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： A shutter device for a camera with an adjustable aperture comprises a connecting member for connection to a camera lens, the connecting member disposed along an optical axis; an image aperture disposed along an extension of the optical axis; and a reflective shutter and a shutter which are configured to cover the image aperture at least over a pre-settable period of time on a connection side of the image aperture facing the connecting member. The reflective shutter is disposed rotatably via a reflective shutter shaft, and the reflective shutter shaft is disposed perpendicularly to a plane of a reflective surface of the reflective shutter. The shutter is rotatably disposed via a shutter shaft, such that a combined shutter region results from projection in a direction of the optical axis to the image aperture, which is composed of a shutter region of the shutter and a shutter region of the reflective shutter.

The reflective shutter is disposed rotatably via a reflective shutter shaft, and the reflective shutter shaft is disposed perpendicularly to a plane of a reflective surface of the reflective shutter. The shutter is rotatably disposed via a shutter shaft, such that a combined shutter region results from projection in a direction of the optical axis to the image aperture, which is composed of a shutter region of the shutter and a shutter region of the reflective shutter. The shutter region of the reflective shutter by itself is at least as large as the shutter region of the shutter.

摘要： A rotary shutter for a motion picture camera consists of two sector blades which are rotatable about the same shaft. The angular relative position of one sector blade to the other is fixed to have a fixed open angle thereby when a smaller open angle is desired. When a larger open angle is desired, one sector blade is fixed in the camera at a position to open an exposure aperture and only other blade is rotated. One sector blade is selectively engaged with the other sector blade or fixed in the camera by axial movement thereof.

摘要： An electronic still camera includes a photographing optical system, an image pick-up device, and a transmission optical component. Light rays of an object which are passed through the photographing optical system are incident on the image pick-up device through the transmission optical component. The transmission optical component is shaped so as to shift an image point of an object image formed through the photographing optical system rearwards.

摘要： In the disclosed moving picture camera with an adjustable rotary shutter, the shutter has a rotary shutter and an adjusting blade. The shutter adjusting blade is adjustable coaxially to the rotary shutter, which adjusts a shutter aperture angle. A transmission and a positioning motor adjust the adjusting blade relative to the rotary shutter. A potentiometer is connected to the shutter adjusting blade and to the rotary shutter, for measuring the position of the shutter adjustment blade in relation to the rotary shutter. The potentiometer generates a position signal indicating the actual position of the shutter adjustment blade in relation to the rotary shutter.

摘要： A compact video camera which is operable at continuously 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 zoom lens, and a rotating shutter which is continuously adjustable to different shutter speeds. The camera components are dimensioned and configured in a compact design for easy-to-use hand-held operation. The shutter includes a pair of rotating shutter discs having openings which are selectively adjustable relative to each other to vary the interval during which the imager sensor is exposed to a scene projected onto it by the zoom lens. The shutter discs are mounted on respective first and second holow shafts. The first shaft is rotatably and slidably mounted on a portion of the second shaft by a linkage. Adjustment of the relative rotational position of the two disc to control the size of the relative shutter opening is effected by a cable which is connected at one end to the first shaft, which is passed through the hollow shafts and which is connected at its other end to a control member. The control member is actuated by a change in sensor signal intensity to effect a change in relative shutter opening.

The shutter includes a pair of rotating shutter discs having openings which are selectively adjustable relative to each other to vary the interval during which the imager sensor is exposed to a scene projected onto it by the zoom lens. The shutter discs are mounted on a pair of spaced, hollow shafts. Adjustment of the relative rotational position of the two discs to control the size of the relative shutter opening is effected by a push rod linked to and slidably mounted within the hollow shafts. Axial movement of the push rod in response to a change in sensor signal intensity varies the opening defined by the two shutters.

摘要： In the disclosed motion picture shutter angle control device, a motor serves exclusively for varying the shutter opening angle formed with a number of shutter blades. A detector detects when a predetermined shutter opening angle is obtained and delivers a signal which is used in a fade operation and the overlap operation to change the maximum opening angle.
