Abstract
(EN) Provided are a camera system, a camera, an interchangeable lens, and a method for determining camera system compatibility, with which it is possible to easily and quickly determine compatibility between a camera and an interchangeable lens. An 11th terminal (CC11) provided to a camera (10) and an 11th terminal (LC11) provided to an interchangeable lens (100) are constituted by terminals capable of open drain output. The camera-side 11th terminal (CC11) is set to a first polarity if the camera (10) corresponds to a specific function, and is set to a second polarity if the camera (10) does not correspond. The interchangeable-lens-side 11th terminal (LC11) is set to the first polarity if the interchangeable lens (100) corresponds to a specific function, and is set to the second polarity if the interchangeable lens (100) does not correspond. The mutually connected camera-side 11th terminal (CC11) and interchangeable-lens-side 11th terminal (LC11) are the first polarity only if both are set to the first polarity. Accordingly, by detecting the polarity of the camera-side 11th terminal (CC11) and the polarity of the interchangeable-lens-side 11th terminal (LC11), both the camera (10) and the interchangeable lens (100) can determine whether there is compatibility.
(FR) L'invention concerne un système de caméra, une caméra, une lentille interchangeable et un procédé de détermination de la compatibilité du système de caméra, au moyen desquels il est possible de déterminer facilement et rapidement une compatibilité entre une caméra et une lentille interchangeable. Un 11ème terminal (CC11) fourni à une caméra (10) et un 11ème terminal (LC11) fourni à une lentille interchangeable (100) sont constituées par des terminaux pouvant prendre en charge une sortie de drain ouvert. Le 11ème terminal côté caméra (CC11) est réglé à une première polarité si la caméra (10) correspond à une fonction particulière, et est réglé à une seconde polarité si la caméra (10) ne correspond pas. Le 11ème terminal côté lentille interchangeable (LC11) est réglé à la première polarité si la lentille interchangeable (100) correspond à une fonction particulière, et est réglé à la seconde polarité si la lentille interchangeable (100) ne correspond pas. Le 11ème terminal côté caméra (CC11) et le 11ème terminal côté lentille interchangeable (LC11) connectés l'un à l'autre sont de la première polarité uniquement si les deux sont réglés à la première polarité. Par conséquent, par la détection de la polarité du 11ème terminal côté caméra (CC11) et de la polarité du 11ème terminal côté lentille interchangeable (LC11), la caméra (10) et la lentille interchangeable (100) peuvent déterminer s'il existe une compatibilité.
(JA) 簡単かつ迅速にカメラと交換レンズとの間の互換性を判定できるカメラシステム、カメラ、交換レンズ、及び、カメラシステムの互換性判定方法を提供する。カメラ(10)に備えられた第11の端子(CC11)及び交換レンズ(100)に備えられた第11の端子(LC11)をオープンドレイン出力が可能な端子で構成する。カメラ側の第11の端子(CC11)は、カメラ(10)が、特定の機能に対応している場合、第1極性に設定され、対応していない場合、第2極性に設定される。交換レンズ側の第11の端子(LC11)は、交換レンズ(100)が、特定の機能に対応している場合、第1極性に設定され、対応していない場合、第2極性に設定される。互いに接続されたカメラ側の第11の端子(CC11)及び交換レンズ側の第11の端子(LC11)は、互いが第1極性の場合にのみ第1極性となる。したがって、カメラ側の第11の端子(CC11)の極性及び交換レンズ側の第11の端子(LC11)の極性を検出すれば、カメラ(10)及び交換レンズ(100)の双方で互換性の有無を判定できる。
