    摘要: An accessory apparatus is connectable to an imaging apparatus along with an interchangeable lens apparatus. The accessory apparatus includes an accessory communication unit configured to provide a communication channel to and from the imaging apparatus, an operation member allowing an operation by a user, and an accessory control unit configured to communicate with the imaging apparatus via the accessory communication unit. The accessory control unit notifies the imaging apparatus of a communication request according to detection of the operation of the operation member, and repeats transmitting operation state information indicating an operation state of the operation member to the imaging apparatus from when the communication request is notified to when an end of the operation is detected.

    摘要: The accessory apparatus provides, with an image-capturing apparatus, a notification channel used for providing a notice from the image-capturing apparatus to the accessory apparatus, a first data communication channel used for data transmission from the accessory apparatus to the image-capturing apparatus, and a second data communication channel used for data transmission from the image-capturing apparatus to the accessory apparatus. An accessory controller acquires from a timer, in response to receiving a transmission request as the notice, a first time of receiving the transmission request and acquires, in response to receiving a specific command through the second data communication channel from the image-capturing apparatus, accessory information corresponding to the first time or a second time acquired based on the first time. The accessory controller transmits the accessory information to the image-capturing apparatus through the first data communication channel.

    摘要: An imaging system has an interchangeable lens and a camera body capable of communicating with the interchangeable lens. A camera control unit of the camera body acquires focus-sensitivity-related information (including sensitivity information at an image height of the center and correction information of the sensitivity that changes depending on the image height) from a lens control unit of the interchangeable lens through communication at a suitable timing. The camera control unit corrects a change of the sensitivity caused by the image height using image height information of a focus detection region selected from a plurality of focus detection regions and the acquired focus sensitivity correction information. The camera control unit calculates a driving amount of the focus lens from the focus detection signal using the corrected focus sensitivity, generates a control signal for instructing the driving amount, and transmits the control signal to a lens control unit.

    摘要: An accessory apparatus, removably attached between an image capturing apparatus and an interchangeable lens, performs first communication with the image capturing apparatus and second communication with the interchangeable lens, and accepts a predetermined operation for operating a predetermined function that assists an autofocus (AF) operation. The accessory apparatus implements the predetermined function by controlling transmission of a control command to the interchangeable lens based on the predetermined operation and the control command for the AF operation accepted from the image capturing apparatus. To control the transmission of the control command, the accessory apparatus does not transmit a control amount included in the control command and pertaining to focus for the AF operation to the interchangeable lens, or changes the control amount and transmits the control amount changed to the interchangeable lens.

    摘要: A lens apparatus having a focus lens can be detachably attached to an imaging apparatus. A sensor of the imaging apparatus photoelectrically converts an optical image formed via the lens apparatus. A generation unit generates an image based on an image signal output from the imaging apparatus. The imaging apparatus receives information about a focal length variation from the lens apparatus received by a lens communication control unit configured to control communication with the lens apparatus, and an image magnification variation correction control unit corrects the magnification of the image based on the information.
