Image display device and operating method for enlarging an image displayed in a region of a display and displaying the enlarged image variously

Abstract

An image display device including a display configured to display a first image is provided. The image display device includes a controller configured to generate a second image by enlarging a part of the first image displayed in a first region of the display and to control the display to display a part of the second image in the first region, and a sensor configured to sense a user input for moving the second image. In response to the user input, the controller is configured to control the display to move and display the second image, within the first region.

What is claimed is: 
     
         1 . An image display device comprising:
 a display; and   at least one processor configured to:
 control the display to display an image, 
 provide a window for displaying a part of the image based on first user input information received from a user interface device that is configured to receive user inputs for a magnification function, 
 control the display to display the part of the image in the window, wherein the part of the image is magnified to be displayed in the window, 
 change a location of the window on the display based on second user input information received from the user interface device, 
 control the display to display in the window a different part of the image, wherein the different part of the image is magnified to be displayed in the window and related to the location of the window, 
 fix the location of the window at a first location of the display, based on third user input information for fixing the window, the third user input information being received from the user interface device, and 
 control the display to display another part of the image in the window, according to fourth user input information, with the location of the window being fixed at the first location of the display, the fourth user input being received from the user interface device, 
   wherein the other part of the image is magnified to be displayed in the window and related to a second location of the display according to a type of the fourth user input information, and   wherein types of the fourth user input information include a positional input, a zooming input, and a selection of an identified object input.   
     
     
         2 . The image display device of  claim 1 ,
 wherein the user interface device is further configured to receive a directional key input, and   wherein the at least one processor is further configured to control so that the magnified other part of the image moves in the window in a direction corresponding to the received directional key input.   
     
     
         3 . The image display device of  claim 1 , wherein the display is further configured to display at least one of an icon or a scroll bar representing a movable direction of the magnified other part of the image in the window. 
     
     
         4 . The image display device of  claim 1 ,
 wherein the user interface device is further configured to receive the fourth user input for zooming in or out the magnified other part of the image in the window, and   wherein the at least one processor is further configured to:
 zoom in the magnified other part of the image in response to a received zoom-in input, or 
 zoom out the magnified other part of the image in response to a received zoom-out input. 
   
     
     
         5 . The image display device of  claim 1 , wherein the magnified other part of the image displayed in the window is identified from the image, based on a position of the window in the display.
