Abstract

A method, medium and apparatus browsing images is disclosed. The method browsing images includes sensing acceleration imparted to a portable digital device, and moving an image onto a display area in accordance with a tilt angle of the portable digital device if the sensed acceleration is greater than a first threshold value.

Claims

1. A method of browsing images, comprising:

sensing acceleration imparted to a portable digital device; and

moving an image onto a display area in accordance with a tilt angle of the portable digital device if the sensed acceleration is greater than a first threshold value.

2. The method of claim 1, wherein the moving of the image comprises increasing a moving distance of the image, as the tilt angle increases while remaining below a second threshold value.

3. The method of claim 1, wherein the moving of the image comprises increasing movement velocity of the image as the tilt angle increases while remaining below a second threshold value.

4. The method of claim 1, wherein the moving of the image comprises increasing movement velocity of the image as a duration of a tilt time increases, while the tilt angle remains below a second threshold value.

5. The method of claim 1, wherein the moving of the image comprises increasing a movement velocity of the image as a change rate of the tilt angle increases while the tilt angle remains below a second threshold value.

6. The method of claim 1, wherein the moving of the image comprises moving the image to a center of the display area if there is no change in the tilt angle.

7. The method of claim 6, wherein the moving of the image comprises gradually moving a midpoint of the image towards a midpoint of the display area in accordance with a time period commenced immediately after a moment when the tilt angle is no longer changing.

8. The method of claim 6, wherein the moving of the image comprises controlling the image to move a midpoint of the image towards a midpoint of the display area, while making the midpoint of the image oscillate around the midpoint of the display area.

9. The method of claim 1, wherein the moving of the image comprises moving an adjacent image to a center of the display area if the tilt angle is greater than a second threshold value.

10. The method of claim 9, wherein the moving of the image comprises gradually moving a midpoint of the adjacent image to a midpoint of the display area in accordance with a time period commencing the moment the tilt angle exceeds the second threshold value.

11. The method of claim 9, wherein the moving of the image comprises controlling the image to move a midpoint of the image towards a midpoint of the display area, while making the midpoint of the image oscillate in a predetermined direction around the midpoint of the display area.

12. The method of claim 1, wherein the moving of the image comprises moving the image onto the display area in accordance with the tilt angle of the portable digital device around a predetermined reference axis.

13. An apparatus browsing images, comprising:

a sensor unit to sense acceleration imparted to a portable digital device; and

a screen management unit to move an image onto a display area in accordance with a tilt angle of the portable digital device if the sensed acceleration is greater than a first threshold value.

14. The apparatus of claim 13, wherein the screen management unit increases a moving distance of the image, as the tilt angle increases while remaining below a second threshold value.

15. The apparatus of claim 13, wherein the moving of the image comprises increasing a movement velocity of the image as the tilt angle becomes increasing while less than a second threshold value.

16. The apparatus of claim 13, wherein the screen management unit increases movement velocity of the image, as a duration of a tilt time increases while the tilt angle remains below a second threshold value.

17. The apparatus of claim 13, wherein the screen management unit increases a movement velocity of the image as a change rate of the tilt angle increases while the tilt angle remains below a second threshold value.

18. The apparatus of claim 13, wherein the screen management unit moves the image to a center of the display area if there is no change in the tilt angle.

19. The apparatus of claim 18, wherein the screen management unit gradually moves a midpoint of the image towards a midpoint of the display area in accordance with a time period commenced immediately after a moment when the tilt angle is no longer changing.

20. The apparatus of claim 18, wherein the screen management unit controls the image to move a midpoint of the image towards a midpoint of the display area, while moving the midpoint of the image in a predetermined direction around the midpoint of the display area.

21. The apparatus of claim 13, wherein the screen management unit moves an adjacent image to a midpoint of the display area if the tilt angle is greater than a second threshold value.

22. The apparatus of claim 21, wherein the screen management unit gradually a midpoint of the adjacent image to the midpoint of the display area in accordance with a time period commencing the moment the tilt angle exceeds the second threshold value.

23. The apparatus of claim 21, wherein the screen management unit controls the image to move a midpoint of the image towards the midpoint of the display area, while moving the midpoint of the image in a predetermined direction around the midpoint of the display area.

24. The apparatus of claim 13, further comprising a measurement unit to measure the tilt angle around a predetermined reference axis.

25. An image browsing method, comprising:

measuring a tilt angle of a portable device; and

moving an image onto a display of the portable device, according to the measured tilt angle.

26. The method of claim 25, wherein the image is moved to replace an adjacent image currently displayed on the display.

27. The method of claim 25, wherein the moving of the image comprises increasing a moving distance of the image, as the tilt angle increases while remaining below a threshold value.

28. The method of claim 25, wherein the moving of the image comprises increasing movement velocity of the image as the tilt angle increases while remaining below a threshold value.

29. The method of claim 25, wherein the moving of the image comprises increasing a movement velocity of the image as a change rate of the tilt angle increases while the tilt angle remains below a threshold value.

30. The method of claim 25, wherein the moving of the image comprises moving the image to a center of the display area if there is no change in the tilt angle.

31. The method of claim 25, wherein the moving of the image comprises moving an adjacent image to a center of the display area if the tilt angle is greater than a threshold value.

32. The method of claim 31, wherein the moving of the image comprises gradually moving a midpoint of the adjacent image to a midpoint of the display area in accordance with a time period commencing the moment the tilt angle exceeds the threshold value.

33. At least one medium comprising computer readable code to control at least one processing element to implement the method of claim 25.
