A mobile communication terminal 100 has a touch panel unit 150 as an input unit. Touch detection is performed by scanning detection signals from the touch panel unit 150 at a given operation frequency. A radio device 120 performs communication such as cellular communication and reception of broadcast such as digital broadcast. When the radio device 120 performs radio transmission/reception operation, a touch detection processing unit 112 identifies an operation frequency of the touch panel unit 150 that is not interfered by the frequency of radio transmission/reception by the radio device 120 and a touch panel control unit 111 controls the touch panel unit 150 to scan it at that operation frequency. |
