此專利提出者係Olympus Imaging Corp. (Tokyo, JP)
公佈日期為2010年5月4日
其中的「發明摘要」原文如下：

The present invention relates to detecting a focus of a lens unit by a method selected from a plurality of focus detection methods based on information on the lens unit taken into a digital camera from the lens unit, which is attached to the digital camera.

Next, one example of a structure of the present invention will be described. A digital camera to which a lens unit having a focus lens as a shooting optical system is detachably attached, comprising: an imaging section having an image pickup device to convert an optical image of a subject which has struck via the lens unit into an electrical signal; a first focus detecting section which detects focal information of the focus lens by a first focus detection method; a second focus detecting section which detects focal information of the focus lens by a second focus detection method; a control section which selects the focal information detected by at least one of the first focus detecting section and the second focus detecting section and which generates a focusing control signal to control a focal position of the focus lens based on the selected focal information; and a transmitting and receiving section which transmits the focusing control signal to the lens unit and which receives information on the lens unit transmitted from the lens unit, wherein the control section selects the focal information based on the information on the lens unit acquired via the transmitting and receiving section.

簡單翻譯了一下
因本篇詞句較為繁複
小弟非相關背景出身
翻譯也許有誤
還請大家不吝指教


本項發明係有關從多種鏡頭對焦偵測方法中判定鏡頭元件偵測到焦點的方法，這些方法係基於裝設在相機上之鏡頭傳達至相機的資訊而來的。

接下來，說明有關本發明的結構範例。一部將鏡頭元件作為拍攝光學系統的數位相機是可分開組成的，其可以包含：一個可以將實體光學影像擷取為電子信號的影像區域、一個透過首要對焦方法偵測鏡頭對焦資訊的首要對焦偵測區域、一個透過第二對焦方法偵測鏡頭對焦資訊的第二對焦偵測區域、一個能從首要及第二對焦偵測區域所提供的資訊中選擇對焦資訊並予以整合為對焦控制訊號及控制對焦定位的控制區域，以及一個控制區域可以從鏡頭元件自該區域取得的資訊中選擇對焦資訊，並傳送對焦控制信號至鏡頭及在鏡頭元件上接收從鏡頭元件而來的訊息的傳送及接收區域。

這種雙重同步對焦方法看起來應該不是針對M4/3而來的
所以也許Olympus還是有在研發4/3的東西？
