Abstract
A communication apparatus comprises a close proximity wireless communication unit which is able to perform close proximity wireless communication with an external apparatus; a power control unit which starts control of power supply of the communication apparatus when the close proximity wireless communication unit receives electromagnetic waves from the external apparatus; and a control unit which executes shutdown processing for reducing power to each block controlled by the power control unit, wherein when the shutdown processing is executed, the control unit disables the close proximity wireless communication unit before start of the shutdown processing.
Claims18
A communication apparatus comprising:
- a close proximity wireless communication circuit configured to be able to perform close proximity wireless communication with an external apparatus;
- at least one processor configured to function as:
- a power control unit configured to start control of power supply of the communication apparatus when the close proximity wireless communication circuit receives electromagnetic waves from the external apparatus;
- and
- a control unit configured to execute shutdown processing for reducing power to each block controlled by the power control unit,
- wherein when the shutdown processing is executed, the control unit disables the close proximity wireless communication circuit before start of the shutdown processing,
- wherein when the shutdown processing is complete, the close proximity wireless communication circuit is enabled.
A communication apparatus comprising:
- a close proximity wireless communication circuit configured to be able to perform close proximity wireless communication with an external apparatus;
- at least one processor configured to function as:
- a power control unit configured to start power supply processing of the communication apparatus when the close proximity wireless communication circuit receives electromagnetic waves from the external apparatus;
- and
- a control unit configured to execute shutdown processing for reducing power to each block controlled by the power control unit,
- wherein the shutdown processing and the power supply processing are not executed at the same time,
- wherein when the shutdown processing is complete, the close proximity wireless communication circuit is enabled.
A control method of a communication apparatus having a close proximity wireless communication unit configured to be able to perform close proximity wireless communication with an external apparatus, the method comprising:
- a power control step of starting control of power supply of the communication apparatus when the close proximity wireless communication unit receives electromagnetic waves from the external apparatus;
- and
- a control step of executing shutdown processing for reducing power to each unit controlled in the power control step,
- wherein when the shutdown processing is executed, the close proximity wireless communication unit is disabled in the control step before the shutdown processing starts,
- wherein when the shutdown processing is complete, the close proximity wireless communication is enabled.
A control method of a communication apparatus having a close proximity wireless communication unit configured to be able to perform close proximity wireless communication with an external apparatus, the method comprising:
- a power control step of starting power supply processing of the communication apparatus when the close proximity wireless communication unit receives electromagnetic waves from the external apparatus;
- and
- a control step of executing shutdown processing for reducing power to each block controlled in the power control step,
- wherein the shutdown processing and the power supply processing are not executed at the same time,
- wherein when the shutdown processing is complete, the close proximity wireless communication unit is enabled.
A non-transitory computer-readable storage medium which stores a program for causing a computer to execute a method, the method comprising:
- a power control step of starting control of power supply of the communication apparatus when the close proximity wireless communication unit receives electromagnetic waves from the external apparatus;
- and
- a control step of executing shutdown processing for reducing power to each unit controlled in the power control step,
- wherein when the shutdown processing is executed, the close proximity wireless communication unit is disabled in the control step before the shutdown processing starts,
- wherein when the shutdown processing is complete, the close proximity wireless communication unit is enabled.
A non-transitory computer-readable storage medium which stores a program for causing a computer to execute a method, the method comprising:
- a power control step of starting power supply processing of the communication apparatus when the close proximity wireless communication unit receives electromagnetic waves from the external apparatus;
- and
- a control step of executing shutdown processing for reducing power to each block controlled in the power control step,
- wherein the shutdown processing and the power supply processing are not executed at the same time,
- wherein when the shutdown processing is complete, the close proximity wireless communication unit is enabled.
