Abstract

A navigation apparatus displays information required reaching a destination on a display screen to guide a vehicle to the destination. The navigation apparatus includes first and second display control units. The first display control unit displays at least a part of a route to the destination on the display screen. The first display control unit also displays each of main points on the route as a mark on the display screen. The second display control unit determines whether or not a user selects one of the main points. The second display control unit also displays a real image showing surrounding of the selected main point on the display screen on the basis of position information of the selected main point and real image data corresponding to position coordinates, when the second display control unit determines that the user selects one of the main points.

Claims

1. A navigation apparatus for displaying information required reaching a destination on a display screen to guide a vehicle to the destination, the navigation apparatus comprising:

a first display control unit for displaying at least a part of a route to the destination on the display screen and displaying each of main points on the route as a mark on the display screen; and

a second display control unit for determining whether or not a user selects one of the main points and displaying a real image showing surrounding of the selected main point on the display screen on the basis of position information of the selected main point and real image data corresponding to position coordinates, when the second display control unit determines that the user selects one of the main points.

2. A navigation apparatus for displaying information required reaching a destination on a display screen to guide a vehicle to the destination, the navigation apparatus comprising:

a third display control unit for determining whether or not a user gives a command to display a real image on the display screen, and displaying a real image showing surrounding of a main point on a route to the destination on the display screen on the basis of real image data corresponding to the real image.

3. A navigation apparatus for displaying information required reaching a destination on a display screen to guide a vehicle to the destination, the navigation apparatus comprising:

a first selection unit for selecting a point, a real image of which is to be displayed on the display screen, from among main points on a route to the destination on the basis of movement state of the vehicle; and

a fourth display control unit for displaying a real image showing surrounding of the point selected by the second selection unit on the basis of real image data corresponding to the real image.

4. The navigation apparatus according to claim 3, wherein:

the movement state of the vehicle is position information of the vehicle, position information of the main points, and positional relation between a position of the vehicle and that of each main point.

5. The navigation apparatus according to claim 4, wherein the first selection unit selects a point at which the vehicle next arrives from among the main points as the point, a real image of which is to be displayed on the display screen, on the basis of the positional relation.

6. The navigation apparatus according to claim 4, wherein the first selection unit selects a point which is closest to the vehicle from among the main points as the point, a real image of which is to be displayed on the display screen, on the basis of the positional relation.
