An electronic apparatus a determining unit configured to determine a target object that a user is paying attention to, a detecting unit configured to detect a plurality of types of detection information on the target object, a referring unit configured to refer to reference information associated with the target object, a presenting unit configured to present at least one of the plurality of types of detection information, and a control unit configured to determine the at least one of the plurality of types of detection information presented by the presenting unit, based on the reference information and the plurality of types of detection information.

Electronic apparatus and control method of the same

An electronic device includes a control unit and a communication unit that is capable of communicating with a power supply device. The control unit determines whether or not a predetermined message relating to an authentication communication is received from the power supply device via the communication unit, and controls the electronic device to limit operation of the electronic device in a case where the predetermined message is received from the power supply device via the communication unit.

Electronic device and method

An electronic apparatus includes a display unit, a determining unit configured to determine a target object that a user is paying attention to, an acquiring unit configured to acquire a plurality of types of information on the target object, a referring unit configured to refer to reference information associated with the target object, and a control unit configured to determine the at least one of the plurality of types of information based on the reference information and the plurality of types of information, the display unit displays the at least one of the plurality of types of information and image data stored in a memory, and the reference information is past information of each of the plurality of types of information.

An electronic device includes a first control unit, a voltage conversion unit, a power supply unit, and a second control unit. The voltage conversion unit converts the voltage supplied from a power supply device into an output voltage, depending on a voltage of a battery. The power supply unit uses power supplied from the power supply device to charge the battery and supply power to the first control unit. The second control unit controls the power supply unit, to supply power to the first control unit via the voltage conversion unit, in a case where a duty of PWM control exceeds a predetermined threshold, and to supply power to the first control unit without passing through the voltage conversion unit, in a case where the duty of PWM control is less than the predetermined threshold.

Electronic device and control method

An electronic device includes a connection unit including a first terminal for receiving power from a power supply apparatus and a second terminal for receiving power supply capability of the power supply apparatus, a communication control unit that performs communication with the power supply apparatus via the second terminal, and a power control unit that performs a process for limiting power supplied from the power supply apparatus to a predetermined power or less in a case where the power supply capability is received from the power supply apparatus.

Electronic device

An electronic device includes a connection unit that receive power from a power supply apparatus via a first terminal, a communication control unit that communicates with the power supply apparatus via a second terminal to receive power supply capability information of the power supply apparatus, and a control unit that disables activation of the electronic device before the communication control unit receives a predetermined notification from the power supply apparatus.

Electronic device, method, and storage medium

An electronic device includes an interface unit having a first terminal and a second terminal, a determination unit that determines a power supply capability of an external device in accordance with a voltage of the second terminal, a power switching unit that determines a current in response to the voltage of the second terminal and a power supply capability of the external device, and a control unit that enables power supply from the external device to be performed with the determined current.

Electronic device with power source control ciruitry for determining a current

An electronic device includes a power receiving unit that receives power from a power supply apparatus, a type determination unit that determines a type of the power supply apparatus, a capability determination unit that determines a power supply capability of the power supply apparatus, and a control unit. The control unit limits or stops power to be received from the power supply apparatus if the type of the power supply apparatus is determined to be a first type and the power supply capability of the power supply apparatus is determined to be a second power supply capability higher than a first power supply capability that corresponds to the first type.

Electronic device and control method thereof

An electronic device includes a connector that includes a first terminal for receiving power from a power supply apparatus, a second terminal, a third terminal, and a fourth terminal; a control unit that controls power received from the power supply apparatus via the first terminal; and a determination unit that determines a power supply capability of the power supply apparatus by using the second terminal or the third terminal and the fourth terminal, wherein the determination unit determines the power supply capability of the power supply apparatus by using the third terminal and the fourth terminal before a predetermined transition occurs in the second terminal.

Electronic device that receives power from power supply apparatus and method thereof

An electronic device includes a connector that includes a first terminal for receiving power from a power supply apparatus, a second terminal, a third terminal, and a fourth terminal; a receiving power control unit that controls power received from the power supply apparatus via the first terminal; a determination unit that determines a power supply capability of the power supply apparatus by using the second terminal or the third terminal and the fourth terminal; and a control unit that restricts, before the power supply capability of the power supply apparatus is determined by using the third terminal and the fourth terminal, power to be received from the power supply apparatus via the first terminal when a predetermined transition occurs in the second terminal.
