Abstract
A navigation method and system for displaying a map image and shrinking the map image relative to a center point or a reference line on the map image by a non-linear function so that an image outside of the display screen becomes visible on the screen without much decreasing the size thereof. In the first embodiment, the image is coaxially shrinked relative to the center point. In the second embodiment, the images perpendicular to the reference line are shifted toward the reference line. Because of the non-linear function, the images are shrinked with higher degree at around the center point or the reference line than that far away, thereby bringing in the far away images without much decreasing the size thereof. The shrink ratios of the images at the same distance from the center point or the reference line are the same throughout the display screen.
