Apparatus and method for displaying an enlarged target region of a reproduced image

Abstract

An apparatus and a method for selecting and displaying a particular region in a displayed image. A user selects a target region in an image displayed on an image reproduction apparatus, an image of the selected target region is enlarged and displayed in a window, which the user can adjust a generation position, a size, a zoom magnification, and a resolution thereof. The image reproduction apparatus tracks a target object in the target region, and enables the user to continuously view the target object in the window.

1 . A method for displaying a enlarged target region of an image reproduced by an image reproduction apparatus, the method comprising:
 setting generation information on a window to be displayed on top of the reproduced image;   designating a target region in the reproduced image;   generating the window using the generation information on the window; and   displaying an enlarged image of the designated target region in the generated window.   
     
     
         2 . The method as claimed in  claim 1 , wherein the generation information on the window includes at least one of a generation position, a size, a zoom magnification, and a resolution of the window. 
     
     
         3 . The method as claimed in  claim 1 , further comprising:
 determining if the window overlaps the designated target region; and   changing a position of the window, when the window overlaps the designated target region.   
     
     
         4 . The method as claimed in  claim 1 , wherein displaying the enlarged image of the designated target region comprises:
 extracting a target object in the designated target region;   tracking the extracted target object; and   continuously displaying the tracked target object in the window.   
     
     
         5 . The method as claimed in  claim 1 , wherein a user sets the generation information on the window using a setting menu or a touch pen. 
     
     
         6 . An apparatus for displaying an enlarged target region of a reproduced image, the apparatus comprising:
 a window information generation unit for setting generation information on a window to be displayed on top of the reproduced image;   a target region selection unit for receiving, from a user, a target region in the reproduced image;   a window generation unit for generating the window using the generation information on the window; and   an image processing unit for displaying an image of the target region in the generated window.   
     
     
         7 . The apparatus as claimed in  claim 6 , wherein the generation information on the window comprises at least one of a generation position, a size, a zoom magnification, and a resolution of the window. 
     
     
         8 . The apparatus as claimed in  claim 6 , further comprising:
 an exceptional situation processing unit for determining if the window overlaps the target region, and changing a position of the window when the window overlaps the target region.   
     
     
         9 . The apparatus as claimed in  claim 6 , wherein the image processing unit extracts a target object in the target region, and tracks the extracted target object to continuously display the tracked target object in the window. 
     
     
         10 . The apparatus as claimed in  claim 6 , wherein a user sets the generation information on the window using a setting menu or a touch pen.
