    摘要： A camera, equipped with a viewfinder having an optical axis different from the optical axis of the photographic lens system, has a parallax compensation apparatus for compensating for the parallax between the viewfinder and the photographic lens system. The parallax compensation apparatus includes a distance measuring device which measures an object's distance from the camera and an optical axis moving device which moves the optical axis of the photographic lens system according to the parallax, which is based on the results received from the distance measuring device, thereby matching the photographic image plane with the viewfinder field. In addition, the optical axis moving device moves the optical axis of the photographic lens system to compensate for hand trembling or other motion of the camera during shooting.

    摘要： A blur prevention device is equipped with first and second drive units which can move a blur prevention lens in a plane orthogonal to an optical axis of a main optical system. First and second transfer units transfer the amount of movement of the drive units to the blur prevention lens and first and second transfer receiving units receive the amount of movement in the respective directions from the respective transfer units. Each of the transfer receiving units can move relative to the one transfer unit other than the respective transfer unit. The blur prevention device has a specified direction for one of the transfer units and allows a degree of freedom outside the movement in the specified direction to the other transfer unit. Restriction gears, which are part of the drive units, restrict the amount of movement of the blur prevention lens in the plane orthogonal to the optical axis. And, by integrating a lens shutter or aperture with the blur prevention device, the blur prevention lens may be easily positioned in a central position of its drive range.

    摘要： A camera having an optical system which is shiftable to compensate for vibrations affecting the camera, a shift mechanism which shifts the optical system along an axis, and an urging mechanism. The urging mechanism provides an urging force along the axis to urge the optical system and to assist the shift mechanism in shifting the optical system. The urging force of the urging mechanism is approximately 1.5 to 5 times the weight of the optical system. Moreover, a feed screw mechanism includes a male portion and a female portion which cooperate, via a helical groove, to shift the optical system. The feed screw mechanism has an angle of friction and the helical groove has a lead angle that is smaller than the angle of friction.

    摘要： In a device, an angular velocity detector detects the angular velocity of a camera body and produces a signal conforming thereto. Whether the camera is performing pan shot is discriminated on the basis of the produced signal. Preferably, the discrimination is effected on the basis of a signal from which the high frequency component of the signal has been eliminated. Also, in one mode, the device sets an appropriate shutter speed when it is detected that the mode is pan shot.
