Navigation apparatus with shape change display function
First Claim
1. A navigation apparatus comprising:
- a recording medium having recorded therein at least map data including road data, and shape data characterizing at least an object which is included in said map data and serves as a main object for recognizing a feature of a map;
an image forming unit for forming image information for generating a perspective image obtained when a map segment is seen from a desired viewing point, based on said map data and said shape data;
a display unit for displaying the image information formed by said image forming unit; and
a control unit for controlling said recording medium, said image forming unit, and said display unit; and
a shape data changing unit;
wherein said control unit controls said shape data changing unit to change at least a part of said shape data based on at least said map data, and also controls said image forming unit to form the perspective image based on said map data, said shape data, and shape data changed by said shape data changing unit.

Abstract
A navigation apparatus which can preferentially recognize important information on a map hidden by buildings, mountains, etc. Which were stereoscopically displayed and enables a set route or a present position of a vehicle to be easily recognized. A navigation apparatus has: a recording medium on which at least map data having a road and shape data which is included in the map data and serves as a main landmark object to recognize a feature of a map have been recorded; an image forming unit for forming image information when the map data is seen from a desired sight point position on the basis of the map data and the shape data; a display unit for displaying on the basis of the image information formed by the image forming unit; and a control unit for controlling the recording medium, image forming unit, and display unit. The control unit controls a shape data changing unit to change at least a part of the shape data on the basis of at least the map data and also controls the image forming unit to form the image information on the basis of the map data, the shape data, and shape data changed by the shape data changing unit.

7. A method of displaying navigation data for a vehicle, comprising:
-
providing a memory having stored therein map data including road information, and shape data for at least an object situated within the area represented by said map data; determining a location of said vehicle; forming image information for displaying perspective image corresponding to a view from a desired viewing point based on said map data, said shape data and location of said vehicle; detecting areas of overlap of said shape data and said road information in said image information; selectively modifying said shape data in said areas of overlap; and displaying said perspective image based on said map data said shape data and selectively modified shape data. - View Dependent Claims (8)
