Abstract
An electrostatic input device includes a plurality of electrostatic sensor electrodes arrayed in one direction, a measurement circuit configured to measure a capacitance between each of the plurality of electrostatic sensor electrodes and an operation body, a storage unit, and a control unit configured to calculate a position of the operation body based on a capacitance correction value obtained by subtracting a reference value from the capacitance measured by the measurement circuit, determine whether the operation body is close to at least one of the plurality of electrostatic sensor electrodes based on the capacitance correction value, and calculate a direction of movement and an amount of movement of the operation body.
