Abstract
Provided is a technology enabling an imaging apparatus and an interchangeable lens to appropriately perform initialization processes. An interchangeable lens includes one or more lens-side processors configured to perform initialization of a plurality of lens-side elements. The one or more lens-side processors is further configured to transmit lens-side initialization element information indicating the plurality of lens-side elements to an imaging apparatus. The technology can be applied to, for example, a camera system including a detachable interchangeable lens and an imaging apparatus serving as a camera body side.
Claims19
An interchangeable lens, comprising:
- one or more lens-side processors configured to
- transmit first lens-side initialization element information indicating each common initialization element between a plurality of lens-side initialization elements and a plurality of body-side initialization elements on which an imaging apparatus confirms completion of initialization, and
- perform the initialization of the plurality of lens-side initialization elements, wherein
- the one or more lens-side processors is further configured to generate the first lens-side initialization element information based on an AND operation executed at the one or more lens-side processors, between (i) second lens-side initialization element information indicating the plurality of lens-side initialization elements and (ii) body-side initialization element information indicating the plurality of body-side initialization elements on which the imaging apparatus confirms completion of the initialization.
An interchangeable lens comprising:
- one or more lens-side processors configured to
- transmit lens-side initialization element information indicating a plurality of lens-side initialization elements on which the one or more lens-side processors performs initialization to an imaging apparatus;
- perform initialization of the plurality of lens-side initialization elements;
- and
- transmit an initialization completion signal for each common initialization element between the plurality of lens-side initialization elements and a plurality of body-side initialization elements on which the imaging apparatus confirms completion of the initialization, wherein
- when the plurality of lens-side initialization elements includes (i) a diaphragm and (ii) an exposure influencing element that influences an exposure adjustment process of the imaging apparatus and is not recognized by the imaging apparatus, the one or more lens-side processors is configured to transmit an initialization completion signal of the diaphragm after the initialization of the diaphragm and the exposure influencing element are completed.
