Title: Character recognizing device
Inventor: SUZUKI KENJI
IPC: G06K9/68
Filed: 1993-03-15
Abstract: PURPOSE:To prevent wrong recognition when recognizing a character string mixing the different character types of characters. CONSTITUTION:In the case of dictionary data registration, the character type information of registration object characters discriminated by a character type discrimination part 213 based on the character codes of registration object characters and stored in a character type buffer 227 is changed by a character type change part 214 so as to show the externally designated character type. A user dictionary preparation part 216 registers the character codes of the registration object characters and dictionary data containing the pattern data for recognition of those characters in the registration area of a user correspondence character recognition dictionary 42 corresponding to the character type information in the buffer 227. Therefore, when recognizing the character string mixing the different character types of characters, the character types are unified, concerning the different character types of characters, the dictionary data changing them into the same character type are registered on the dictionary 42, and the recognition object is limited to the same character type. Thus, a character recognition part 212 performs recognition processing while referring to only the registration areas of a standard character recognition dictionary 41 and the dictionary 42 corresponding to the same character type.
