ABSTRACT:
A map searching unit reads from a map storing unit map data adjacent to the current position of a vehicle calculated by a position calculator or map data having a range of a map to be displayed specified by an input unit. A processing unit performs a perspective transformation of eye point and focus point coordinates inputted from the input unit, maps the map data on the transformed coordinates, performs clipping, and then makes an output unit display the map after mapping.
