         4 . The apparatus according to  claim 1 , wherein
 the display control unit performs the display control processing for changing the scaling factor of the first page so as to zoom in on the first page.   
     
     
         5 . The apparatus according to  claim 1 , wherein the display control unit performs the display control processing for displaying the second page at default size or in an overview. 
     
     
         6 . A display control method for causing a display provided in an apparatus to display a plurality of pages, the display control method comprising:
 first displaying a first page among the plurality of pages, by changing a scaling factor of the first page from a given scaling factor to a changed scaling factor in a whole of a given area of the display without changing a size of the given area after detecting that a first operation has been performed in an area of the first page displayed on the display; and   second displaying, when detecting a second operation to the first page for displaying a second page relating to the first page among the plurality of pages instead of the first page, after a scaling factor of the first page has been changed from the given scaling factor to the changed scaling factor in the whole of the given area in response to the first operation, the second page on the display so as to display the second page with the given scaling factor in the whole of the given area.   
     
     
         7 . The display control method according to  claim 6 , wherein
 a touch panel is provided in the display, and   the first operation and the second operation are detected by using the touch panel.   
     
     
         8 . The display control method according to  claim 6 , wherein consecutively performing the first operation is capable of changing the scaling factor of the first page to any one of a plurality of given scaling factors and one of the plurality of given scaling factors. 
     
     
         9 . The display control method according to  claim 6 , wherein
 the first operation includes a double tap operation performed in an area of the first page.   
     
     
         10 . The display control method according to  claim 6 , wherein the changing changes the scaling factor of the first page so as to zoom in on the first page. 
     
     
         11 . The display control method according to  claim 6 , wherein the second displaying displays the second page at default size or in an overview. 
     
     
         12 . A non-transitory computer readable storage medium that stores a program for causing a computer to perform a process for displaying a plurality of pages on a display, the process comprising:
 first detecting that a first operation has been performed in an area of a first page displayed on the display among the plurality of pages;   changing a scaling factor of the first page from a given scaling factor to a changed scaling factor in a whole of a given area on the display without changing a size of the given area based on the first detecting;   second detecting that a second operation has been performed in an area of the first page after the changing; and   displaying a second page relating to the first page among the plurality of pages with the given scaling factor in the whole of the given area based on the second detecting.   
     
     
         13 . The non-transitory computer readable storage medium according to  claim 12 , wherein
 the first operation includes a double tap operation performed in an area of the first page.   
     
     
         14 . The non-transitory computer readable storage medium according to  claim 12 , wherein the changing changes the scaling factor of the first page so as to zoom in on the first page.
