Abstract

A wireless communication terminal is provided. The wireless communication terminal includes a display that includes a touch screen configured to recognize touch inputs; a memory configured to store image data; and a controller configured to communicate with the memory, the display, and the touch screen. The controller is further configured to display at least a portion of the image having a first scale in the display, wherein the controller defines a reference line associated with the displayed portion of the image and recognizes a first touch input to define a manipulation region associated with the reference line where a portion of the image in the manipulation region is gradually removed or reinstated in response to a movement of the first touch input relative to the reference line, while maintaining the same first scale of the image that is displayed outside of the manipulation region.

Claims

1. A wireless communication terminal comprising:

a display comprising a touch screen configured to recognize touch inputs;

a memory configured to store image data; and

a controller configured to communicate with the memory, the display and the touch screen, the controller further configured to display at least a portion of the image having a first scale in the display, wherein the controller defines a reference line associated with the displayed portion of the image and recognizes a first touch input to define a manipulation region associated with the reference line where a portion of the image in the manipulation region is gradually removed or reinstated in response to a movement of the first touch input relative to the reference line while maintaining the same first scale of the image that is displayed outside of the manipulation region.

2. The wireless communication terminal of claim 1, wherein the controller is further configured to display a contiguous portion of the image having the first scale while the image in the manipulation region is being removed.

3. The wireless communication terminal of claim 1, wherein the controller is further configured to recognize a second touch input to alter the image in the manipulation region in response to the movement of both the first and second touch inputs relative to the reference line.

4. The wireless communication terminal of claim 1, wherein the manipulation region is determined by a user defined boundary.

5. The wireless communication terminal of claim 4, wherein the user defined boundary comprises a rectangle.

6. The wireless communication terminal of claim 1, wherein the manipulation region is not maintained depending on a first command provided by a user or a second command stored in the memory.

7. The wireless communication terminal of claim 1, wherein the image data comprises an image of a map.

8. The wireless communication terminal of claim 1, wherein each of the touch inputs comprises either a proximity touch or a contact touch on the touch screen by a pointer.

9. The wireless communication terminal of claim 8, wherein the pointer is a stylus or a finger of a user.

10. A wireless communication terminal comprising:

a display comprising a touch screen configured to recognize touch inputs;

a memory configured to store image data; and

a controller configured to communicate with the memory, the display and the touch screen, the controller further configured to display at least a portion of the image having a first scale in the display, wherein the controller defines a reference line associated with the displayed portion of the image and recognizing a first touch input to define a manipulation region associated with the reference line where a portion of the image in the manipulation region is gradually compressed or expanded in response to a movement of the first touch input relative to the reference line while maintaining the same first scale of the image that is displayed outside of the manipulation region.

11. The wireless communication terminal of claim 10, wherein the image in the manipulation region is removed in response to the close proximity of the first touch input with respect to the reference line.

12. The wireless communication terminal of claim 10, wherein the controller is further configured to display a contiguous portion of the image having the first scale while the image in the manipulation region is being compressed.

13. The wireless communication terminal of claim 10, wherein the controller is further configured to recognize a second touch input to alter the image in the manipulation region in response to the movement of both the first and second touch inputs relative to the reference line.

14. The wireless communication terminal of claim 10, wherein the manipulation region is determined by a user defined boundary.

15. The wireless communication terminal of claim 14, wherein the user defined boundary comprises a rectangle.

16. The wireless communication terminal of claim 10, wherein the manipulation region is not maintained depending on a first command provided by a user or a second command stored in the memory.

17. The wireless communication terminal of claim 10, wherein the image data comprises an image of a map.

18. The wireless communication terminal of claim 10, wherein each of the touch inputs comprises either a proximity touch or a contact touch on the touch screen by a pointer.

19. The wireless communication terminal of claim 18, wherein the pointer is a stylus or a finger of a user.

20. A method of displaying an image in a wireless communication terminal, the method comprising:

displaying at least a portion of the image having a first scale;

defining a manipulation region in the portion of the image in response to a first touch input; and

gradually removing or reinstating the portion of the image within the manipulation region in response to a movement of the first touch input relative to a reference line,

wherein the first scale of the image outside the manipulation region is maintained.

21. The method of claim 20 further comprising displaying an indicator for indicating the reference line.

22. The method of claim 20 further comprising storing a resulting image after gradually removing or reinstating the portion of the image within the manipulation region.

23. The method of claim 20 further comprising:

determining whether the removing of the portion of the image within the manipulation region is to be maintained; and

reinstating the portion of the image within the manipulation region based on the determination.

24. The method of claim 20 further comprising:

detecting a command for reinstating the portion of the image within the manipulation region; and

reinstating the portion of the image within the manipulation region depending on the determination.

26. The method of claim 20 further comprising displaying an indicator for indicating the reference line.

27. The method of claim 20 further comprising storing a resulting image after gradually compressing or expanding the portion of the image within the manipulation region.

28. The method of claim 20 further comprising:

determining whether the compressing or expanding of the portion of the image within the manipulation region is to be maintained; and

expanding the portion of the image within the manipulation region based on the determination.

29. The method of claim 20 further comprising:

detecting a command for expanding the portion of the image within the manipulation region; and

expanding the portion of the image within the manipulation region depending on the detection.

25. A method of displaying an image in a wireless communication terminal, the method comprising:

displaying at least a portion of the image having a first scale;

defining a manipulation region in the portion of the image in response to a first touch input; and

gradually compressing or expanding the portion of the image within the manipulation region in response a movement of the first touch input relative to a reference line,

wherein the first scale of the image outside the manipulation region is maintained.
