Character reader

Abstract

Abstract PURPOSE:To execute exactly at a high speed a recognition of a character-string by selecting a character-string containing a result of recognition and a proposed character whose similarity degree is high, from a word dictionary, deriving a similarity degree only with respect to this selected character-string, and recognizing the character-string. CONSTITUTION:A character-string of a business form 2 is scanned by a feature extracting means 1 of a character reader, and a feature of the character-string is extracted and provided to the first recognition means 3. By this recognition means 3, an input character is compared with a reference pattern of a recognition dictionary 4 which stores a feature of a reference pattern of a recognition object character, and a proposed character is derived and provided to the second recognition means 5. By this recognition means 5, a correct character-string is recognized by use of a character-string of a word dictionary 6 which stores a character-string of a recognition object, from a character-string of the inputted proposed character whose similarity is high. Subsequently, a character-string containing a proposed character whose similarity is high is selected, and only with respect to the selected character-string, the character-string is recognized by deriving its similarity degree, and a recognition in case when where are a lot of character-strings is executed at a high speed.
