摘要： A method for determining the current camera aperture (working aperture) of lenses on digital cameras having a viewfinder eyepiece and internal exposure measurement through the lens is wherein a further external exposure measurement is carried out past the lens and the value of the working aperture is determined from a reference table stored in the digital camera from the difference ΔBV between the two measured exposure values BV(int) and BV(ext). A digital camera suitable for carrying out the method wherein outside the region covered by the lens tube, the housing of the digital camera has an additional window for a further exposure meter with an upstream optics that is directed onto the subject and serves to restrict the shooting angle, and includes a memory for a reference table for determining the aperture value.

摘要： An interchangeable lens connects in a prescribed position to a support surface on a camera of a camera system using a locking apparatus. A method and apparatus for identifying interchangeable lenses uses optical radiation. After the locking operation is performed, a defined optical radiation is directed from two or more, preferably six, light transmitters arranged in the support surface to reflecting or absorbing surfaces on the locking apparatus which are assigned to said light transmitters. The radiation returning from the respective reflecting/absorbing surfaces is picked up by light receivers arranged next to the light transmitters in the support surface. A binary coded signal for identifying the interchangeable lens is formed from the output signals of the light receivers.

摘要： A switchable flap valve having at least one valve plate (2, 2a, 2b) disposed for pivoting about a longitudinal axis in a housing part (1) for opening or closing a valve opening (11) provided in the housing part (1) in which a strip element (4, 4a, 4b) is formed on the upper side of the valve plate (2, 2a, 2b) aligned parallel to the longitudinal axis of the valve plate. The surface of the strip element (4, 4a) is inclined toward an adjacent housing wall (20) or toward a second strip (4b) and forms a hollow channel with the housing wall (20) or with the strip (4b). The free longitudinal edge (18) of the strip (4, 4a, 4b) is held in a latch mechanism (7, 8) to maintain the valve plate (2, 2a, 2b) in the closed position. In the housing part (1) at least one opening (13) communicating with one end of the hollow channel is provided, which also is in communication with a pressure generator (14) whose actuation introduces pressure into the hollow channel and elastically deforms the strip elements (4, 4a, 4b) to release the strip elements from the holders or latches (7, 8) so that the valve plate (2, 2a, 2b) can pivot to the open position.

摘要： A device for exposure metering in photographic cameras including a reflector located in the imaging beam path. The surface of the reflector is provided with a reflecting structure whose size corresponds at least approximately to that of the image recording format. At least one photoelectric receiver records the light intensity of a portion of the image reflected from the reflecting structure. The reflector is pivotally mounted in the camera housing such that during exposure metering the reflector surface is in the vicinity of the film plane of the camera. A limited portion of the reflector is transparent and a photoelectric receiver is set into the backside of the reflector behind the transparent portion.
