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.

communicate with the memory and the touch screen;

control the touch screen to display at least a portion of an image having a first scale;

recognize a first touch input received via the touch screen to define a manipulation region associated with a defined reference line associated with the displayed at least a portion of the image;

control the touch screen to gradually compress or expand a portion of the at least a portion of the image in the manipulation region in response to a detected movement of the first touch input relative to the reference line while maintaining the first scale of the at least a portion of the image that is displayed outside of the manipulation region; and

control the touch screen to scroll portions of the image not displayed on the touch screen prior to the gradual compression of the portion of the at least a portion of the image in the manipulation region to be displayed on the touch screen in response to the gradual compression of the portion of the at least a portion of the image in the manipulation region or to scroll portions of the image displayed on the touch screen in response to the gradual compression of the portion of the at least a portion of the image in the manipulation region to remove from the touch screen in response to the expansion of the portion of the at least a portion of the image in the manipulation region.

13. The wireless communication terminal of claim 12, wherein the controller is further configured to control the touch screen to remove the portion of the at least a portion of the image that is displayed in the manipulation region when the first touch input is in close proximity to the reference line.

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

15. The wireless communication terminal of claim 12, wherein the controller is further configured to recognize a second touch input to alter the at least a portion of the image in the manipulation region in response to the movement of both the first touch input and second touch input relative to the reference line.

16. The wireless communication terminal of claim 12, wherein the manipulation region is determined by a user defined boundary.

17. The wireless communication terminal of claim 16, wherein the user defined boundary comprises a rectangle.

18. The wireless communication terminal of claim 12, wherein the controller is further configured to cease defining the manipulation region based on a first command provided by a user or a second command stored in the memory.

19. The wireless communication terminal of claim 12, wherein the image data comprises an image of a map.

20. The wireless communication terminal of claim 12, wherein the received touch input comprises a proximity touch or a contact touch on the touch screen by a pointer.
