ABSTRACT:
A method and apparatus for a navigation system achieves a smooth and, intuitive scrolling operation by checking available resources such as a computational power of the navigation system and map data stored in a video memory to determine an optimum scrolling operation and to dynamically adjust a scroll speed and a scale factor to move an image on a monitor screen to a specified location. The method includes the steps of: receiving a scroll signal from an input device for scrolling an image on the monitor screen, checking a current condition of the navigation system related to the scroll operation, and conducting the scroll operation while adjusting the scroll speed and scale factor of the image based on the current condition.
