Abstract

An apparatus and method controls a screen change in a portable terminal to modify a status (e.g., a screen shift to a specific region or a screen rotation) of a screen being displayed by using a simple touch input. The apparatus includes a screen change unit for displaying a center point for a screen rotation if a touch input is released.

Claims

1. An apparatus for changing a screen status in a portable terminal, the apparatus comprising a screen change unit configured to display a center point for a screen rotation when a touch input is released.

2. The apparatus of claim 1, further comprising:

a controller configured to detect the touch input, wherein the touch input is a touch interaction that is associated with changing the screen status.

3. The apparatus of claim 1, wherein the screen change unit rotates a screen being displayed about the displayed center point.

4. The apparatus of claim 3, wherein the screen change unit rotates the screen being displayed along an X-axis or a Y-axis about the displayed center point.

5. The apparatus of claim 3, wherein the screen change unit rotates the screen being displayed about the displayed center point in response to a touch interaction that touches the displayed center point.

6. The apparatus of claim 1, wherein the screen change unit displays the center point where the touch input is released.

7. The apparatus of claim 1, wherein the screen change releases the displayed center point for the screen rotation if the touch interaction that touches the displayed center point is not detected for a specific time period.

8. The apparatus of claim 1, wherein if the touch input is associated with a screen shift for shifting the displayed screen, the screen change unit displays the center point for the screen rotation where the touch input associated with the screen shift is released.

9. The apparatus of claim 1, wherein the center point for the screen rotation is a point for indicating a center of rotation the displayed screen.

10. The apparatus of claim 1, wherein the screen change unit releases the displayed center point when a touch interaction associated with ending the screen status change is detected.

12. The method of claim 1, further comprising:

detecting the touch input, wherein the touch input is a touch interaction that is associated with changing the screen status.

20. The method of claim 1, further comprising releasing the displayed center point when a touch interaction associated with ending the screen status change is detected.

11. A method for changing a screen status in a portable terminal, the method comprising displaying a center point for a screen rotation when a touch input is released.

13. The method of claim 11, further comprising, rotating a screen being displayed about the displayed center point.

14. The method of claim 13, wherein rotating the screen being displayed comprises rotating the screen being displayed along an X-axis or a Y-axis about the displayed center point.

15. The method of claim 13, further comprising rotating the screen being displayed about the displayed center point in response to a touch interaction that touches the displayed center point.

16. The method of claim 11, further comprising displaying the center point where the touch input is released.

17. The method of claim 11, further comprising releasing the displayed center point for the screen rotation if the touch interaction that touches the displayed center point is not detected for a specific time period.

18. The method of claim 11, wherein if the touch input is associated with a screen shift for shifting the displayed screen, the center point for the screen rotation is displayed where the touch input associated with the screen shift is released.

19. The method of claim 11, wherein the center point for the screen rotation is a point for indicating a center of rotation of the displayed screen.
