相机系统、相机机身、更换镜头及通信方法
摘要：
本发明提供种能够在短时间内发送更多信息,且能够在适时发送进行动态图像的帧的图像处理时所需的信息的相机系统、相机机身、更换镜头及通信方法。本发明的相机系统由相机机身(200)和更换镜头(100)构成,其中,相机机身具备:机身侧通信部;及机身侧控制部,经由机身侧通信部将请求信号发送到更换镜头,且从更换镜头经由机身侧通信部接收与所发送的请求信号对应的回答信号,更换镜头具备:镜头侧通信部;及镜头侧控制部,经由镜头侧通信部接收到请求信号时,将与所接收的请求信号对应的回答信号经由镜头侧通信部发送到相机机身,镜头侧控制部至少在动态图像记录模式下不从相机机身接收镜头信息的请求信号,而与动态图像的帧同步发送镜头信息。
摘要（英）：

In a camera system including a camera body (200) and an interchangeable lens (100), the camera body includes a body-side communication unit, and a body-side control unit that transmits a request signal to the interchangeable lens via the body-side communication unit, and receives a response signal corresponding to the transmitted request signal from the interchangeable lens via the body-side communication unit, the interchangeable lens includes a lens-side communication unit, and a lens-side control unit that transmits the response signal corresponding to the received request signal to the camera body via the lens-side communication unit when receiving the request signal via the lens-side communication unit, and the lens-side control unit transmits lens information in synchronization with a frame of a video without receiving a request signal for lens information from the camera body at least in a video recording mode.
