    摘要: A catadioptric light system such as a module lens system capable of being mounted on a camera is provided. A plurality of light reflecting and refracting optic members are designed to provide a desired image forming light path through the lens system. Disposed within the lens system is an electrochromic device that is responsive to an applied voltage to provide a predetermined degree of light transmission intensity through the lens system. The electrochromic device can be a thin film mounted on a transparent plate or on a reflective surface. The housing of the lens system can be advantageously designed to contain its own power source.

    摘要: An aperture stop control device for a zoom lens system includes a variable aperture stop, a first sensor for determining the diameter of the aperture stop and providing a first electrical signal representative of the diameter of the aperture stop means and a second sensor for generating a second electrical signal indicative of a designated F number. A signal generator provides a third electrical signal indicative of the focal length of the zoom lens system. A computing circuit computes an output electrical signal as a function of the second and third electrical signals to control the diameter of the aperture stop for automatically maintaining a designated F number during a zooming operation.

    摘要: An electrochromic light regulator for adjusting or regulating the amount of light passing therethrough comprises first, second and third electrode units stacked one above the other in spaced manner. A space between each adjacent two of the first to third transparent electrode units contains an electrochromic material and an ion conducting and electrically insulating layer. The second transparent electrode unit which is positioned intermediately between the first and third transparent electrode units serves as a counter electrode common to the first and third transparent electrode means.

    摘要: A camera has a zoom lens which includes a variator and a compensator. However, in order to simplify the whole external form of the camera, reduce the size thereof, and further to materially eliminate the treatment of appearance of the taking lens, a linear movement means which includes a threaded shaft provided for linearlly moving a variator and a compensator composing a zoom lens and the nuts to be engaged with the threaded shaft and an electrically driving means for driving this linear movement means are covered by a housing of a camera body, a zoom operation key provided on this housing is caused to be operationally related to an electric circuit which drives and controls the motor.
