Abstract: Motion-picture camera with a taking optics for projecting frames onto a motion-picture film, moved by means of a film transport mechanism along a film path. In addition, in the vicinity of the film path a frame-projection device (16) is located to project an additional frame (32) onto motion-picture film (3) and/or to superimpose a partial frame (36, 37) on frame (31) exposed or to be exposed by taking optics (15).

Abstract: An autofocusing motion picture camera having an adjustable focus zoom lens and having means for periodically determining the distance to subjects within the focusing range of said lens is provided with an object presence sensing transducer having an acceptance angle that encompasses the optical field of view angle of said lens whenever the telephoto lens position is selected.

Abstract: Automatic and rapid exposure control is incorporated in a camera having facilities for directing, along a common path, a pair of independent noncoincident light beams from an external object and from a separately illuminable item, such as a databearing transparency within the camera. A photoelectric circuit responsive to the total quantity of the directed light generates a proportional control voltage for operating an adjustable diaphragm to maintain a predetermined incident level of the directed light on the camera film and/or controlling the item illuminator or an auxiliary illuminator for the external object. Threshold controlled, motor-instrumented apparatus may be additionally provided to advance the film, to selectively operate a camera shutter, and to illuminate the item in response to trigger signals generated, e.g., upon the detection of the presence of the external object.
