Claim Text:
1. A light emitting system in which a light emission control apparatus, that is communicable with an image capture apparatus, and transmits a light emission command to at least one other light emitting apparatus, wirelessly communicates with at least one controlled light emitting apparatus that emits light in response to a light emission command from another apparatus, the controlled light emitting apparatus comprising: a first transmission unit which wirelessly transmits predetermined state information about a predetermined state of the controlled light emitting apparatus itself to the light emission control apparatus; and the light emission control apparatus comprising: a receiving unit which receives the predetermined state information from the controlled light emitting apparatus, an informing unit which informs the image capture apparatus that a predetermined operation is complete, a second transmission unit which transmits, to the controlled light emitting apparatus, a signal to stop transmitting the predetermined state information, and a third transmission unit which transmits a light emission command to the controlled light emitting apparatus in response to an instruction from the image capture apparatus, a fourth transmission unit which transmits, to the controlled light emitting apparatus, an instruction to start transmitting the predetermined state information, and a detection unit which detects a change in number of controlled light emitting apparatuses that are communicating with the light emission control apparatus, wherein if the receiving unit receives, from all controlled light emitting apparatuses, the predetermined state information indicating that a predetermined operation is complete, the informing unit informs that the predetermined operation is complete, and the second transmission unit transmits the signal to stop transmitting the predetermined state information, and wherein upon detecting the change in number of controlled light emitting apparatuses by the detection unit after the second transmission unit transmits the signal, the fourth transmission unit transmits, to the controlled light emitting apparatuses, the instruction to restart transmitting the predetermined state information.
