NAVIGATION SYSTEM AND NAVIGATION TERMINAL

PROBLEM TO BE SOLVED: To provide a navigation system that easily permits screen switching and participation from a simple terminal, and can be achieved in a compact size and inexpensively. SOLUTION: A real image rendering means 12 captures a real image from a camera 11 to render the real image. A perspective projection rendering means 16 renders a perspective projection on which the shape of a building on the periphery of the current location of own terminal, acquired by searching a building three-dimensional database 15 based on the positional information on the own terminal from a position measurement means 14, and a landscape overlooked in the range of a view angle sought by focal distance information from the camera 11. A content rendering means 18 renders information on content acquired by searching a content database 17 based on link information from the perspective projection rendering means 16. A two-dimensional map rendering means 19 renders information on neighboring content by superimposing on a two-dimensional map. A screen combining means 13 combines rendering data from each of the above means to send to a display part.
