Mode of a touch panel (30) can be switched between first operation mode for detecting coordinate positions of a contact point, and second operation mode, in which the coordinate positions of the contact point are not detected but whether there is a contact or not is detected. An operation mode determining unit (22) determines the operation mode of the touch panel (30) to the first operation mode during a period of time when a display control unit (21) is displaying an image belonging to a first group, and during a period of time when the display control unit is displaying an image belonging to a second group, the display control unit determines the operation mode of the touch panel (30) to the second operation mode. An operation control unit (23) operates the touch panel (30) in the operation mode determined by means of the operation mode determining unit (22). |
