Abstract
A camera microcomputer receives first accessory attribute information of the accessory attribute information through the third communication channel by using a first communication method and then switches from the first communication method to a second communication method different from the first communication method, and controls communication so as to receive second accessory attribute information of the accessory attribute information through the third communication channel by using the second communication method.
Claims18
An image capturing apparatus to which an accessory apparatus is attachable, the image capturing apparatus comprising:
- a communication control section implemented by at least one processor and configured to control communication with the accessory apparatus by a first communication method or a second communication method, and to control reception of accessory attribute information,
- wherein the second communication method is capable of performing communication at a speed that is higher than a speed at which the first communication method is capable of performing communication,
- wherein the accessory attribute information includes information indicating function that can be performed by the accessory apparatus,
- wherein the communication control section is configured to control communication to receive first accessory attribute information of the accessory attribute information by using the first communication method, then to switch from the first communication method to the second communication method, and to control communication to receive second accessory attribute information of the accessory attribute information by using the second communication method, and
- wherein the second accessory attribute information contains predetermined information indicating function that can be performed by the second communication method which is not included in the first accessory attribute information.
An accessory apparatus to which an image capturing apparatus is attachable, the accessory apparatus comprising:
- a communication control section implemented by at least one processor and configured to control communication with the image capturing apparatus by a first communication method or a second communication method, and to control transmission of accessory attribute information,
- wherein the second communication method is capable of performing communication at a speed that is higher than a speed at which the first communication method is capable of performing communication,
- wherein the accessory attribute information includes information indicating function that can be performed by the accessory apparatus,
- wherein the communication control section is configured to control communication to transmit first accessory attribute information of the accessory attribute information by using the first communication method, then to switch from the first communication method to the second communication method, and to control communication to transmit second accessory attribute information of the accessory attribute information by using the second communication method, and
- wherein the second accessory attribute information contains predetermined information indicating function that can be performed by the second communication method which is not included in the first accessory attribute information.
A control method for an image capturing apparatus to which an accessory apparatus is attachable, wherein the image capturing apparatus includes a communication control section implemented by at least one processor and configured to control communication with the accessory apparatus by a first communication method or a second communication method, and to control reception of accessory attribute information, wherein the second communication method is capable of performing communication at a speed that is higher than a speed at which the first communication method is capable of performing communication, and wherein the accessory attribute information includes information indicating function that can be performed by the accessory apparatus, the control method comprising:
- controlling, via the communication control section, communication to receive first accessory attribute information of the accessory attribute information by using the first communication method, then to switch from the first communication method to the second communication method, and to control communication to receive second accessory attribute information of the accessory attribute information by using the second communication method,
- wherein the second accessory attribute information contains predetermined information indicating function that can be performed by the second communication method which is not included in the first accessory attribute information.
A control method for an accessory apparatus to which an image capturing apparatus is attachable, wherein the accessory apparatus includes a communication control section implemented by at least one processor and configured to control communication with the image capturing apparatus by a first communication method or a second communication method, and to control transmission of accessory attribute information, wherein the second communication method is capable of performing communication at a speed that is higher than a speed at which the first communication method is capable of performing communication, and wherein the accessory attribute information includes information indicating function that can be performed by the accessory apparatus, the control method comprising:
- controlling, via the communication control section, communication to transmit first accessory attribute information of the accessory attribute information by using the first communication method, then to switch from the first communication method to the second communication method, and to control communication to transmit second accessory attribute information of the accessory attribute information by using the second communication method,
- wherein the second accessory attribute information contains predetermined information indicating function that can be performed by the second communication method which is not included in the first accessory attribute information.
