Claim 20:
21. An information processing method comprising:
a photograph reception step of receiving a captured map photograph from a terminal device;
a determination step of searching a navigation information group that contains two or more pieces of navigation information that contain map representation data and two or more pieces of correspondence information that are each a set of coordinate information and position information on the map representation data that is one of an illustration map, a handwritten map, and a sketch map, and determining a piece of navigation information that has a relationship that satisfies a first condition, with the map photograph; and
a navigation information transmission step of transmitting the piece of navigation information determined in the determination step, to the terminal device, wherein:
the photograph reception step includes additionally receiving terminal position information that specifies the current position of the terminal device,
the information processing method further comprises:
a string acquisition step of acquiring three or more strings from the map photograph;
a coordinate information acquisition step of acquiring pieces of coordinate information regarding the three or more strings;
a position information acquisition step of acquiring pieces of position information corresponding to the three or more strings, using a location dictionary that contains one or more pieces of location position information that associate pieces of location information that specify locations and pieces of position information that specify positions of the locations with each other; and
a current coordinate acquisition step of acquiring current coordinate information that specifies coordinates corresponding to the terminal position information, using three or more pieces of correspondence information that are sets of the pieces of coordinate information and the pieces of position information, and the terminal position information, and

the navigation information transmission step of transmitting the current coordinate information to the terminal device instead of the piece of navigation information.
