Abstract
A touch panel device including a touch panel unit having transparent electrodes arranged in an X and Y direction; an electrical potential detection unit configured to scan the electrodes and detect electrostatic capacitance values in the X and Y direction; an object type detection unit configured to detect a type of object that has come within proximity to the surface of the touch panel unit on the basis of a distribution shape of the electrostatic capacitance values detected by the electrical potential detection unit; and an operation position detection unit configured to, based on the detected type of object, change a data extraction threshold value used to calculate a touch position of the object, and detect coordinates of a position at which the object has come within proximity to or come into contact with the surface of the touch panel unit based on the changed data extraction threshold value.
