Abstract
An imaging apparatus to which a plurality of accessory apparatuses are attachable includes a camera communicator configured to provide a communication path with each of the plurality of accessory apparatuses, and a camera controller configured to communicate with the plurality of accessory apparatuses via the camera communicator. The camera controller transmits a first request to the plurality of accessory apparatuses, receives first information corresponding to whether or not to stop a communication with the imaging apparatus from each of the plurality of accessory apparatuses that have received the first request, and controls a communication with each of the plurality of accessory apparatuses according to the first information.
Claims28
An imaging apparatus to which a plurality of accessory apparatuses are attachable, the imaging apparatus comprising:
- a camera communicator configured to provide a communication path with each of the plurality of accessory apparatuses;
- and
- a camera controller configured to communicate with the plurality of accessory apparatuses via the camera communicator,
- wherein the camera controller transmits a first request to the plurality of accessory apparatuses, receives first information corresponding to whether or not to stop a communication with the imaging apparatus from each of the plurality of accessory apparatuses that have received the first request, and controls a communication with each of the plurality of accessory apparatuses according to the first information.
An accessory apparatus attachable to an imaging apparatus to which a plurality of accessory apparatuses are attachable, the accessory apparatus comprising:
- an accessory communicator configured to provide a communication path with the imaging apparatus;
- and
- an accessory controller configured to communicate with the imaging apparatus via the accessory communicator,
- wherein the accessory controller transmits to the imaging apparatus first information corresponding to whether to stop a communication with the imaging apparatus, in response to a first request received from the imaging apparatus.
An imaging system comprising:
- an imaging apparatus;
- and
- a plurality of accessory apparatuses attached to the imaging apparatus,
- wherein the imaging apparatus includes:

- and
- a camera controller configured to communicate with the plurality of accessory apparatuses via the camera communicator,
- wherein the camera controller transmits a first request to the plurality of accessory apparatuses,
- wherein each of the plurality of accessory apparatuses transmits first information corresponding to whether or not to stop a communication with the imaging apparatus in response to received first request, and
- wherein the camera controller controls a communication with each of the plurality of accessory apparatuses according to the first information.
A communication control method of an imaging apparatus to which a plurality of accessory apparatuses are attachable, the communication control method comprising the steps of:
- transmitting a first request to the plurality of accessory apparatuses;
- receiving, from each of the plurality of accessory apparatuses that have received the first request, first information corresponding to whether to stop a communication with the imaging apparatus;
- and
- controlling a communication with each of the plurality of accessory apparatuses according to the first information.
A communication control method of each of a plurality of accessory apparatuses attachable to an imaging apparatus, the communication control method comprising the steps of:
- receiving a first request from the imaging apparatus;
- and
- transmitting, to the imaging apparatus, first information corresponding to whether or not the accessory apparatus stops a communication, in response to the first request.
A non-transitory computer-readable storage medium storing a computer program for causing a computer of an imaging apparatus to which a plurality of accessory apparatuses are attachable, to execute a communication control method,
- wherein the communication control method includes the steps of:
- transmitting a first request to the plurality of accessory apparatuses;
- receiving, from each of the plurality of accessory apparatuses that have received the first request, first information corresponding to whether to stop a communication with the imaging apparatus;
- and
- controlling a communication with each of the plurality of accessory apparatuses according to the first information.
A non-transitory computer-readable storage medium storing a computer program for causing a computer of each of a plurality of accessory apparatuses attachable to an imaging apparatus, to execute a communication control method,
- receiving a first request from the imaging apparatus;
- and
- transmitting, to the imaging apparatus, first information corresponding to whether or not the accessory apparatus stops a communication, in response to the first request.
