A navigational information display system includes latitude-and-longitude information and image receiving unit which receives latitude and longitude information of active type electronic tags installed in real space, and receives an image of a real scene containing objects. This system further includes an image-and-object matching processing unit which separates an image of an object containing an object image of the surroundings of each electronic tag from the image of the real scene, and calculates a relative distance of each electronic tag and a position of the object on the image of the real scene; and an image-and-route matching processing unit which estimates a display position of a route to a destination set in advance on the image of the real scene to calculate a size of navigational symbol information on the basis of the latitude and longitude information of each electronic tag, information on the route to the destination, and the calculated position of the object. In this system, navigational information containing the navigational symbol information is superimposed on the image of the real scene and then displayed.
