Abstract

Provided are an apparatus and method for changing a position of an image on a screen of an image display device, such as a map provided by a navigation system or mobile phone and a broadcast program played back by a television receiver, allowing the image to be reduced, enlarged, rotated, etc. through touching the on-screen image, and to a navigation system using the apparatus and method. The apparatus includes a display, a touch sensor, and a controller. The display displays an image. The touch sensor senses touching of the image displayed on the display. The controller changes a position of the image displayed on the display in a touched direction sensed by the touch sensor. The touch sensor generates positional coordinates of a touched point of the image sensed by the touch sensor, and relays the generated positional coordinates to the controller.

Claims

1. An apparatus for changing an on-screen image position, the apparatus comprising:

a display for displaying an image;

a touch sensor for sensing touching of the image displayed on the display; and

a controller for changing a position of the image displayed on the display in a touched direction sensed by the touch sensor,

wherein the touch sensor generates positional coordinates of a touched point of the image sensed by the touch sensor, and relays the generated positional coordinates to the controller.

2. The apparatus of claim 1, wherein when the touched point of the image is the only point touched, the controller displays a scroll at the touched point.

3. The apparatus of claim 1, wherein when at least two points are touched and the touched points are moved in a rotating direction, the controller rotates the displayed image in the rotating direction.

4. The apparatus of claim 1, wherein when at least two points are touched and the touched points are moved in a reducing direction, the controller reduces the displayed image in the reducing direction.

5. The apparatus of claim 1, wherein when at least two points are touched and the touched points are moved in an enlarging direction, the controller enlarges the displayed image in the enlarging direction.

6. A method of changing a position of an image on-screen, comprising:

displaying an image;

sensing a touching of the displayed image, and generating positional coordinates of a touched point; and

changing a position of the displayed image in a sensed touched direction.

7. The method of claim 6, wherein the changing of the position of the displayed image in the sensed touched direction comprises, when the touched point is the only point touched, displaying a scroll at the touched point.

8. The method of claim 6, wherein the changing of the position of the displayed image in the sensed touched direction comprises, when at least two points are touched and the touched points are moved in a rotating direction, rotating the displayed image in the rotating direction.

9. The method of claim 6, wherein the changing of the position of the displayed image in the sensed touched direction comprises, when at least two points are touched and the touched points are moved in a reducing direction, reducing the displayed image in the reducing direction.

10. The method of claim 6, wherein the changing of the position of the displayed image in the sensed touched direction comprises, when at least two points are touched and the touched points are moved in an enlarging direction, enlarging the displayed image in the enlarging direction.

11. A navigation system comprising:

a navigation receiver for receiving positional data from a satellite, and determining a current position of a vehicle from the received positional data;

a display for displaying a map showing a direction of travel of the vehicle;

a touch sensor for sensing touching of the map displayed on the display;

a storage for storing map data; and

a controller for displaying the position of the vehicle determined by the navigation receiver on the map stored in the storage, and changing a position of the map displayed on the display in a touched direction sensed by the touch sensor,

wherein the touch sensor generates positional coordinates of a touched point of the map sensed by the touch sensor, and relays the generated positional coordinates to the controller.

12. The navigation system of claim 11, wherein when the touched point is the only point touched, the controller displays a scroll at the touched point.

13. The navigation system of claim 11, wherein when at least two points are touched and the touched points are moved in a rotating direction, the controller rotates the displayed map in the rotating direction.

14. The navigation system of claim 11, wherein when at least two points are touched, and the touched points are moved in a reducing direction, the controller reduces the displayed map in the reducing direction.

15. The navigation system of claim 11, wherein when at least two points are touched, and the touched points are moved in an enlarging direction, the controller enlarges the displayed map in the enlarging direction.

16. A method of changing a position of a map in a navigation system, comprising:

receiving positional data from a satellite, and determining a current position of a vehicle from the received positional data;

displaying a predetermined map showing the position of the vehicle thereon;

sensing touching of the displayed map, and generating positional coordinates of a touched point; and

changing a position of the displayed map in a sensed touched direction.

17. The method of claim 16, wherein the changing of the position of the displayed map in the sensed touched direction comprises displaying a scroll at the touched point when the touched point is the only point touched.

18. The method of claim 16, wherein the changing of the position of the displayed map in the sensed touched direction comprises, when at least two points are touched and the touched points are moved in a rotating direction, rotating the displayed map in the rotating direction.

19. The method of claim 16, wherein the changing of the position of the displayed map in the sensed touched direction comprises, when at least two points are touched and the touched points are moved in a reducing direction, reducing the displayed map in the reducing direction.

20. The method of claim 16, wherein the changing of the position of the displayed map in the sensed touched direction comprises, when at least two points are touched and the touched points are moved in an enlarging direction, enlarging the displayed map in the enlarging direction.
