    摘要: A lens-shutter coupling unit having a coupling structure of a lens shutter and a shutter unit capable of miniaturization and high-precision arrangement of a lens group, is provided. A shutter driving part for moving shutter blades and a filter driving part for moving an ND filter are disposed near an outer periphery of a protruding part of a lens group that protrudes from a barrel. The shutter driving part and the filter driving part can be disposed in a position (inner periphery) near an optical axis of the lens group. The center of rotation of the shutter blades and the ND filter can also be disposed near the optical axis of the lens group, and the shutter blades and the ND filter can be reduced in size. As a result, since the space at the time of retreat can be reduced, the shutter unit can be reduced in size.

    摘要: The invention relates to a method and a device for detecting the opening angle of the shutter (light or dark sector) of an adjustable rotating shutter (1) arranged in a film camera. Said shutter comprises a circular-segment-shaped or circular-sector shaped shutter wing (2) which is driven by a shutter motor via a shutter shaft (20), and also comprises an adjustable shutter adjustment wing (3) arranged in a coaxial manner in relation to the shutter wing (2) and which can be displaced in relation to said shutter wing by means of a shutter adjustment wing motor (33). According to the invention, the position of the shutter wing (2) and the position of the shutter adjustment wing (3) are detected during a rotation of the rotating shutter (1) and the difference between the two positions forms a value for the shutter opening angle or the light or dark sector of the rotating shutter (1).

    摘要: A shutter system for a movie camera or the like for controlling the film exposure including a main shutter wheel rotatably mounted on main drive shaft driven by a first motor and at least one adjustable shutter wheel positioned adjacent to and coaxially rotating with the main shutter wheel, the adjustable shutter wheel being mounted on a secondary shaft independently driven by a second motor. Both the aperture (determined by the relative positions of the shutter wheels of the main shutter wheel and adjustable shutter wheel) and the shutter speed are set by a controller which regulates the speed of each of the motors.

    摘要: A compact video camera which is operable at variable shutter speeds to capture high speed events which may be recorded and played back in slow motion for scene analysis. The video camera includes an image sensor, a variable diaphragm and a variable speed shutter. The variable diaphragm and variable speed shutter are controlled automatically to maintain constant the peak to peak signal level of the video signal produced by the image sensor so that the highest shutter speed is always maintained as scene brightness changes.

    摘要: A rotary shutter adapted to be used in an electronic still camera comprises a rotatable shutter having shutter openings which are variable in size. The shutter is rotated by an electric motor in order to open and close intermittently an exposure aperture of the camera. A phase detector for detecting the phase of rotation of the shutter member provides a series of phase signal, and cooperates with a signal generator for generating stop signals in synchronism with the phase signals when a particular shutter speed is selected and a circuit for braking the motor to stop the shutter member. Responsive to the particular shutter speed selecting operation, the shutter opening is opened to its maximum size and the rotary shutter is simultaneously stopped quickly in position so as to open fully the exposure aperture of the camera.

    摘要: In the disclosed motion picture system a shutter drive control circuit renders it possible to operate a rotary shutter in various exposure control modes including a mode in which rotation of the shutter is stopped for each long exposure of motion picture frame, the system can defer release of the shutter to the exposure aperture closed position pending completion of a picture frame exposure in any of the modes. The system terminates the preceding manual actuation of a shutter trigger when the taking of the particular picture frame is in progress.
