1. A user interface device operable to perform a display function of displaying an image, a touch panel function of outputting successive locations of the user'"'"'s finger contact point on a touch screen over time, and a function of scrolling an integral image being displayed, in response to a drag motion performed on the touch screen with the user'"'"'s finger, the user interface device comprising:

  • a pressing-force sensor detecting a pressing force with which the finger presses the touch screen;

    a motion-recognizing unit configured to determine whether or not the drag motion has ended;

    a scroll-rate determining unit configured to be operable in response to the motion-recognizing unit determining that the drag motion has ended, to determine a post-drag scroll rate that is a scroll rate of scrolling to be performed subsequently to the drag motion, based on a magnitude of the pressing force detected by the pressing-force sensor at an end time of the drag motion and/or during a period of time after the end time of the drag motion; and

    a scroll controller configured to further scroll the integral image being displayed, at the determined post-drag scroll rate, after scrolling invoked by the drag motion ends.
