Abstract
In apparatus and method for navigating a mobile body such as a vehicle through a road map display image, an angle of a displayed traffic intersection with respect to, for example, a lateral axis crossing the traffic intersection is made coincident with an angle of an actually corresponding traffic intersection. That is to say, display coordinates at a predetermined part (for example, the traffic intersection) of a display image in a form of bird's eye view are modified, the predetermined part meaning a view focusing point or area, so that a scale in a longitudinal direction is made coincident with that in a lateral direction at the predetermined part.
