Method and apparatus for displaying photo on screen having any shape

Abstract

Provided are a method and an apparatus for displaying a photo on a screen having any shape. The method includes: extracting photographing information about a photo having a first shape; adjusting the photo for display with a shape optimized for a screen having a second shape, based on the extracted photographing information; and displaying the adjusted photo on the screen.

What is claimed is: 
     
         1 . A method of processing a photo for display on a screen of a display device, the method comprising:
 determining photographing information about an individual photo having a first shape, wherein the photographing information comprises information for determining an important region in the individual photo;   automatically adjusting, by an image processor, the individual photo for display with a shape corresponding to a screen having a second shape so as to display the important region in the screen, based on the determined photographing information, wherein the second shape is different from the first shape, and if the first shape is rectangular, then the second shape is not rectangular; and   outputting the adjusted photo.   
     
     
         2 . The method of  claim 1 , wherein the determining of the photographing information comprises obtaining the photographing information from a digital photo file corresponding to the photo having the first shape. 
     
     
         3 . The method of  claim 2 , wherein the determining of the photographing information further comprises generating, using a digital photographing device, the digital photo file from the photo having the first shape, and storing the generated digital photo file. 
     
     
         4 . The method of  claim 1 , wherein:
 the photographing information comprises at least one of lens information, focal length information, and focus information; and   the adjusting of the photo comprises determining whether the photo is a short range photo based on the photographing information.   
     
     
         5 . The method of  claim 4 , wherein the determining of whether the photo is the short range photo comprises:
 determining a region having the focus information in the photo; and   determining whether the photo is the short range photo based on the determined region.   
     
     
         6 . The method of  claim 5 , wherein the determining of whether the photo is the short range photo based on the determined region comprises determining that the photo is a long range photo if the focus information is distributed throughout the photo, and determining that the photo is the short range photo if the focus information is limited to a partial region of the photo. 
     
     
         7 . The method of  claim 4 , wherein:
 the determining of whether the photo is the short range photo comprises determining whether the photo is the short range photo based on the lens information and a view angle determined according to the focal length information of the photo; and   the lens information is information about a lens used to take the photo.   
     
     
         8 . The method of  claim 4 , wherein the adjusting of the photo further comprises adjusting the photo to be displayed throughout the screen if the photo is a long range photo. 
     
     
         9 . The method of  claim 4 , wherein the adjusting of the photo further comprises zooming in the photo so that a region having the focus information in the photo is located in a center of the screen, if the photo is the short range photo according to the determining. 
     
     
         10 . The method of  claim 8 , wherein the adjusting of the photo comprises, if the photo is displayed while being inscribed in the screen, filling a remaining portion of the screen excluding the photo with an image obtained by copying at least a part of the photo. 
     
     
         11 . The method of  claim 10 , wherein the filling of the remaining portion comprises filling the remaining portion with a background identical to a peripheral portion of the photo. 
     
     
         12 . The method of  claim 1 , wherein the screen is an image viewing region having the second shape in a display device, the second shape being different from the first shape or equivalent to the first shape. 
     
     
         13 . The method of  claim 1 , wherein the second shape is a non-tetragonal shape. 
     
     
         14 . A computer readable recording medium having recorded thereon a program executable by a computer for performing the method of  claim 1 . 
     
     
         15 . An apparatus for displaying a photo on a screen, the apparatus comprising:
 an image extractor configured to extract photographing information about an individual photo having a first shape, wherein the photographing information comprises information for determining an important region in the individual photo;   an image processor configured to automatically adjust the individual photo for display with a shape corresponding to a screen having a second shape so as to display the important region in the screen, based on the extracted photographing information, wherein the second shape is different from the first shape, and if the first shape is rectangular, then the second shape is not rectangular; and   a displayer configured to display the adjusted photo on the screen.   
     
     
         16 . The apparatus of  claim 15 , further comprising:
 a storage unit configured to generate, using a digital photographing device, a digital photo file from the photo having the first shape, and store the generated digital photo file,   wherein the image extractor obtains the photographing information from the digital photo file.   
     
     
         17 . The apparatus of  claim 15 , wherein:
 the photographing information comprises at least one of lens information, focal length information, and focus information; and   the image processor determines whether the photo is a short range photo based on the photographing information.   
     
     
         18 . The apparatus of  claim 17 , wherein the image processor determines a region having the focus information in the photo, and determines whether the photo is the short range photo based on the determined region. 
     
     
         19 . The apparatus of  claim 18 , wherein the image processor determines that the photo is a long range photo if the focus information is distributed throughout the photo, and determines that the photo is the short range photo if the focus information is limited to a partial region of the photo.
