    • A shutter for a camera having leading and trailing blade groups movably interposed in between a plurality of plate-shaped members each of which having a shutter aperture, each of the blade groups including a plurality of divided blades, is provided with a protruding part which is formed along the edge of the shutter aperture in a slanting and outwardly protruding manner. This protruding part prevents the blade groups from being damaged by the impact of collision of them with the edge of the shutter aperture even when they travel in a state of being warped to the outside of a normal blade moving area by an external force.

    • In an electronic camera, during a photographing operation for photographing a white sheet of paper or the like to obtain white balance data, a plurality of distance measuring points provided in an automatic focusing mechanism are restricted to only the one that is located at a central portion of the image plane. Further, a determination level used for determining an in-focus state in the automatic focusing mechanism is set lower than where an ordinary object is photographed. Accordingly, the photographing operation for obtaining white balance data can be completed for a short time. Furthermore, if the automatic focusing operation itself is inhibited during the photographing operation for photographing a white sheet of paper or the like to obtain white balance data, that photographing operation can be completed for a very short time.
    • 在电子照相机中,在用于拍摄白纸等的摄影操作中获得白平衡数据时,设置在自动对焦机构中的多个距离测量点仅限于位于中央部分 的图像平面。 此外,将用于确定自动聚焦机构中的对焦状态的确定水平设置为低于拍摄普通物体的确定水平。 因此,用于获得白平衡数据的拍摄操作可以在短时间内完成。 此外,如果在用于拍摄白纸等的拍摄操作期间自动聚焦操作本身被禁止以获得白平衡数据,则该拍摄操作可以在非常短的时间内完成。
