Abstract
An imaging apparatus to which an accessory apparatus is attachable includes a camera controller configured to communicate with the accessory apparatus. The camera controller receives first information on a data size receivable by the accessory apparatus, performs a setting for a data size to be transmitted to the accessory apparatus based on the first information, and communicate with the accessory apparatus based on the setting.
Claims39
An imaging apparatus to which an accessory apparatus is attachable, the imaging apparatus comprising a camera controller configured to communicate with the accessory apparatus,
- wherein the camera controller receives first information, and performs communication based on the first information, and
- wherein the camera controller requests the accessory apparatus for data having a data size equal to or less than a data size indicated by the first information.
An accessory apparatus attachable to an imaging apparatus, the accessory apparatus comprising an accessory controller configured to communicate with the imaging apparatus,
- wherein the accessory controller transmits first information, and performs communication based on the first information, and
- wherein the accessory apparatus receives, from the imaging apparatus, a request for data having a data size equal to or less than a data size indicated by the first information.
A communication control method of an imaging apparatus to which an accessory apparatus is communicatively attachable, the communication control method comprising the steps of:
- instructing the imaging apparatus to receive first information;
- instructing the imaging apparatus to perform communication based on the first information;
- and
- instructing the imaging apparatus to request the accessory apparatus for data having a data size equal to or less than a data size indicated by the first information.
A communication control method of an accessory apparatus communicatively attachable to an imaging apparatus, the communication control method comprising the steps of:
- instructing the accessory apparatus to transmit first information;
- instructing the accessory apparatus to perform communication based on the first information;
- instructing the accessory apparatus to receive, from the imaging apparatus, a request for data having a data size equal to or less than a data size indicated by the first information.
An imaging apparatus to which an accessory apparatus is attachable, the imaging apparatus comprising a camera controller configured to communicate with the accessory apparatus,
- wherein the camera controller receives second information, and performs communication based on the second information, and
- wherein the camera controller transmits data having a data size equal to or less than a data size indicated by the second information.
An accessory apparatus attachable to an imaging apparatus, the accessory apparatus comprising an accessory controller configured to communicate with the imaging apparatus,
- wherein the accessory controller transmits second information, and performs communication based on the second information, and
- wherein the accessory apparatus receives, from the imaging apparatus, a request for data having a data size equal to or less than a data size indicated by the second information.
A communication control method of an imaging apparatus to which an accessory apparatus is communicatively attachable, the communication control method comprising the steps of:
- receiving second information and performing communication based on the second information;
- and
- transmitting data having a data size equal to or less than a data size indicated by the second information.
A communication control method of an accessory apparatus communicatively attachable to an imaging apparatus, the communication control method comprising the steps of:
- transmitting second information and performing communication based on the second information;
- and
- receiving, from the imaging apparatus, a request for data having a data size equal to or less than a data size indicated by the second information.
