Title
(EN) CAMERA SYSTEM, CAMERA, INTERCHANGEABLE LENS, AND METHOD FOR DETERMINING CAMERA SYSTEM COMPATIBILITY
(ZH) 相机系统、相机、可换镜头及相机系统的兼容性判定方法
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 ofopen 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 setto 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) andthe interchangeable lens (100) can determine whether there is compatibility.
(ZH) 本发明提供一种能够简单且迅速地判定相机与可换镜头之间的兼容性的相机系统、相机、可换镜头及相机系统的兼容性判定方法。将设置于相机(10)的第11端子(CC11)及设置于可换镜头(100)的第11端子(LC11)由能够开路漏极输出的端子来构成。关于相机侧的第11端子(CC11),当相机(10)与特定功能对应时,设定为第1极性,当不与特定功能对应时,设定为第2极性。关于可换镜头侧的第11端子(LC11),当可换镜头(100)与特定功能对应时,设定为第1极性,当不与特定功能对应时,设定为第2极性。彼此连接的相机侧的第11端子(CC11)及可换镜头侧的第11端子(LC11)仅在彼此均为第1极性时成为第1极性。因此,只要检测相机侧的第11端子(CC11)的极性及可换镜头侧的第11端子(LC11)的极性,则能够在相机(10)及可换镜头(100)这两者中判定兼容性的有无。
