PURPOSE:To improve a recognition rate by using a different kind character dictionary small in capacity by using a character hard to be recognized by a reference dictionary as a specific character to be registered on the different kind character dictionary. CONSTITUTION:A character recognition means 4 recognizes the character in word unit based on the reference dictionary by segmenting information in character unit from image information stored in a storage means 3 and extracting word information from the gap of segmented information in character unit. Also, a character re-recognition means 4 registers only the specific character out of the characters not being recognized by the character recognition means 4, and re-recognizes the character in word unit based on the different kind character dictionary. Therefore, it is possible to perform the segmentation of character information in alphabetic unit on the original of an English sentence first, and to recognize the character in word unit based on the information. Also, when character recognition is performed, the recognition is performed on the reference dictionary first, and the re-recognition of an unrecognized character is performed based on the different kind character dictionary on which only the specific character is registered. |
