There is provided a navigation apparatus which displays information concerning facilities or the like which are present in a broad range ahead of a user. An information processing section 4 of a navigation apparatus identifies a facility type to be displayed. Next, a predicted road along which a user is expected to travel is determined, and a reference intersection is selected from among the intersections on the predicted road. The information processing section 4 computes a network of roads beginning from the selected reference intersection, and acquires facility information in the neighborhood thereof. Furthermore, the information processing section 4 generates facility information image data for displaying the acquired facility information on a map.

1. Field of the Invention
The present invention relates to a navigation apparatus, and more particularly to a navigation apparatus which displays a map together with information concerning facilities and the like around a user's location.
2. Description of the Background Art
FIG. 1 is a block diagram illustrating the structure of a navigation apparatus according to a first embodiment of the present invention;
FIG. 2 is a flowchart illustrating a processing procedure by an information processing section 4 shown in FIG. 1 as described in a program to be executed by the information processing section 4;
FIG. 3 is a flowchart illustrating the details of step S104 in FIG. 2;
FIG. 1 is a block diagram illustrating the structure of a navigation apparatus according to a first embodiment of the present invention. Although it is assumed that the navigation apparatus according to the first embodiment is to be used in a vehicle (e.g., an automobile), in other embodiments, the present navigation apparatus is not limited to the use in vehicles. In FIG. 1, the navigation apparatus comprises an input section 1, a moving state detection section 2, a communication section 3, an information processing section 4, a history storage section 5, a map data storage section 6, an output section 7, and a status information acquisition section 8. Hereinafter, the respective sections of the navigation apparatus will be described.
A user operates the input section 1, which is composed of a crosskey pad, a mouse, a keyboard, and/or the like, for inputting information which is set by the user. The details of the information which is set by the user will be described later with reference to an operation of the present navigation apparatus. The information which has been input via the input section 1 is outputted to the information processing section 4.
The moving state detection section 2, which is typically composed of receiver, a gyrocompass, and a velocity sensor for the GPS (Global Positioning System), detects a current location and a traveling direction of the vehicle (user), and generates current location information representing the coordinates of the current location and information representing the traveling direction. The generated information is outputted to the information processing section 4.
