Abstract
A navigation apparatus includes a map data storage apparatus which obtains map data needed for drawing an object; a map buffer; a map drawing unit which generates image information corresponding to an object included in a background image on the basis of the map data, and stores the image information in a frame buffer; and a display processing unit which reads out the image information stored in the frame buffer and displays a map image on a display apparatus. The map drawing unit generates shadow image information for a shadow region of the object which is a region sandwiched between an outline of the object and an outline of the object after the object has been moved in a predetermined direction.
