An image capturing apparatus that can be worn by a user as a result of being hung around a neck of the user includes an image capturing circuit, a first microphone that obtains an environmental sound, at least two second microphones that are intended to obtain a voice of the user and are arranged at a first distance from each other, a detection unit configured to detect a direction of a face of the user; and a sound processing unit that, with use of sound signals from the at least two second microphones, generates a directional sound signal that has directionality corresponding to the direction of the face of the user detected by the detection unit.

Image capturing apparatus

An image pickup apparatus to which an accessory is attachable includes a control unit communicable with the accessory, and configured to store information on power suppliable to the accessory and to acquire from the accessory at least one of information on the power required by the accessory, information on a power source for the accessory, and information on charge control of a battery provided in the accessory.

Image pickup apparatus, accessory, control method of image pickup apparatus, control method of accessory, and storage medium

A power supply apparatus includes a communication unit and a control unit. The control unit controls the communication unit so as to perform authentication communication with a cable after the cable is connected to the power supply apparatus, and controls the communication unit so as not to accept a request from an external apparatus connected to the cable in a period until the authentication communication is completed.

Power supply apparatus and control method

An electronic apparatus attachable to an accessory includes a power supply unit, and a control unit for controlling the power supply unit. The electronic apparatus can transition from a normal operating state to a power-saving state that includes a first power-saving state in which a power supply switch of the electronic apparatus is turned off, and a second power-saving state in which a non-operating state continues for a predetermined time. The control unit receives first information indicating whether or not the power supply from the electronic apparatus to the accessory is requested in the first power-saving state, and second information indicating whether or not the power supply from the electronic apparatus to the accessory is requested in the second power-saving state. The control unit causes the power supply unit to supply the power in the power-saving state where the power supply is requested.

Electronic apparatus and its control method, and accessory and its control method

An image capture apparatus comprises a first load, a second load and a power receiving circuitry that receives power from a second power supply which is different from a first power supply, and performs control so as to supply power from the first power supply to the first load and the second load, and controls such that when the power receiving circuitry is capable of receiving power that is greater than the power from the first power supply from the second power supply, the power from the first power supply is supplied to the first load, and the power from the second power supply which is greater than the power from the first power supply is supplied to the second load.

Image capture apparatus and control method

An electronic device includes a first voltage conversion unit, a second voltage conversion unit, and a control unit. The first voltage conversion unit generates a first voltage from power supplied from a first power supply or a second power supply. The second voltage conversion unit generates a second voltage, which is lower than the first voltage, from power supplied from the first power supply or the second power supply. The control unit controls a process of supplying power, supplied from the first power supply, to the first voltage conversion unit and a process of supplying power, supplied from the second power supply, to the second voltage conversion unit, in a case where a predetermined condition is satisfied.

Electronic device and control method

An electronic device comprises an interface including a first terminal that receives power from an external device and a second terminal for communicating with the external device, and at least one processor and/or at least one circuit to perform the operations of a communication unit that communicates with the external device via the second terminal, and a control unit that controls a connection between the second terminal and a ground, wherein in a case that a state of power received via the first terminal is a predetermined state, the communication unit sends a reset request for stopping the supply of power to the external device, and the control unit controls the connection between the second terminal and the ground from a connected state to a disconnected state.
