To facilitate the management of a real image and also to expand the application range of real image data by setting and storing identification data that unequivocally specifies a photographic position of a camera camera, with associating the identification data with real image data sent from the digital camera and more over managing with organic association.

Map information a1 of a narrow area that includes concretely photographic position is called from ambient map information (a) which is stored in a storing means and includes a photographic arranged cite on a display device and graphically shown. Photographic position and direction are specifically designated from the map information a1 of the narrow area on the display device. Position data X and Y and angle data θ on the position map which are specifically designated on the display device are calculated, associated with real image data (b) that is acquired by a photographic unit and stored. Here, where each real image data (b) corresponds in the map information (a) is always managed.
