Abstract

An input device outputs coordinate information of an input position detected by a touch panel to an upper-level device as it is, without change, as long as the value of pressure on the input position is smaller than a second pressure threshold. The input device stores coordinate information of the input position detected while the value of pressure on the input position is between a first pressure threshold and the second pressure threshold in the memory, and outputs the coordinate information stored in the memory, instead of the coordinate information detected by the touch panel to an upper-level device if the value of pressure on the input position reaches or exceeds the second pressure threshold.
