An object of the present invention is to provide a device, a method, and a computer-readable recording medium, all of which improve the operability for enlarging or reducing an image. A controller sets a scale factor for enlarging or reducing a display image displayed on a touch-screen display, in response to detecting a touch to a plurality of points on the touch-screen display. The controller enlarges or reduces the display image, based on a gesture after touching the plurality of points (multi-touch gesture), and the scale factor thus set. |
