PROBLEM TO BE SOLVED: To provide a framework for making it possible to flexibly changing the magnification of data in an enlarged display area by user's touch operation.SOLUTION: An information processing apparatus for displaying data on a display including a touch panel, displays a magnification change frame indicating an area for which a display magnification is to be changed out of an area in which the data is displayed on the data upon receiving an indication to display the magnification change frame via the touch panel. Furthermore, while receiving the indication for displaying the magnification change frame, the information processing apparatus displays the magnification change frame while increasing or reducing a size of the magnification change frame step by step. Moreover, if not receiving the indication for displaying the magnification change frame, the information processing apparatus stops processing for increasing or reducing the size of the magnification change frame step by step. Next, the information display apparatus changes the display magnification of data in the magnification change frame upon receiving an indication to change the display magnification of the data in the magnification change frame. |
