11. A mobile terminal device for communicating information with a fixed station device and executing character recognition processing to recognize a character or a character string included in an image, comprising: imaging means for shooting an image; position measuring means for measuring a shooting position of an image to obtain shooting position information indicating the shooting position; direction detecting means for detecting a shooting direction of an image to obtain shooting direction information indicating the shooting direction; information transmitting means on mobile terminal side for transmitting the shooting position information and the shooting direction information via a communication network to the fixed station device; information receiving means on mobile terminal side for receiving from the fixed station device non-corresponding-to-position information that is words not associated with respective positional information indicating positions of respective places and that is determined by the fixed station device using the shooting position information and the shooting direction information; and character recognizing means for recognizing a character or a character string included in the image imaged by the imaging means, using the non-corresponding-to-position information received by the information receiving means on mobile terminal side.
