Touch panel device, touch panel device control method, and non-transitory tangible computer-readable storage medium having the program stored therein

A method of controlling a touch panel device including a capacitive touch panel,

• wherein the touch panel device comprises
• a driving unit configured to send a drive pulse signal to the touch panel, and
• a receiving unit configured to receive sense signals based on an operated position on the touch panel, the sense signals being outputted from the touch panel,
• the touch panel device control method comprising:
• a driving control step of controlling the driving unit so that the driving unit sends a given number of pulses of the drive pulse signal at a given frequency;
• a signal strength obtaining step of obtaining strengths of the sense signals received by the receiving unit;
• a signal strength adjusting step of, among the strengths of the sense signals corresponding to respective pulses of the drive pulse signal, adjusting strength of a sense signal that is equal to or greater than a threshold, to a first adjustment value, and adjusting strength of a sense signal that is less than the threshold, to a second adjustment value smaller than the first adjustment value;
• and
• an operated position obtaining step of obtaining the operated position based on sense signals, of the sense signals, in which an average of the adjusted strengths of the sense signals corresponding to the respective pulses of the drive pulse signal is equal to or greater than a given average.
