PROBLEM TO BE SOLVED: To efficiently perform reliable address recognition with high accuracy.;SOLUTION: In this address recognition device, address recognition method and address recognition program, address recognition processing includes character separation processing, key character extraction processing, lump-sum place name recognition processing, and address determination processing. The key character extraction processing extracts a key character from a plurality of single character areas. The key character extraction processing to each of the single character areas includes: characteristic vector extraction processing extracting a characteristic vector from an image corresponding to the single character area; collation processing collating the characteristic vector extracted by the characteristic vector extraction processing and a characteristic vector of the key character in a key character dictionary storing all the possible key characters, and retrieving all possible key character candidates; and key character path determination processing determining a rightful key character path when recognizing the plurality of single character areas each having at least one key character candidate retrieved by the collation processing.;COPYRIGHT: (C)2007,JPO&INPIT
