Abstract
A display method and apparatus for a navigation system utilizes enables a smooth map scroll operation when a scroll direction is changed sharply. Such a smooth map scroll operation is applied to a situation where such a change of scroll direction is within a predetermined angle range by adding a scroll direction bias for each movement. The display method dynamically adjusts the scroll direction bias and the update frequency depending on the degree of direction change and the available system resources such as a processing speed in the navigation system. Therefore, the navigation system is able to display the smooth operation of the map scroll so that the user is able to recognize the images actually illustrated on the screen and to reach the intended location of the map image quickly and accurately.
