摘要： A separating position candidate detecting unit 21 detects separating position candidates in a character row derived by a character row deriving unit 11. A character candidate separating unit 31 separates character candidates by using the separating position candidates obtained by the separating position candidate detecting unit 21. A newly provided separation shape determining unit 32 determines separation shapes at the same time. A character recognition unit 41 provides a character kind and separation shape of a reference pattern most resembling each separation shape by using a character recognition dictionary 42, in which reference patterns are stored each for each separation shape. A recognition result verifying unit 51 checks character recognition results character candidate patterns provided from the character recognition unit 41 and corresponding separation shapes with reference to a verification rule memory unit 52, in which right recognition result/separation shape combinations allowable to be provided are stored. A pertinent combination is provided as a recognition result. Otherwise, the operation is repeated by deriving a character candidate pattern and the corresponding separation shape by using a different separating position candidate.
