Mobile phone

摘要

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.

1. A mobile phone comprising:
a telephone function part; a display unit; a main processor which controls the telephone function part and the display unit; a sensor; and a sensor control sub processor which controls the sensor and communicates information with the main processor, wherein the main processor can change between an active state for controlling the telephone function part and a power saving state, wherein the main processor changes from the power saving state to the active state if it is necessary for the main processor to change a display on the display unit in response to information from the sensor control sub processor, and changes from the active state to the power saving state if there is no other task after the display is changed, and wherein the information transmitted from the sensor control sub processor to the main processor includes information detected by the sensor while the main processor was in the power saving state.
