Abstract

PURPOSE:To improve the accuracy of character recognition difficult for correct recognition with the discrimination of similarity in character unit, by discriminating the similarity through a plurality of character sets or words as the unit. CONSTITUTION:A characteristic parameter of an unknown character pattern picked up at a characteristic pickup section 12 is inputted to similarity discriminating sections 13 and 14 respectively. The section 13 checks the similarity of the characteristic parameters between the known character pattern registrated in a dictionary file 15 and the unknown character pattern and outputs the character code of the character pattern with the highest similarity. The other similarity discriminating section 14 the similarity between the characteristics parameters of a known non-separable pattern registrated in other dictionary file 16 and that inputted from the section 12 and outputs the character code of non- separable pattern with the highest similarity. A final discriminating section 17 outputs a dictionary code outputted from the section 13 as the result of final recognition when the similarity discriminated as the highest at the section 13 is higher than the specified similarity.
