Electronic apparatus, wireless power supply system, and control methods thereof

A control method of an electronic apparatus that includes an antenna,

• the control method comprising:
• authenticating, after a power-supply target electronic apparatus is detected through a first polling, for the power-supply target electronic apparatus;
• notifying, when the power-supply target electronic apparatus is authenticated, the power-supply target electronic apparatus of a start of foreign object detection processing;
• executing, after the notifying, the foreign object detection processing to detect a presence of a foreign object that is not a power supply target through a second polling performed for a predetermined period;
• and
• controlling power supply from the antenna to the power-supply target electronic apparatus in a non-contacting manner, based on a result of the foreign object detection processing.

A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a control method of an electronic apparatus that includes an antenna,

• the control method comprising:
• authenticating, after a power-supply target electronic apparatus is detected through a first polling, for the power-supply target electronic apparatus;
• notifying, when the power-supply target electronic apparatus is authenticated, the power-supply target electronic apparatus of a start of foreign object detection processing;
• executing, after the notifying, the foreign object detection processing to detect a presence of a foreign object that is not a power supply target through a second polling performed for a predetermined period;
• and
• controlling power supply from the antenna to the power-supply target electronic apparatus in a non-contacting manner, based on a result of the foreign object detection processing.
