Abstract
An embodiment of the invention provides a navigation system. A global positioning device outputs location information. A map database provides map information according to the location information. An active area recorder determines a viewing-area, and sketches a first active area according to the viewing-area and a first moving track of a positioning pattern corresponding to the location information. An image processing unit receives the map information and the first moving track and generates display data displayed on a display device.
