Abstract

A navigation apparatus displays a map so as to support a travel of a movable body. A map information displaying apparatus in the navigation apparatus is provided with: a character data extracting device for extracting character data corresponding to characters from map data corresponding to the map; a map data converting device for converting the map data, which does not include the character data, to a bird's-eye view which is a one-point perspective projection view in which a topography corresponding to the map data is seen from one point in a sky, and outputting bird's-eye view map data indicating the bird's-eye view of the converted map data; a character data converting device for converting the extracted character data to the bird's-eye view, and outputting bird's-eye view character data indicating the bird's-eye view of the converted character data; a synthesizing device for synthesizing the outputted bird's-eye view character data and the outputted bird's-eye view map data corresponding to the bird's-eye view character data with each other, and generating the synthesized bird's-eye view character and map data; and a displaying device for displaying a synthesized bird's-eye view corresponding to the synthesized bird's-eye view character and map data generated by the synthesizing device.
