PURPOSE:To execute the correction of an erroneous recognizing character with high accuracy by executing a morpheme analysis to all character strings to be prepared from a candidate character. CONSTITUTION:The input character read by an OCR part 1, after the similarity with a standard character for respective input characters by a character recognizing part 2 and a candidate character is obtained, is sent to a processing part 3. A post processing part 3 segments a word for a candidate character by referring to a word dictionary 10, a speech part classification table 11, a term application table 12 and a connecting weight matrix table 13, and executes the morpheme analysis by the connecting checking with a preceding word. The morpheme analysis is executed concerning all character strings of the unknown word which can be prepared from the candidate character of respective characters of the unknown word part, and executed by the processing to select the character string with the highest estimation value. Thus, when the deciding capacity of the erroneous recognizing character position is not high, the correcting capacity of the high erroneous recognizing character can be expected.
