In the portable terminal device disclosed herein, when the finger of the user gradually approaches, an estimated coordinate which is the position of the finger, and an estimated distance which is the distance of the finger to the touch panel is determined from the capacitance value between the finger and the touch panel, while capacitance distribution information indicating the distribution of the capacitance value is created. When the created capacitance distribution information is similar to the configured capacitance distribution information, of the plurality of icons displayed on the touch panel, the target icon, which is arranged at the estimated coordinate, is displayed on the touch panel in a size larger than a standard display size. Hereby, icons being displayed on the touch panel are enlarged only when sensing the approach of the finger of the user to the touch panel. Thus, it is possible to avoid erroneous operations and to achieve increased operability for the user. |
