Abstract:
(EN) Provided are a camera system, an interchangeable lens, a camera, and a camera system power supply method, with which it is possible to achieve a simpler configuration. A camera system (1) is provided with a camera (10) and an interchangeable lens (100). A plurality of lens driving powers (VL1 to VL3) having different voltages are supplied from the camera (10) to the interchangeable lens (100). The interchangeable lens (100) uses the plurality of supplied lens driving powers (VL1 to VL3) to drive a plurality of optical-member driving units, such as a focus driving unit and an aperture driving unit. Among the plurality of supplied lens driving powers (VL1 to VL3), the lens driving power (VL1) having the lowest voltage is used to generate the system power for operating a lens microcomputer (114).
(FR) L'invention concerne un système d'appareil de prise de vues, une lentille interchangeable, un appareil de prise de vues et un procédé d'alimentation électrique de système d'appareil de prise de vues, au moyen desquels il est possible d'obtenir une configuration plus simple. Un système d'appareil de prise de vues (1) est pourvu d'un appareil de prise de vues (10) et d'une lentille interchangeable (100). Une pluralité de puissances de commande de lentille (VL1 à VL3), ayant différentes tensions, sont fournies de l'appareil de prise de vues (10) à la lentille interchangeable (100). La lentille interchangeable (100) utilise la pluralité de puissances de commande de lentille fournies (VL1 à VL3) pour entraîner une pluralité d'unités d'entraînement d'élément optique, telles qu'une unité d'entraînement de mise au point et une unité d'entraînement d'ouverture. Parmi la pluralité de puissances de commande de lentille fournies (VL1 à VL3), la puissance de commande de lentille (VL1) ayant la tension la plus basse est utilisée pour générer la puissance de système permettant de faire fonctionner un micro-ordinateur de lentille (114).
(JA) 構成を簡素化できるカメラシステム、交換レンズ、カメラ、及び、カメラシステムの電源供給方法を提供する。カメラ(10)及び交換レンズ(100)を備えたカメラシステム(1)において、カメラ(10)から交換レンズ(100)に電圧の異なる複数のレンズ駆動用電源(VL1~VL3)を供給する。交換レンズ(100)は、供給された複数のレンズ駆動用電源(VL1~VL3)を使用して、フォーカス駆動部、絞り駆動部等を複数の光学部材駆動部を駆動する。また、供給された複数のレンズ駆動用電源(VL1~VL3)のうち最も低い電圧のレンズ駆動用電源(VL1)を使用して、レンズマイコン(114)を動作させるためのシステム電源を生成する。
