Abstract:
An input device includes a touch panel having a plurality of transparent electrodes disposed side by side, a hover signal generation unit for generating a hover signal used to detect a height of an indicator located above a surface of the touch panel to input the hover signal to the plurality of electrodes, an XY position detection unit for detecting an X position and a Y position of the indicator based on a signal component that appears on each of the electrodes, and a height detection unit for detecting a height of the indicator based on a signal component that appears on each of the electrodes. The height detection unit performs a correction to the height of the indicator when the XY position of the indicator is within a peripheral portion of the touch panel.
