Abstract

A central processing unit (CPU) monitors whether a predetermined event (pressing of a sleep release button, an incoming call, an alarm ring sound, or the like) is generated. When the predetermined event is generated, a sensitivity detection unit sets a sensitivity threshold value for input detection to a threshold value of a high-sensitivity mode, and the CPU displays a screen corresponding to the event. When an input operation is performed on the screen, the sensitivity detection unit resets a subsequent sensitivity threshold value according to input sensitivity information detected when the input operation is performed.
