    摘要： An automatic focus adjusting device detects focus condition respectively of a plurality of areas of a scene to be photographed to calculate respective focus adjusting data, and automatically adjusts the focus of an objective lens on an object in the scene based on the focus adjusting data. And the automatic focus adjusting device decides a focus adjusting data from the plurality of focus adjusting data based on an image magnification data representing the size of the object relative to the scene, a focal length of the objective lens or an object distance to automatically adjust the focus.

    摘要翻译： 自动对焦调整装置分别检测要拍摄的场景的多个区域的聚焦条件以计算各个焦点调整数据，并且基于焦点调整数据自动调整物体在场景中的对象上的焦点。 并且，所述自动聚焦调整装置基于表示所述物体相对于所述场景的尺寸的图像倍率数据，所述物镜的焦距或对象距离来决定来自所述多个焦点调整数据的焦点调整数据，以自动调整 焦点。
