Abstract

Thumbnails included in an area designated by a pinch gesture are all specified. If it is not true that “the thumbnails included in the designated area are all displayed in the selected style” (S 2004, No), the thumbnails included in the designated area are all displayed in the selected style (S 2005 ), and the status is set to selected state (S 2006 ). If it is true that “the thumbnails included in the designated area are all displayed in the selected style” (S 2004, Yes), the thumbnails included in the designated area are all displayed in unselected style (S 2007 ), and the status is set to unselected state (S 2008 ). If the gesture is continuously changed to a pinch-out gesture or a pinch-in gesture (S 2010, No), the selected area or the unselected area are expanded or reduced depending on the status (S 2014, S 2015 ).

         3 . The image display apparatus according to  claim 2 , wherein
 the second control section applies to the at least one item on the display area, a style corresponding to the rearrangement.   
     
     
         4 . The image display apparatus according to  claim 3 , wherein
 the at least one item includes a first item that will not be displayed on the display area upon/after the completion of the zoom-in/out operation, and   the second control section applies to the first item, a first style that differs from a style of an item that will remain displayed on the display area upon/after the completion of the zoom-in/out operation.   
     
     
         5 . The image display apparatus according to  claim 3 , wherein
 the at least one item includes: a second item that will be displayed by a limit of the display area upon/after the completion of the zoom-in/out operation, and   the second control section applies to the second item, a second style that differs from a style of an item that will not be displayed by the limit of the display area upon/after the completion of the zoom-in/out operation.   
     
     
         6 . The image display apparatus according to  claim 3 , wherein
 the at least one item includes:
 a first item that will not be displayed on the display area upon/after the completion of the zoom-in/out operation, and the second control section applies to the first item, a first style that differs from a style of an item that will remain displayed on the display area upon/after the completion of the zoom-in/out operation; and 
 a second item that will be displayed by a limit of the display area upon/after the completion of the zoom-in/out operation, and the second control section applies to the second item, a second style that differs from a style of an item that will not be displayed by the limit of the display area upon/after the completion of the zoom-in/out operation. 
   
     
     
         7 . The image display apparatus according to  claim 2 , wherein
 the second control section applies the specific style to the at least one item so that a transition during which the at least one item is being rearranged is visualized.   
     
     
         8 . The image display apparatus according to  claim 1 , wherein
 the zoom-in/out operation includes an operation which is enable a distance between coordinates of two points designated by a designating operation on the touch screen to be changed, and   in response to detecting the zoom-in/out operation,   if the distance is shorter than a predetermined value, zooming-out of the plurality of items is not permitted.   
     
     
         9 . The image display apparatus according to  claim 1 , wherein
 the zoom-in/out operation includes an operation which is enable a distance between coordinates of two points designated by a designating operation on the touch screen to be changed, and   in response to detecting the zoom-in/out operation,   if the distance is longer than a predetermined value, zooming-in of the plurality of items is not permitted.   
     
     
         10 . The image display apparatus according to  claim 1 , wherein
 the at least one item includes a third item that is located around a coordinate with respect to the zoom-in/out operation, and in response to detecting the zoom-in/out operation, the second control section applies to the third item, a distinguishable style.   
     
     
         11 . The image display apparatus according to  claim 10 , wherein
 the second control section retains the distinguishable style for a predetermined period after the zoom-in/out operation is completed.   
     
     
         12 . The image display apparatus according to  claim 10 , wherein
 before the zoom-in/out operation is completed, if the sizes of the plurality of items have not been changed for a predetermined period, the second control section terminates applying to the third item, the distinguishable style.   
     
     
         13 . The image display apparatus according to  claim 1 , wherein
 the plurality of items includes a plurality of thumbnails,   the image display apparatus comprises:
 a selection mode where selection of a thumbnail to be a target subject to certain processing from among the plurality of thumbnails according to a designating operation on the touch screen is enabled, and 
 a non-selection mode where zooming-in/out of the plurality of thumbnails according to the zoom-in/out operation is enabled, 
   the designating operation and the zoom-in/out operation include designating two points on the touch screen and pinching the two points, and   the selection mode and the non-selection mode are switchable to each other according to a predetermined switching operation.   
     
     
         14 . The image display apparatus according to  claim 13 , wherein
