  • Patent number: 9292142
    Abstract: The electronic device has a display section with a display surface; and a touch panel that is provided while being superimposed on the display section and that can detect an area occupied by an indicator in which the occupied area is on a predetermined plane which is approximately parallel to and spaced apart by a predetermined distance from the display surface of the display section. When flattening of the area occupied by the indicator is smaller than a threshold value in which the occupied area is on the predetermined plane spaced apart from the display surface of the display section by a predetermined distance, coordinates of the center of the area are made valid. When the flattening is greater than the threshold value, the coordinates of the center of the area are made invalid.

  • Patent number: 9134836
    Abstract: Provided is an electronic device. The electronic device includes a planar display unit, and a touch panel which is disposed so as to overlap the display unit and is capable of detecting a vertical distance between two-dimensional coordinates along a surface of the display unit and a finger. Resolution of the two-dimensional coordinates becomes finer as the vertical distance decreases. Thus, even when the operating finger is immobilized in a state where the electronic device is fixed, a display of a pointer is not wobbled or a display of a screen is not wobbled. In addition, when a line is drawn using a drawing mode, the line is not displayed jaggedly.
