Abstract: A power control unit of an electronic device executes auto power-OFF that causes the electronic device to automatically switch from a first operation mode to a second operation mode. A setting unit sets a set period. In a case where the auto power-OFF is executed when a period equal to or shorter than a first period is set as the set period, a status control unit performs control so that a first operation status at the time of the execution of the auto power-OFF is taken over when the electronic device is placed in the first operation mode next. In a case where the auto power-OFF is executed when a period longer than the first period is set as the set period, the status control unit performs control so that the first operation status is not taken over.

Abstract: An imaging device includes an imaging unit, a control unit that controls an imaging process that uses the imaging unit, a communication unit that communicates with an external device, and a communication control unit that, upon receipt of a press state of an image capture command button on the external device, provides the control unit with the press state. If the image capture command button is indicated as being pressed, the communication control unit provides the control unit with the press state in response to receipt of the press state. If the image capture command button is indicated as being not pressed, the communication control unit provides the control unit with the press state after a predetermined time period elapses.

Abstract: An illumination apparatus that emits light from a light source using accumulated electric energy and that performs wireless communication with another illumination apparatus via a communication unit includes a capacitor that accumulates the electric energy used to emit light from the light source, a detection unit that detects a charge state of the capacitor, and a notification unit that performs notification indicating information indicating that the illumination apparatus is in a flash available state and notification indicating information indicating that both the illumination apparatus and the other illumination apparatus are in a flash available state in a distinguishable manner in accordance with information on the other illumination apparatus received by the communication unit and a result of the detection performed by the detection unit.

Abstract: A communication device capable of preventing a failure in light emission control caused due to communication with a lighting device such as the master and the slave. The communication device is capable of connecting to an image pickup device and transmits a lighting instruction from the image pickup device to a lighting device through a communication unit capable of performing bidirectional communication. It is determined whether or not the lighting device is ready for lighting. The lighting device is prevented from transmitting information to the communication unit when the lighting device is ready for lighting.
