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.
