Abstract
A position indicated by a user with a finger or a stylus can be detected even in a case where an edge of a hand on a little finger side, a wrist or the like touches a touch panel. An input device acquires a touch intensity change signal that indicates a change of touch intensity at a plurality of measuring positions on a touch panel, applies a frequency filter, which suppresses a frequency component of the touch intensity change signal generated by a touch other than by a finger or a stylus, to the touch intensity change signal at at least one of the measuring positions, and generates data of a position indicated by a user on the touch panel based on the touch intensity change signal, to which the frequency filter is applied, at the respective measuring positions.
