Wireless communication terminal and method for displaying image data

A wireless communication terminal, comprising:

• a touch screen configured to display information and recognize received touch input;
• a memory configured to store image data;
• and
• a controller configured to:
• 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.

A method of displaying an image on a touch screen of a wireless communication terminal, the method comprising:

• displaying at least a portion of the image having a first scale on the touch screen;
• recognizing a touch input received via the touch screen to define a manipulation region associated a defined reference line associated with the displayed at least a portion of the image;
• gradually removing a portion of the at least a portion of the image within the manipulation region into the reference line or gradually reinstating a portion of the at least a portion of the image within the manipulation region from the reference line 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
• scrolling portions of the image not displayed on the touch screen prior to the gradual removal of the portion of the at least a portion of the image in the manipulation region into the reference line to be displayed on the touch screen in response to the gradual removal of the portion of the at least a portion of the image in the manipulation region into the reference line or scrolling portions of the image displayed on the touch screen in response to the gradual removal of the portion of the at least a portion of the image in the manipulation region into the reference line to remove from the touch screen in response to the reinstating of the portion of the at least a portion of the image in the manipulation region from the reference line.

A method of displaying an image on a touch screen of a wireless communication terminal, the method comprising:

• displaying at least a portion of the image having a first scale on the touch screen;
• recognizing a touch input received via the touch screen to define a manipulation region in the portion of the image associated with a defined reference line associated with the displayed at least a portion of the image;
• gradually compressing or gradually expanding a portion of the at least a portion of the image within 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 the manipulation region;
• and
• scrolling 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 scrolling 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.
