Provided are an auto focus (AF) locking unit and a photo-graphing apparatus including the AF locking unit. In particular, the AF locking unit supports a lens group barrel holder that is descended by a movement of a front barrel in an optical axis direction by using a locking lever provided with an elastic force, and the photographing apparatus includes the AF locking unit. According to an embodiment, the AF locking unit supports the lens group barrel holder including lenses in the optical axis direction by using a driving force transmitted from a motor in correspondence to movements of a cam barrel and a front barrel, and the photographing apparatus includes the AF locking unit.

A device and method for three-dimensional (3-D) imaging using a defocusing technique is disclosed. The device comprises a lens, a central aperture located along an optical axis for projecting an entire image of a target object, at least one defocusing aperture located off of the optical axis, a sensor operable for capturing electromagnetic radiation transmitted from an object through the lens and the central aperture and the at least one defocusing aperture, and a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object. Different optical filters can be used for the central aperture and the defocusing apertures respectively, whereby a background image produced by the central aperture can be easily distinguished from defocused images produced by the defocusing apertures.

A camera for automatically producing an identity card entirely photographically with writing and a picture of the person on the card, can selectively either photograph the actual person or a picture of the person, so that it is not necessary for the person to be present if that person can furnish a photograph. The camera feeds roll film to a first exposure station where borders are produced by exposure to saturation light, then to a second exposure station for photographing the writing and, optionally, the photograph of the person, then to a third exposure station for the optional photograph of the actual person. The second exposure station has a selectively operable mask for shielding part of the film from light if the third exposure station is to be used for photographing the actual person.
摘要:
An electrical-optical system for displaying background images, superimposing manually generated animated drawings electronically on such background images, and recording the composite double images on a movie film. The background images initially are reproduced optically or electronically in order to superimpose the animated drawings thereon in exact registration. The background images recorded on the movie film are made by direct optical projection to avoid distortion produced within the electronic system.
摘要:
A camera system which employs an objective lens-shutter element to form an image of a subject positioned exteriorly of the camera on a sheet of photographic material and an arrangement including another lens and a plurality of mirrors, one of which mirrors is pivotably mounted in the optical path between the first mentioned lens and the sheet of photographic material, for forming an image of a data card mounted interiorly of the camera on the same sheet of photographic material. An arrangement, including a polarizing plate adapted to overlie the sheet of photographic material, restricts the light rays intersecting a first area of such material to those from the subject and the light rays intersection a second area of such material to those from the data card. The section of the polarizing plate overlying the first such area has its transmission axis orthogonally aligned with that of the section of the polarizing plate adapted to overlie the second such area. This plate is mounted in the system so as to be replaceable with other such plates on which the separate polarized sections thereof differ in location and/or size. The aforementioned pivotably mounted mirror is adapted to be displaced out of such optical path to facilitate photographing the subject. Other features are included so that when a button is depressed by the operator, a rotating cam first effects the displacement of the polarizing plate against the sheet of photographic material, energizes a data card flash unit, rotates the mirror and finally activates the shutter associated with the subject optics.
摘要:
Method of and apparatus for making motion-picture and television films with simultaneous projection of a background on a screen, by using an intermediate reflection on a semisilvered mirror, which consists in providing means for producing a rectilinear or circular lateral movement of the camera in combination with the pivotal movement of the camera in a horizontal plane in order to preserve the coincidence of the projections of said camera and of the projector on said semisilvered mirror.
摘要:
A variable-volume enclosure that enables the photographing, from outside the enclosure, of highly reflective, objects placed in the enclosure without the reflections of things in the environment surrounding the enclosure being seen in the objects includes: (a) a translucent, planar base, (b) a pliable, two-way mirror that is configured so that, when its opposing edges are brought towards one another, the mirror's central portion bends upward to create a temporary enclosed region of the enclosure, (c) an attachment mechanism for fixedly attaching said one of the mirror's edges to the base's top surface, (d) an adjustable attachment mechanism that temporarily and adjustably attaches the mirror's other edge to the base's top surface, (e) a translucent covering which is adjustably attached to a mirror end.
