摘要: An auto-bracketing system for use with a camera. A plurality of exposure values, representing different exposure conditions, are calculated. The plurality of exposure values are calculated in accordance with at least two brightness values metered by optical sensors associated with the camera. A plurality of film frames, of a film installed in the camera, are subsequently exposed to the different exposure conditions.

摘要: A multi-area brightness measuring apparatus for a camera, which measures the brightness of an object in a center area of a photographing area and a circumferential area surrounding the center area to detect whether the object in the center area is in follow light state or in back light state in order to correct the exposure value. The exposure also can be controlled in accordance with the magnification, i.e. in accordance with the surface area of a main object occupying the center area.

摘要: The present invention relates to an optical camera having a zoom function in which a focal length can be varied or the variation is actuated by a focal length changing member, and in particular to a camera in which a focal length is varied through a motor. The optical camera has a zoom lens operable by a rotatable zoom ring for changing the focal length thereof. An automatic focusing operation is effected by a control means when the focal length is changed so that an image of an object viewed through a viewfinder remains in focus. The zoom lens can include a motor and an in-exposure zoom control means can be provided for controlling zooming movement of the lens during an exposure operation.
