First Claim
Patent Images
1. A map displaying method to display a map on a screen, the method comprising:
- establishing a first area on the map that is not compressed based on a current location of an object on the map;
non-linearly compressing a second area adjacent to the first area at different compression ratios according to a distance from the first area to generate a third area; and
displaying the first area and the third area on the screen such that a distance between an edge of the screen and a boundary of the third area and the first area in a moving direction of the object is greater than a distance between another boundary of the third area and the first area and another edge of the screen away from the moving direction.

16. A map displaying apparatus to display a map on a screen, the apparatus comprising:
-
a non-compression area establishing unit to establish a first area on the map that is not compressed based on a current location of an object on the map and; a compression area generating unit to non-linearly compress a second area adjacent to the first area at different compression ratios according to a distance from the first area to generate a third area; and a display unit to display the first area and the third area on the screen such that a distance between an edge of the screen and a boundary of the third area and the first area in a moving direction of the object is greater than a distance between another boundary of the third area and the first area and another edge of the screen away from the moving direction. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

33. A map displaying method to display a map including a current location within a first or second area of the map on a screen of a navigation terminal, the method comprising:
-
non-linearly compressing the second area at different compression ratios according to a distance from the first area to generate a third area without compressing the first area; and displaying the first area and the third area on the screen such that a distance between an edge of the screen and a boundary of the third area and the first area in a moving direction is greater than a distance between another boundary of the third area and the first area and another edge of the screen away from the moving direction. - View Dependent Claims (34, 35, 36)
