摘要： The invention relates to a method for focussing the shooting lens (2) of a motion-picture or video camera on an object (T) whose position on a monitor is indicated by an indicating device whereby orienting a distance measuring device toward the object (T). The measured distance of the object (T) from the camera (1) is furnished to a control unit in the form of a set value for automatically focussing the shooting lens (2) and/or is indicated as a measured value for manually focussing the shooting lens (2). In order to eliminate resulting parallax errors from the distance of the distance measuring device from the optical axis of the motion-picture camera, the focus to be set on the shooting lens (2) is determined from a vector (A) pointing from the shooting plane (FE) of the camera to the measuring point (LRF) of the distance measuring device, from a vector (B) pointing from the shooting plane (FE) of the camera to the optical principal point (OHP) of the shooting lens (2), from a vector (C) pointing from the measuring point (LRF) of the distance measuring device to the object (T) to be focussed, and on data of the shooting lens (2).

摘要： The invention relates to a motion picture camera (1) having a film magazine (2) inside of which a film supply reel (31), from which a motion picture film (3) to be exposed having a supporting layer and a light-sensitive emulsion layer is unwound and moved over a film conveying path past a picture window (14) for picture exposure, and a film winding reel (32) are placed, onto which the exposed motion picture film (3) is wound. The invention provides that a device (6, 8, 9), which serves to remove foreign bodies located on one or both surfaces of the motion picture film (3), is placed in the film conveying path between the film supply reel (31) inside the film magazine (2) and the picture window (14).

摘要： A multiplexed motion picture camera comprising a sturdy plate (43) for supporting a plurality of camera mechanisms (28-31), each camera mechanism (28-31) provided with an adjustable support device, and connected to a common objective lens (1) through an arrangement of lenses (6), beam splitters (7, 10, 13), multiple axis relays (16-19), and additional shutter devices (20-23). Each camera mechanism (28-31) and its associated optical relays (16-19), shutters (20-23), and lenses can be individually controlled and adjusted to allow an operator a broad range of photographic settings to achieve a smooth, continuous, natural motion moving image recording.

摘要： Die Erfindung betrifft eine Laufbildkamera mit einem Kameraobjektiv 3, einem in der Filmbahn eines Laufbildfilmes angeordneten Bildfenster 7, an dem der Laufbildfilm mittels eines Filmtransportmechanismus 2 intermittierend vorbeibewegt wird, bei dessen Stillstand eine zwischen dem Kameraobjektiv 3 und dem Bildfenster 7 angeordnete Blende 5 geöffnet wird. Im Strahlengang hinter dem Kameraobjektiv 3 ist zusätzlich eine Verschlußblende 8 angeordnet, die eine lichtdichte Abdeckung des Laufbildfilms bei Einzelbildbelichtung bzw. Langzeitaufnahmen bewirkt.

摘要： In a first guide unit (53) a plurality of electrodes are provided facing the edge of a movie film (1) containing a plurality of perforations (3A, 3B) formed along the longitudinal direction of the movie film (1), in a second guide unit a band shaped conducting material (24) is provided facing the electrodes having the movie film (1) between, and each stop position with respect to window holes is detected based on the amount of change of each electrostatic capacity changing depending on the displacement rate from each stop position of a plurality of condensers which are formed making each electrode and conducting material as a pole plate respectively and making the thickness of the movie film as the distance of pole plates. Therefore, a film position detection device, a film image display device and a movie film recording device capable of further improving the movie film position detection accuracy can be realized with the simple construction.

摘要： Device (16) for controlling and regulating the illumination and feed speed of a motion picture film in a motion picture camera whose film feed motor (26) is connected to a rotational speed controller (23) and has a rotary shutter which is connected to a position indicator in form of a potentiometer (6) and which can be adjusted by means of an adjusting motor (3). A reference value of the diaphragm aperture (light sector) of the adjustable rotary shutter which depends on the instantaneous film feed speed is transmitted by the controlling and regulating device (16) via a transducer (14) to a position controller (13). The product of the film feed speed and the diaphragm aperture is a constant. Different film feed speeds, diaphragm apertures and transit times can be input into the camera in a programming device (19) or in a remote control device (181, 182) and released sequentially by means of a program key (183).
