Abstract: On a camera, the lens board (1) and the imager holder (10) are connected to one another through linear actuators (31). This allows the lens plane (EO) resp. the image plane (EB) to pivot around selectable axes lying accordingly in said planes. As a result, it affords the possibility with a camera and for a selected scene plane to easily comply with the Scheimpflug principle.

Abstract: A device in the form of a flat matrix of optoelectric transducer elements is mounted in a camera so that the flat matrix is perpendicular to an axis of an imaging beam in the camera and is movable in a pre-selected direction perpendicular to the imaging beam axis by a support apparatus which includes transfer levers that are tiltable about three swivel axes that are parallel and extend perpendicularly to the preselected direction.

Abstract: An optoelectric transducer arrangement (7b) is moved by being driven and by being controlled by means of cam/curve guides to convert the whole image to be imaged in a still camera despite that said transducer has a sensor surface that is smaller than the image area to be imaged in the image plane (B). The cam/curve arrangement includes four cam disks (15), for example, whereby one cam disk (15a) is driven by a motor. The transducer (7b) rides on a transducer carrier plate (21), which is moved by means of cams (19) on the cam disks (15, 15a). The transducer movement occurs thereby in a translatory manner.

Abstract: An electronic still camera includes an opto-electric transducer arrangement having a matrix of optical-to-electric converter elements for outputting parallel electrical signals providing a first electronic representation of an optical image received thereon from a lens, an electro-optical transducer arrangement (view screen) having a matrix of electrical-to-optical converter elements for converting a second electronic representation of an Image to an optical image, and a window-selecting unit for selecting a size and location of the second electronic representation within the first electronic representation,

Abstract: In a still photographic camera, the focal plane is determined by a matrix-like transducer arrangement (7) of optoelectronic sensor elements (9). The viewfinder image is directly generated by evaluation of the electric output signals (e.sub.9) from the transducerelements (9) that form the transducer arrangement (7).

Abstract: A sheet film cassette is provided with a flat housing 10 having a picture defining gate 14 on the front and a swingable rear wall 11 on the rear of the cassette. When the rear wall 11 is open, the cassette can be loaded from its rear. The rear wall 11 has a pressure device 20-22 located on its inner side to elastically force a sheet film loaded onto the cassette against supporting shoulders 18 located along the periphery of the picture defining gate 14 and lying in a common plane. The pressure device 20-22 has a flat pressure plate 20 and a bridge-like leader element 22 arranged between the pressure plate 20 and the rear wall 11. The leader element 22 has pairs of opposing support runners 23 that extend over the opposing peripheral edge of the pressure plate 20 and have stop faces 26 for interacting with the outermost peripheral edges of the loaded sheet film F.

Abstract: An apparatus permits, with the aid of an electronic calculator, the calculation of the spatial coordinates of object points of a motif scene to be photographed, and does so based upon the image points optically image inverted for the object points. The calculator is programmed so that, in accordance with Scheimpflug's Law, it generates output signals which correspond to an ideal setting of the film carrier and/or the lens carrier of the camera. By means of electro-optical and/or acoustical signal emitters, the ideal setting of the image and/or lens carriers, or the resetting required for the introduction of the ideal setting, are indicated to the photographer. For this purpose, the mechanical reset mechanisms for the film carrier and the lens carrier are connected to the actual-position signal emitters, which transmit actual-position signals to the calculator.

Abstract: A focusing-screen holder (13) provided with a focusing screen (14) is connected to a camera back (11) by means of springs (15). At least one cam plate (17) is located on the focusing-screen holder (13). This cam plate (17) can be swung between two end positions by means of an actuating handle (26) and cooperates with a slide face (22) of the camera back (11). In its first end position, cam plate (17) enables the focusing screen holder (13) to enter into abutting relation with the camera back (11) through the force of the springs (15). By swivelling the cam plate (17) to its second end position, the focusing-screen holder (13) is lifted off the camera back (11) against the force of the springs (15). The cam plate (17) has a radial cam (52) which is in abutting relation with an actuating pin (50). The latter is under the effect of a retarding mechanism (36) so that swivelling motions of the cam plate (17) from the second to the first end position are damped, dependent upon the actual velocity.

Abstract: A camera control device (21) with means for electrically controlling the shutter of a camera and for setting and displaying exposure time and aperture is electrically connected to an electronic exposure computer (22). The latter contains electronic circuitries for the logic operation of exposure parameters which shall be input and output in the form of coded digital signals. In a preferred embodiment, the relative aperture selected for each situation is read into the exposure computer (22) by means of a coder placed in the camera control device (21). The corresponding exposure time is calculated by the exposure computer (22) on the basis of the aperture and other exposure parameters and set automatically at the shutter. The exposure parameter reproducing the brightness of a subject to be photographed can be read into the exposure computer (22) either manually or, by connecting a photoelectric brightness sensor (23), automatically.

Abstract: A roll film (25) is guided behind a fixed light-path opening (22) in a housing 20 which limits the largest format of the pictures producible with the housing. Opposite areas of the light-path opening (22) may be covered up by two adjustable mask parts (51, 52) in order to change the picture window left open between the mask parts. Operating elements for the selection of the format of the picture window and its position within the light-path opening (22) are coupled with electro-mechanical transducers for producing electrical theoretical value signals. Electro-mechanical transducers (93, 94) for producing electrical actual-value signals are associated with the mask parts (51, 52). A reversible film travel apparatus (65-78) is connected with an electro-mechanical transducer (95) for producing electrical signals. All signals mentioned are fed to an electronic logical circuit module (130).

Abstract: An electrically controlled shutter device for a photograhic camera. The shutter device includes a shutter element which is mounted for movement for opening and closing a light admitting aperture of the camera. A drive mechanism causes the movement of the shutter element between its respective positions. An external trigger control provides for initiation of the opening and closing of the aperture during the exposure operation. A position monitoring mechanism is associated with the shutter element for providing a signal in dependence upon the shutter element being located in a predetermined position. A control mechanism is coupled to the output of the position monitoring mechanism and controls the operation of the shutter device as a function of the signal provided by the position monitoring mechanism and as a function of the signals from the external trigger control.

Abstract: A shutter device for a photographic camera has a pair of shutter blade members movable between first and second rest positions for opening or closing the camera aperture, including drive devices associated with the blade members for moving them in the same direction during an exposure sequentially and at a time interval, from the first to the second rest position. Additional drive devices associated with the shutter blade members are provided which, for a subsequent exposure, are capable of returning the blade members sequentially and at a time interval, in opposite direction, from the second to the first rest position.
