Abstract: An electronic device having a clock portion for counting time and having the time on the clock portion set based on time information acquired from outside has a notification portion that communicates information of the time counted by the clock portion to an external device via a physical line. Alternatively, an electronic device has a first clock portion counting time and an acquisition portion that acquires, from an external device having a second clock portion for counting time and having the time on the second clock portion set based on time information acquired from outside, information of the time counted by the second clock portion via a physical line, and the time on the first clock portion is set based on the information acquired by the acquisition portion.

Abstract: A digital camera is provided with: a sub CPU started irrespective of a state of an SW group; and a main CPU and an HDMI-CPU which are started when the SW group is in an on state while stopped when the SW group is in an off state. The sub CPU repeatedly determines whether or not a wake-up command is issued from a digital television connected via an HDMI cable when the SW group is in the off state. Furthermore, the sub CPU changes the state of the SW group to the on state when a determination result relating to presence or absence of the wake-up command is updated from NO to YES. The HDMI-CPU and the main CPU that are started thereby execute a process according to a command issued from the digital television.
