An electronic device includes a touch panel and a position detection circuit operable to output a position signal indicating a position at which the touch panel operated with an object. The detection circuit is operable perform a correction process to capacitance measurement values of electrodes of the touch panel to provide capacitance correction values. The detection circuit is operable to determine whether or not the electronic device is in a holding status in which the electronic device is held based on the capacitance measurement values or the capacitance correction values. The detection circuit is operable to perform a calibration process to correct the correction process if determining that the electronic device is in the holding status. The detection circuit is operable to output the position signal based on the capacitance measurement values or the capacitance correction values. This electronic device can avoid a false detection in approaching detection. |
