  • Map display method in navigation system and navigation apparatus
    Patent number: 6825855
    Abstract: A map display method in a navigation system has a bird's-eye view display function of displaying a map image in conjunction with a background image. The map display method in a navigation system has a step of displaying a horizon that indicates a boundary between the map image and the background image, and is rounded at least in part. Besides the bird's-eye view display effect, the method can enhance a sense of realism of the bird's-eye view display. Thus, it can solve a problem of a conventional method in that the bird's-eye view display effect cannot be achieved satisfactorily because the conventional method displays a pseudo horizon in a straight line to indicate the boundary between the map image region and the background image region.
