PROBLEM TO BE SOLVED: To accurately detect that a display screen has been depressed regardless of how a user depresses the display screen.SOLUTION: A reference value storage part 183 stores a sensor value in a timing in which any touch to a touch panel 110 is not detected as a reference value. A sensor value acquisition part 184 acquires the latest sensor value as necessary from among sensor values periodically acquired from a pressure sensor 160 by a pressure sensor controller 165. A subtraction part 185 subtracts the reference value stored by the reference value storage part 183 from the sensor value acquired by the sensor value acquisition part 184. A depression determination part 186 compares the subtraction result notified by the subtraction part 185 with a predetermined depression threshold, and when the subtraction result is not less than a predetermined depression threshold, determines that the touch panel 110 has been depressed. |
