摘要： In representing a depth of field in a camera, the depth of field is displayed on the basis of the magnitude of a field depth feeling Df which corresponds to human feeling. The field depth feeling Df is obtained by processing at least one of a depth of field on calculation, an object distance, a lens hypen-focal length, a diameter of permissible circle of confusion, a lens aperture value and a lens focal length.
摘要翻译：在相机中表示景深时，基于对应于人的感觉的场深度感觉Df的大小来显示景深。通过对计算的景深，物距，透镜缩焦长度，容许允许圆的直径，透镜孔径值和透镜焦距中的至少一个进行处理，获得场深度感Df。

摘要： A camera system in which a balancer is installed on one side of the camera and is linked to the camera body by two arms so that the photographer's hand can be inserted through a space defined by the camera body, the balancer and the arms. The balancer has substantial weight so as to balance the camera during hand held operation. Batteries are installed in the balancer and a flash unit may be incoporated therein. The arms may be rigid or may be a flexible belt. The balancer is preferably spaced from the camera body by an adjustable distance. Electrical contact is provided between the balancer and the camera body through the arms.
摘要翻译：一种照相机系统，其中平衡器安装在相机的一侧并且通过两个臂连接到相机主体，使得摄影者的手可以被插入通过由相机机身，平衡器和手臂限定的空间。平衡器具有相当的重量，以便在手持操作期间平衡相机。电池安装在平衡器中，闪光单元可能在其中被插入。臂可以是刚性的或可以是柔性带。平衡器优选地与相机主体间隔可调距离。通过手臂在平衡器和照相机主体之间提供电接触。

摘要： In representing a depth of field in a camera, the depth of field is displayed on the basis of the magnitude of a field depth feeling Df, which corresponds to human feeling and sensitivity. The field depth feeling Df is obtained by processing at least one of a calculated depth of field, an object distance, a lens hyper-focal length, a diameter of a permissible circle of confusion, a lens aperture value and a lens focal length.
摘要翻译：在相机中表示景深时，根据与人感觉和灵敏度对应的场深度感觉Df的大小来显示景深。通过处理计算出的景深，物距，镜头超焦距，容许允许圆的直径，透镜孔径值和透镜焦距中的至少一个来获得场深度感Df。
