Abstract

A method for controlling display of an object displayed on a touch screen in a mobile terminal is provided. The method includes displaying the object on the touch screen, generating an extension bar in response to a touch that is detected on the touch screen for a period of time, generating a zoom window in response to resizing of the extension bar, and zooming in and displaying content of the object in response to movement of the generated zoom window.

Claims

1. A method for controlling display of an object displayed on a touch screen in an electronic terminal, the method comprising:

displaying the object including text on the touch screen of the electronic device;

displaying an extension bar for selecting the text and a zoom button for displaying a zoom window, in response to a first touch input that is detected on the touch screen of the electronic device for a period of time; and

if a second touch input is detected on the zoom button, displaying the zoom window for displaying enlarged text corresponding to the text on the zoom window.

2. The method of claim 1, wherein the zoom window includes at least one move button comprising a move-up button, a move-down button, a move-left button and a move-right button, and the text of the object is zoomed in and displayed in response to a touch input on the at least one move button.

3. The method of claim 1, wherein the extension bar is resized in at least one of up, down, left and right directions.

4. The method of claim 1, wherein the zoom window is used to zoom in and display the text of the object in a fixed position in response to movement by a touch input of an object displayed on the touch screen.

5. The method of claim 1, wherein the zoom window is moved along with movement by a touch input of an object displayed on the touch screen.

6. The method of claim 1, wherein, if a touch input is detected on the displayed object in a portion other than the zoom window for a period of time, the zoom window moves to a point of the detected touch input and displays zoomed-in the text of the object.

7. The method of claim 1, wherein, if a touch input is made in a portion other than the extension bar and the zoom window, the extension bar and the zoom window are released.

8. The method of claim 1, wherein the zoom is variable.

16. The method of claim 1, further comprising:

displaying a first screen and a second screen by splitting the touch screen in response to the touch input, and selection of a zoom window function; and

displaying enlarged contents corresponding to contents in a zoom window on the first screen, on the second screen.

17. The method of claim 16, wherein the second screen is used to zoom in and display the content corresponding to a zoom window in response to movement of the zoom window in at least one of up, down, left and right directions.

18. The method of claim 16, wherein the zoom window on the first screen is reduced in size in response to a pinch-to-zoom-in input on the second screen.

19. The method of claim 16, wherein the zoom window on the first screen is enlarged in size in response to a pinch-to-zoom-out input on the second screen.

20. The method of claim 16, wherein the second screen is used to zoom in and display content in the zoom window.

21. The method of claim 16, wherein content corresponding to a moving direction of a drag by a touch input on the second screen is displayed in the zoom window.

22. The method of claim 16, further comprising converting the first screen into a keypad if a text window is selected on at least one of the first screen and the second screen.

9. An electronic device for controlling display of an object displayed on a touch screen, the electronic device comprising:

the touch screen configured to display the object including text; and

at least one processor configured to;

display, on the touch screen, an extension bar for selecting the text and a zoom button for displaying a zoom window, in response to a first touch input that is detected on the touch screen for a period of time, and

if a second touch input is detected on the zoom button, display, on the touch screen, the zoom window for displaying enlarged text corresponding to the text on the zoom window.

10. The electronic device of claim 9,

wherein the generated zoom window includes at least one move button of a move-up button, a move-down button, a move-left button and a move-right button, and

wherein the at least one processor is further configured to zoom in and display the text of the object in response to a touch on the at least one move button.

11. The electronic device of claim 9, wherein the extension bar is resized in at least one of up, down, left and right directions.

12. The electronic device of claim 9, wherein the at least one processor is further configured to:

zoom in on the text of the object in a fixed position, and

display the zoomed-in the text of the object in the zoom window in response to movement by a touch input of an object displayed on the touch screen.

13. The electronic device of claim 9, wherein the at least one processor is further configured to control movement of the zoom window along with movement by a touch input of an object displayed on the touch screen.

14. The electronic device of claim 9, wherein, if a touch input is detected on the displayed object in a portion other than the zoom window for a period of time, the at least one processor is further configured to:

move the zoom window to a point of the detected touch input, and

zoom in and display the text of the object in response to the movement of the zoom window.

15. The electronic device of claim 9, wherein the at least one processor is further configured to release the extension bar and the zoom window in response to a touch input that is made in a portion other than the extension bar and the zoom window.

23. The electronic device of claim 9, wherein the at least one processor is further configured to:

display a first screen and second screen by splitting the touch screen in response to the touch input,

select a zoom window function, and

display enlarged contents corresponding to contents in a zoom window on a first screen, on a second screen.

24. The electronic device of claim 23, wherein the at least one processor is further configured to zoom in and display content on the second screen in response to movement of the zoom window in at least one of up, down, left and right directions.

25. The electronic device of claim 23, wherein the at least one processor is further configured to reduce a size of the zoom window on the first screen upon detecting a pinch-to-zoom-in input on the second screen.

26. The electronic device of claim 23, wherein the at least one processor is further configured to enlarge a size of the zoom window on the first screen upon detecting a pinch-to-zoom-out input on the second screen.

27. The electronic device of claim 23, wherein the second screen is used to zoom in and display content in the zoom window.

28. The electronic device of claim 23, wherein the at least one processor is further configured to display, in the zoom window, content corresponding to a moving direction of a drag by a touch input on the second screen.

29. The electronic device of claim 23, wherein the at least one processor is further configured to convert at least one of the first screen and the second screen into a keypad, if a text window is selected on at least one of the first screen and the second screen.

30. The electronic device of claim 23, wherein the touch screen is split into the first screen and the second screen if the zoom window function is selected.

31. The electronic device of claim 23, wherein each of the first screen and the second screen is variably resized.

32. The electronic device of claim 29,

wherein the first screen detects one of a pinch-to-zoom-in and a pinch-to-zoom-out and alters magnification of the content of the first screen in correspondence to a movement of the one of the pinch-to-zoom-in and the pinch-to-zoom-out, and

wherein a size of the second screen changes in inverse proportion to the magnification of the content of the first screen.
