the result is stored in pattern memories 12, 13 respectively. The two character patterns are fed to a pattern synthesis circuit 14, where the patterns are synthesized by deciding one picture element bit depending on adjacent 8-bit, resulting that a character pattern without noise or blur is obtained and stored in a pattern memory 15.
