PROBLEM TO BE SOLVED: To provide a mobile phone in which effective power saving is implemented.SOLUTION: If an application processor which controls a telephone function section and a display section is in a power saving state when changing an indication in accordance with sensor detection information or sensor operation information from a sensor control microcomputer, the application processor is shifted to an active state and after the indication is changed, the application processor is shifted to the power saving state. If the application processor is in the power saving state when storing information from the sensor control microcomputer, the application processor is shifted to the active state and after the information is stored, the application processor is shifted to the power saving state. An indication-off state is continued excepting display timing. The application processor selects stored display data based on information from the sensor control microcomputer and changes the indication on the display section. The application processor receives and stores information of the sensor control microcomputer in starting-up or before operation end. The sensor control microcomputer controls sensors by being in an active state even while the application processor is in the power saving state. |
