Abstract

A method for displaying a display screen on a portable terminal is provided. The method includes displaying an interface including a zoom-in area and a zoom-out area when a first touch input and a second touch input are detected; performing a zoom-in display of the display screen when the second touch input moves to the zoom-in area; and performing a zoom-out display of the display screen when the second touch input moves to the zoom-out area.

Claims

1. A method for displaying a display screen on a portable terminal, the method comprising:

displaying an interface including a zoom-in area and a zoom-out area when a first touch input and a second touch input are detected;

performing a zoom-in display of the display screen when the second touch input moves to the zoom-in area; and

performing a zoom-out display of the display screen when the second touch input moves to the zoom-out area.

2. The method according to claim 1, wherein the displaying of the interface comprises:

displaying the interface including the zoom-in area, a neutral area, and the zoom-out area when the first touch input and the second touch input are detected,

wherein the neutral area is an area that divides the zoom-in area and the zoom-out area.

3. The method according to claim 2, wherein the zoom-in area, the neutral area, and the zoom-out area are displayed in forms of concentric circles with a point where the first touch input is detected as a center of the concentric circles.

4. The method according to claim 2, wherein the neutral area is displayed at a point where the second touch input is detect, and

the display screen is not zoomed in or zoomed out when a touch of a user is input in the neutral area.

5. The method according to claim 1, wherein the performing of the zoom-in display comprises:

detecting a time when the second touch input is performed in the zoom-in area when the second touch input moves to the zoom-in area; and

performing the zoom-in display of the display screen corresponding to the detected time.

6. The method according to claim 5, wherein the performing of the zoom-in display comprises:

checking a distance between the first touch input and the second touch input moving to the zoom-in area, when the second touch input moves to the zoom-in area, and

performing the zoom-in display of the display screen at a speed corresponding to the checked distance.

7. The method according to claim 6, wherein the performing of the zoom-in display comprises performing the zoom-in display of the display screen at a speed increasing in proportion to the checked distance.

8. The method according to claim 1, wherein the performing of the zoom-out display comprises:

detecting a time when the second touch input is performed in the zoom-out area when the second touch input moves to the zoom-out area; and

performing the zoom-out display of the display screen corresponding to the detected time.

9. The method according to claim 8, wherein the performing of the zoom-in display comprises:

checking a distance between the first touch input and the second touch input moving to the zoom-out area, when the second touch input moves to the zoom-out area, and

performing the zoom-out display of the display screen at a speed corresponding to the checked distance.

10. The method according to claim 9, wherein the performing of the zoom-out display comprises performing the zoom-out display of the display screen at a speed in reverse proportion to a distance between the moved second touch input and the first touch input.

11. The method according to claim 1, wherein an overlay display of the interface is performed on the display screen in a predetermined transparency.

12. An apparatus for displaying a display screen on a portable terminal, the apparatus comprising:

a display unit that includes a touch screen; and

a controller configured to display an interface including a zoom-in area and a zoom-out area when a first touch input and a second touch input are detected, perform a zoom-in display of the display screen when the second touch input moves to the zoom-in area, and perform a zoom-out display of the display screen when the second touch input moves to the zoom-out area.

13. The apparatus according to claim 12, wherein the controller is further configured to display the interface including the zoom-in area, a neutral area, and the zoom-out area when the first touch input and the second touch input are detected,

wherein the neutral area is an area that divides the zoom-in area and the zoom-out area.

14. The apparatus according to claim 13, wherein the zoom-in area, the neutral area, and the zoom-out area are displayed in forms of concentric circles with a point where the first touch input is detected as a center of the concentric circles.

15. The apparatus according to claim 13, wherein the controller is configured to display the neutral area at a point where the second touch input is detected, and the display screen is not zoomed in or zoomed out when a touch of a user is input in the neutral area.

16. The apparatus according to claim 12, wherein the controller is further configured to detect a time when the second touch input is performed in the zoom-in area when the second touch input moves to the zoom-in area, and to perform the zoom-in display of the display screen corresponding to the detected time.

17. The apparatus according to claim 16, wherein the controller is further configured to check a distance between the first touch input and the second touch input moving to the zoom-in area, when the second touch input moves to the zoom-in area, and to perform the zoom-in display of the display screen at a speed corresponding to the checked distance.

18. The apparatus according to claim 17, wherein the controller is further configured to perform the zoom-in display of the display screen at a speed increasing in proportion to the checked distance.

19. The apparatus according to claim 12, wherein the controller is further configured to detect a time when the second touch input is performed in the zoom-out area when the second touch input moves to the zoom-out area, and to perform the zoom-out display of the display screen corresponding to the detected time.

20. The apparatus according to claim 17, wherein the controller is further configured to check a distance between the first touch input and the second touch input moving to the zoom-out area, when the second touch input moves to the zoom-out area, and to perform the zoom-out display of the display screen at a speed corresponding to the checked distance.

21. The apparatus according to claim 20, wherein the controller is further configured to perform the zoom-out display of the display screen at a speed in reverse proportion to a distance between the moved second touch input and the first touch input.

22. The apparatus according to claim 12, wherein the controller is further configured to performs an overlay display of the interface on the display screen in a predetermined transparency.
