  • Publication number: 20170160864
    Abstract: A terminal may be provided that includes: a touch screen; a processor; and a controller. When a touch is input to the touch screen, the processor detects a position of the touch and a magnitude of a pressure of the touch and transfers information on the touch position and information on the magnitude of the touch pressure to the controller. Based on the magnitude of the touch pressure, the controller changes an image which is displayed on a change target region around the touch position, and displays the changed image on the touch screen. The change target region includes a first region and a second region disposed within the first region, an image enlarged perpendicularly to the boundary of the first region is displayed on the first region, and an image reduced perpendicularly to the boundary of the second region is displayed on the second region.
