Patent number: 8649026Abstract: A first identification number obtained by performing character recognition of each of a plurality of digits of an identification number and allocating predetermined characters to digits where characters cannot be determined and a second identification number representing an identification number that is the target of character recognition processing or search processing are compared with each other by calculating a matching ratio between the two numbers. When the matching ratio is lower than a predetermined reference value, a shifted identification number obtained by shifting each character forming the first identification number one digit in a predetermined direction and the second identification number are compared with each other by calculating a matching ratio between the two numbers. If this matching ratio is equal to or higher than the predetermined reference value, subsequent processing is continued, so that the shifted identification number is treated as the first identification number.Type: GrantFiled: February 21, 2012Date of Patent: February 11, 2014Assignee: Glory Ltd.Inventors: Takayuki Yamaguchi, Ryosuke Minami
