TOUCH PANEL DEVICE, DISPLAY DEVICE, TOUCH PANEL DEVICE CALIBRATION METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

A touch panel device (50) according to the present invention comprises: a detection unit (51) which detects an input operation on a touch panel (40) on the basis of a change of a capacitance of the touch panel (40); a calibration unit (53) which executes a calibration of the capacitance of the touch panel (40); and an assessment unit (54) which assesses whether the change of capacitance outside an input receiving region of the touch panel (40) is greater than or equal to a prescribed value.
