ABSTRACT:
A navigation apparatus arranged in such a manner that the background image and a marker image denoting the user's vehicle position are moved in the opposite directions to each other when the vehicle speed is raised. As a result of the relative movement, the coincidence between the marker and the map image is realized. Since the background image and the marker image are moved in the opposite directions to each other, the scroll speed of the background image can be moderated.
