An electronic device includes a first processing device, a second processing device, and a power state control unit. The power state control unit controls a power state of the electronic device. The power state includes a normal state and a power-saving state. The first processing device ensures the execution of the process according to the received data. The second processing device ensures the execution of the process according to the received data which is not processed in the first processing device. When a temporary wake up of the electric power supply to the second processing device is intermittently repeated in the power-saving state, the power state control unit determines a time interval from a termination of the temporary wake up to a start of a subsequent temporary wake up based on a specific condition during the temporary wake up. According to the invention, power consumption of the electronic device can be reduced.
