Navigation apparatus
First Claim
1. A navigation apparatus, comprising:
- a display screen;
a first display control unit which makes the display screen display a real image, based on real image data formed to be able to associate with positional coordinates and which determines a limited display area including a current position of the navigational apparatus that is less than the real image based on the current position of the navigation apparatus; and
a second display control unit which displays additional information over the real image displayed on the display screen, based on additional information data corresponding to character information and position data indicating a position where the additional information should be displayed,wherein the second display control unit displays the additional information within an area on the real image displayed on the display screen other than the limited display area.

Abstract
The navigation apparatus includes a unit for displaying a real image on a display screen on the basis of real image data, and a unit for displaying additional information such as a primary place name or a primary building name in a position where the additional information should be displayed on the real image, on the basis of additional information data corresponding to the additional information and position data showing the position where the additional information should be displayed. Further, the navigation apparatus has a function of limiting the display area of the additional information so as to prevent the additional information from being displayed in an area having a relatively high level of importance. Thus, the real image is prevented from being difficult to see in the area having a high level of importance.

12. A navigation apparatus, comprising:
-
a display screen which displays information required for reaching a destination to guide the navigation apparatus to the destination; and a display control unit which displays on the display screen real images showing peripheries of points on a guide route subsequently at predetermined time intervals, from a second point to a first point along the guide route on the basis of route information and real image data, wherein; the route information relates to the guide route for the navigation apparatus to reach a first point; the real image data is formed to associate with positional coordinates; and the navigation apparatus will pass through the second point before reaching the first point.
