摄像设备及其控制方法和镜头单元及其控制方法
摘要：
本发明涉及一种摄像设备及其控制方法和镜头单元及其控制方法。所述摄像设备能够移除地安装有镜头单元，并且包括：摄像元件；第一焦点检测部件，用于基于从所述摄像元件输出的信号，进行利用对比度检测方法的焦点检测；第二焦点检测部件，用于基于从所述摄像元件输出的一对图像信号，进行利用相位差检测方法的焦点检测；以及控制部件，用于基于所述第一焦点检测部件或所述第二焦点检测部件所检测到的聚焦位置来进行聚焦控制，并且所述控制部件从所安装的镜头单元接收与利用所述相位差检测方法的聚焦位置的偏移有关的第一信息，并且根据所述第一信息来判断是否使用所述第二焦点检测部件来进行聚焦控制。
摘要（英）：

An image pickup apparatus on which a lens unit is to be removably mounted includes an image pickup element, a first focus detection unit which performs a focus detection by a contrast detection method based on a signal output from the image pickup element, a second focus detection unit which performs a focus detection by a phase difference detection method based on a pair of image signals output from the image pickup element, and a control unit which performs a focus control based on an in-focus position detected by the first or second focus detection unit, and the control unit receives, from the mounted lens unit, first information related to a displacement of the in-focus position by the phase difference detection method and determines whether to use the second focus detection unit for the focus control according to the first information.
