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.

A command processing apparatus, comprising:
- a first processor started irrespective of a state of a main power source;
- and a second processor started when the main power source is in an on state while stopped when the main power source is in an off state, wherein
- said first processor is provided with a first determiner which repeatedly determines whether or not a start command is issued by an external device when the main power source is in the off state, and a first changer which changes the state of the main power source to the on state when a determination result of said first determiner is updated from a negative result to a positive result, and
- the second processor is provided with a command processor which executes a process according to a command issued by the external device.
