A method of outputting an input position of a touch panel is provided which can output an input position intended by an operator even if two or more different input positions are detected. When an input operation on a position different from a first input position is detected in a scan cycle after output of the first input position, the input position where the new input operation is detected is output as a second input position. Even if input operations on two or more different positions are simultaneously detected, only one input position is output.
