Abstract
A camera system includes a camera body, an interchangeable lens, and an accessory to be mounted between the camera body and the interchangeable lens, wherein the accessory includes a signal processing unit configured to process a signal input into the accessory, a storage unit configured to store information used for performing the signal processing, and a blocking unit configured to prevent direct communication from the camera body to the interchangeable lens when the information stored in the storage unit is rewritten via the camera body.
Claims17
A camera system comprising:
- a camera body;
- an interchangeable lens;
- and
- an accessory to be mounted between the camera body and the interchangeable lens,
- wherein the accessory includes a signal processing unit configured to process a signal input into the accessory, a storage unit configured to store information used for performing the signal processing, and a blocking unit configured to prevent direct communication from the camera body to the interchangeable lens when the information stored in the storage unit is rewritten via the camera body.
A camera system comprising:
- a camera body;
- an interchangeable lens;
- and
- an accessory to be mounted between the camera body and the interchangeable lens, wherein the accessory includes a signal processing unit configured to process a signal input into the accessory, and a storage unit configured to store information used for performing the signal processing,
- wherein the interchangeable lens includes a control unit configured to perform control to prevent the interchangeable lens from responding to a command transmitted from the camera body when the information stored in the storage unit is rewritten via the camera body.
A camera body capable of mounting an accessory which includes a signal processing unit configured to process an input signal and a storage unit configured to store information used for performing the signal processing, the camera body comprising:
- an output unit, wherein, when the information stored in the storage unit is rewritten via the camera body in a state in which the accessory is mounted on the camera body and an interchangeable lens is mounted on the accessory, the output unit outputs a command to prevent direct communication from the camera body to the interchangeable lens.
An accessory capable of being mounted between a camera body and an interchangeable lens, the accessory comprising:
- a signal processing unit configured to process an input signal;
- a storage unit configured to store information used for performing the signal processing;
- and
- a blocking unit configured to prevent direct communication from the camera body to the interchangeable lens when the information stored in the storage unit is rewritten via the camera body in a state in which the accessory is mounted on the camera body and the interchangeable lens.
An interchangeable lens capable of mounting an accessory which includes a signal processing unit configured to process an input signal and a storage unit configured to store information used for performing the signal processing, the interchangeable lens comprising:
- a control unit, wherein the control unit performs control to prevent a response to a command transmitted from the camera body when the information stored in the storage unit included in the accessory is rewritten via the camera body in a state in which the interchangeable lens is mounted to the camera body via the accessory.
A method for rewriting information stored in an accessory in a camera system including a camera body, an interchangeable lens, and the accessory mounted between the interchangeable lens and the camera body, the method comprising:
- blocking communication from the camera body to the interchangeable lens by the accessory;
- transmitting a command to rewrite the information stored in the accessory from the camera body to the accessory;
- and
- rewriting the information stored in the accessory after the command is received.
