Patent number: 11151373Abstract: An information processing apparatus includes processing circuitry. The circuitry acquires first ledger sheet definition information and second ledger sheet definition information from a memory. The first ledger sheet definition information defines relative positions of an item and a value of the item in a ledger sheet. The second ledger sheet definition information defines relative positions of an item and a value of the item in a ledger sheet unique to a user. Based on at least one of the first ledger sheet definition information and the second ledger sheet definition information, the circuitry extracts an item and a value of the item from reading result information that associates a character string read from a ledger sheet image with information representing a position of the character string, and the circuitry outputs the extracted item and value of the item as a recognition result.Type: GrantFiled: July 5, 2019Date of Patent: October 19, 2021Assignee: Ricoh Company, Ltd.Inventors: Yoshiharu Tojo, Toshifumi Yamaai, Koji Ishikura, Fumihiro Teshima
