摘要： A photographic apparatus of the foldable type in which, when in preparation for photography, a front housing carrying a photographic objective lens system together with a focusing mechanism therefor is moved away from a rear housing to form an exposure chamber for a sensitive material loaded in the rear housing. When the apparatus is rearranged to a folded position, the front housing is brought into compact relation with the rear housing. Since a distance-measurng device is located in the rear housing, there is provided an electrical channel for establishing electrically operative connection between the focusing mechanism and the distance measuring device as arranged along a path between the front and rear housing which remains substantially unchanged in length during the erecting and collapsing operation of the apparatus.

摘要： This invention relates to a device for focus detection or distance detection in which one or more images of a target formed by an optical system are received by photoelectric light receiving means to obtain a photoelectric output regarding the imaging condition of the image of the target and this photoelectric output is electrically processed through a processing circuit to thereby provide an electrical output representing the focus adjusted condition of the optical system with respect to the target or the distance to the target. According to the improvements of the present invention, such device is provided with projector means for illuminating a limited part of the detection view field determined by the focal length of the optical system and the dimensions of the effective light receiving surface of the photoelectric light receiving means, detection means for detecting whether or not the signal put out by the photoelectric light receiving means regarding the imaging condition of one or more images of the target is a sufficiently proper signal to ensure accurate focus detection or distance detection by the processing circuit, and control means for controlling the projector means in accordance with the detection output from the detection means. When proper detection is not ensured during the focus detection or the distance detection, the projector means is driven by the control means in accordance with the detection output of the detection means and the projection image of the projected light formed thereby on the target is utilized to effect focus detection or distance detection.

摘要： An automatic focusing device for an automatic focusing camera of the double image coincidence focusing type. A coupling mechanism causes an focus detecting movable mirror perform scanning motion according as the stroke of shutter releasing operation. Interlocking with the push-down of the shutter release button, focus detecting motion is performed while the distance from the focal plane to the photographing objective is indicated and/or memorized.During the first half of shutter releasing operation, focus detection and indication and/or memorization of the distance from the focal plane to the photographing objective are performed by the scanning motion of the movable mirror, and during the latter half of the shutter releasing operation, the indication and/or the lense focusing mechanism are controlled by a signal motion corresponding to the memorized value.The memorized value is scanned interlocked with the movement of a timing member released by shutter releasing operation or a focusing member and a lense displacement regulating mechanism is controlled by a signal motion corresponding to the memorized value.

摘要： A camera employing an automatic focusing system has a movable objective lens which is automatically moved to a properly focused position in accordance with a distance signal indicative of the distance between the camera and a target object to be photographed from a distance measuring element. The automatic focusing system further includes a discriminator which discriminates whether the distance measuring element properly produces the distance signal or fails to produce such distance signal. When the discriminator detects that the distance measuring element fails to produce the distance signal, the movable objective lens is automatically moved to a pan-focal position.

摘要： Disclosed is an improvement in an automatic focusing system for use with an optical instrument having a focusable objective which is adjustable in response to optical and electronic components of the system for determining object distance of a remote subject by comparing images of scanning and reference optical systems. The scanner of the optical system is driven oscillatably across an angle to detect a subject between infinity and the minimum focus condition of the objective lens. The scanner is adjustable in response to the focus condition of the lens for alignment of the angle scanned with the subject when the lens is in perfect focus by means of an electronic and mechanical interconnecting feedback between the lens focusing ring and the aiming device for the scanning system.The present invention relates to improvements in an automatic focusing system's for use with an optical instrument having a focusable objective. More particularly, the improvement relates to controlling the focusing system sensitivity in accordance with the various camera conditions which define depth of field e.g. object luminance, film sensitivity, shutter speed, focal length and the like.

摘要： A method and apparatus are provided which automatically focus a television camera or motion picture camera, or the like, in applications where, for any given camera-pointing direction, the desired subject will lie at a single-valued and predetermined distance from the camera such as on a planar surface. In one embodiment, a mechanical linkage enables a camera, shooting downward onto a flat playing field, to self-focus on any point in that field. In an electronic embodiment, a learn mode is included that handles events on more complicated terrains such as mountainous terrain in skiing events. In these cases, the self-focusing action is instantaneous, continuous and accurate.

摘要： A focusing system in a camera having an automatic focus detector to detect a focusing condition of a photo-taking optical system, an electromagnetic driving motor which is actuated in one direction, being controlled by the detector and having its operation stopped when an in focus state is detected by the detector, a movable member which can restrict the operation of said driving motor and at the same time is shiftable in response to the shifting of the photo-taking optical system, and an indicator which indicates the in focus position and is driven by said driving motor. The photo-taking optical system is shifted from a prescribed position in a predetermined direction for adjusting the focus. The movable member is correspondingly shifted from a prescribed position in a predetermined direction to release the restriction over the driving motor and to line up with the position of the indicator manually setting the optical system to the in focus position indicated by the indicator.
