A main processor of mobile phone changes from power saving state to active state for changing display in response to a sub processor for sensors, the main processor returning to the power saving state after changing the display. The main processor changes from power saving state to active state for storing information from the sub processor, the main processor returning to the power saving state after the storing function. The main processor selects the stored display data on the basis of the information from the sub processor to change display. The main processor receives and stores information from the sub processor in the boot up process or before finishing the operation. The sub processor is in the active state so as to control the sensor even in a case where the main processor is in the power saving state.
