Abstract
Capacitances caused by respective electrodes of a touch panel, which is used to detect an instruction position of the user based on a change in capacitance, are measured, and it is determined whether or not a difference between the measured value and a reference value is larger than a threshold. When it is determined that the difference is larger than the threshold, a portion corresponding to the electrode on the touch panel is detected as the instruction position of the user. After detection, when the difference continues for a predetermined period time, the measured value is set as a new reference value.
