Words possibly included in a scene image shot by a mobile camera can be efficiently extracted using a word dictionary or a map database. Positional information acquiring meansmeasures a current position of the device to acquire positional information. Directional information acquiring meansdetects a direction of the device to acquire directional information. Character recognizing meansdetermines a range of shooting of a scene image based on the current positional information and the directional information. The character recognizing meansextracts from a map databaseinformation such as store names, building names, and place names associated with positions in the shooting range. Then the character recognizing meansconducts character recognition using word knowledge such as the extracted store names, building names, and place names.
