Abstract

An apparatus and method zoom into a screen in an electronic device employing a touch screen. The method includes, upon detection of a touch input, confirming a zoom-in area by considering touch information, confirming a zoom-in ratio for the zoom-in area, and displaying the zoom-in area by zooming in the area according to the zoom-in ratio.

Claims

1. A method of zooming in a screen in an electronic device employing a touch screen, the method comprising:

in response to detecting a touch input, determining, a zoom-in area based on touch information;

determining a zoom-in ratio for the zoom-in area; and

displaying the zoom-in area by zooming into the zoom-in area according to the zoom-in ratio.

2. The method of claim 1, wherein determining the zoom-in area comprises, in response to detecting a multi-touch input, determining the zoom-in area based on multiple touch points associated with the multi-touch input.

3. The method of claim 1, wherein determining the zoom-in area comprises:

in response to detecting a first touch input, activating a screen zoom-in mode based on a touch duration time of the first touch input; and

in response to detecting a second touch input, determining the zoom-in area based on multiple touch points associated with the first touch input and the second touch input.

4. The method of claim 1, wherein determining the zoom-in area comprises:

in response to detecting a first touch input, activating a screen zoom-in mode based on a touch duration time of the first touch input; and

in response to detecting of a drag of the first touch input, determining the screen zoom-in area based on a drag distance of the first touch input.

5. The method of claim 1, wherein determining the zoom-in area comprises:

in response to detecting a touch input for a zoom-in icon, activating a screen zoom-in mode; and

in response to detecting at least two touch inputs, determining the zoom-in area based on multiple touch points associated with the touch inputs.

6. The method of claim 1, wherein determining the zoom-in ratio comprises:

determining a size of the zoom-in area;

determining a total size of a display area; and

determining the zoom-in ratio based on the size of the zoom-in area and the total size of the display area.

7. The method of claim 1, wherein determining the zoom-in ratio comprises confirming a zoom-in ratio determined by a user.

8. An apparatus for zooming in a screen in an electronic device, the apparatus comprising:

a touch screen; and

a controller configured to, in response to detecting a touch input through the touch screen, generate a display of a zoom-in area, determined based on touch information, by zooming into the zoom-in area according to a zoom-in ratio.

9. The apparatus of claim 8, wherein in response to detecting a multi-touch input through the touch screen, the controller is configured to determine the zoom-in area based on multiple touch points associated with the multi-touch input.

10. The apparatus of claim 8, wherein in response to detecting a first touch input, the controller is configured to activate a screen zoom-in mode through the touch screen based on a touch duration time of the first touch input, and in response to detecting a second touch input, determine the zoom-in area based on multiple touch points associated with the first touch input and the second touch input.

11. The apparatus of claim 8, wherein in response to detecting a first touch input, the controller is configured to activate a screen zoom-in mode through the touch screen based on a touch duration time of the first touch input, and in response to detecting a drag of the first touch input, determines the screen zoom-in area based on a drag distance of the first touch input.

12. The apparatus of claim 8, wherein in response to detecting a touch input for a zoom-in icon through the screen touch, the controller is configured to activate a screen zoom-in mode, and in response to detecting at least two touch inputs through the touch screen, determine the zoom-in area based on multiple touch points associated with the touch inputs.

13. The apparatus of claim 8, wherein the controller is configured to determine the zoom-in ratio by comparing the size of the zoom-in area and the total size of the display area.

14. The apparatus of claim 8, wherein the controller is configured to determine a zoom-in ratio determined by a user.

15. A non-transitory computer-readable medium embodying a program, the program comprising program code for:

in response to detecting a touch input on a touch screen, determining a zoom-in area based on touch information

determining a zoom-in ratio for the zoom-in area; and

displaying the zoom-in area by zooming into the zoom-in area according to the zoom-in ratio.

16. The computer-readable medium of claim 15, further comprising program code for, in response to detecting a multi-touch input through the touch screen, determining the zoom-in area based on multiple touch points associated with the multi-touch input.

17. The computer-readable medium of claim 15, further comprising program code for, in response to detecting a first touch input through the touch screen, activating a screen zoom-in mode based on a touch duration time of the first touch input, and in response to detecting a second touch input, determining the zoom-in area based on multiple touch points associated with the first touch input and the second touch input.

18. The computer-readable medium of claim 15, further comprising a program code for, in response to detecting a first touch input through the touch screen, activating a screen zoom-in mode based on a touch duration time of the first touch input, and in response to detecting a drag of the first touch input, determining the screen zoom-in area based on a drag distance of the first touch input.

19. The computer-readable medium of claim 15, further comprising program code for, in response to detecting a touch input for a zoom-in icon through the touch screen, activating a screen zoom-in mode, and in response to detecting at least two touch inputs through the touch screen, determining the zoom-in area based on multiple touch points based on the touch inputs.

20. The computer-readable medium of claim 15, further comprising program code for determining the zoom-in ratio by comparing the size of the zoom-in area and the total size of the display area.

21. The computer-readable medium of claim 15, further comprising program code for confirming a zoom-in ratio determined by a user.
