Stereo Camera
A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera (the intra-axial distance) is about the distance between one's eyes (known as the intra-ocular distance) and is about 6.35 cm, though a longer base line (greater inter-camera distance) produces more extreme 3-dimensionality. In the 1950s, stereo cameras gained some popularity with the Stereo Realist and similar cameras that employed 135 film to make stereo slides. 3D pictures following the theory behind stereo cameras can also be made more inexpensively by taking two pictures with the same camera, but moving the camera a few in ...

Nimslo
The Nimslo is a stereo camera with a brightfield viewfinder that produces 3D pictures that can be viewed without glasses. This is done using lenticular printing. It uses common 35 mm film in 135 film format cartridges. It was produced in the 1980s by Nimstec of Atlanta, and manufactured by Timex in Dundee, Scotland. Features The Nimslo had fixed focus and automatic exposure. It featured a leathered metal body and glass lenses. Using its four lenses, four images from slightly different viewing angles were taken simultaneously. With the individual images half the size of the usual 35mm image frames, each 3D photograph taken used the space of 2 full 35mm exposures on the film. So a roll labeled as "36 exposures" would yield 18 3D pictures with four images each. The Nimslo was the first consumer level three-dimensional lenticular camera of the 1980s. There were previous lenticular cameras aimed at amateurs, such as the six-lens Lentic, introduced in 1953, which used 120 roll ...

Sputnik Stereo Camera
Sputnik 1 (; see § Etymology) was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out, and continued in orbit for three months until aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word ''sputnik'' is Russian for ''satellite'' when ...

Kodak Stereo Camera
The Kodak Stereo Camera was a 35mm film stereo camera produced between 1954 and 1959. Similar to the Stereo Realist, the camera employed two lenses to take twin shots of scenes, which could then be viewed in dedicated image viewers. The lenses supported adjustable apertures and variable shutter speeds. The camera had a reputation for being easy to use, and sold approximately 100,000 units during the time it was produced. Description The Kodak Stereo Camera was a Realist Format camera released late in 1954. It used 35mm slide film to produce stereo pair images in the standard 5P Realist format. This allowed Kodak Stereo Camera owners to use most accessories and services originally designed for the Stereo Realist. It was the second best selling stereo camera of the 1950s era, eclipsed only by the Stereo Realist. Features Though it lacked a rangefinder the Kodak stereo camera is often considered to be easiest of the 50s stereo cameras to use. Unlike the Realist, the Kodak had ...

Leia (company)
Leia Inc. is an American company producing 3D Lightfield products and software applications. Leia is headquartered in Menlo Park, California, with a nano-fabrication center in Palo Alto, a content team in Los Angeles and Auckland, New Zealand, and industrialization center in Suzhou, China. History The company was founded in 2014 as a spin-off from HP Labs. Its research into the holographic display concept under HP was published by ''Nature'' in 2013. CEO David Fattal explained that its diffraction system would address shortcomings with other mobile 3D display systems, such as being able to be seen by multiple viewers at once, using the display in its original 2D mode with no loss of resolution and not requiring CPU-intensive eye tracking. The company foresaw uses of its technology in mobile devices, automobiles, and medical applications. In May 2016, Leia announced a partnership with Altice to market a smartphone featuring its technology. In 2017, Red Digital Cinema annou ...

Image Processing
An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensional picture, that resembles a subject. In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term “image” may refer specifically to a 2D image. An image does not have to use the entire visual system to be a visual representation. A popular example of this is of a greyscale image, which uses the visual system's sensitivity to brightness across all wavelengths, without taking into account different colors. A black and white visual representation of something is still an image, even though it does not make full use of the visual system's capabilities. Images are typically still, but in some cases can be moving or animated. Characteristics Images may be two or three-dimensional, such as a pho ...

Depth Map
In 3D computer graphics and computer vision, a depth map is an image or image channel that contains information relating to the distance of the surfaces of scene objects from a viewpoint. The term is related (and may be analogous) to ''depth buffer'', ''Z-buffer'', ''Z-buffering'', and ''Z-depth''. tp://ftp.futurenet.co.uk/pub/arts/Glossary.pdf Computer Arts / 3D World Glossary Document retrieved 26 January 2011. The "Z" in these latter terms relates to a convention that the central axis of view of a camera is in the direction of the camera's Z axis, and not to the absolute Z axis of a scene.

Fujifilm FinePix Real 3D Series
The Fujifilm FinePix Real 3D W series is a line of consumer-grade digital cameras designed to capture stereoscopic images that recreate the perception of 3D depth, having both still and video formats while retaining standard 2D still image and video modes. The cameras feature a pair of lenses (offset left-to-right by a baseline that approximates the distance between an average pair of human eyes), and an autostereoscopic display which directs pixels of the two offset images to the user's left and right eyes simultaneously. Methods are included for extending or contracting the stereoscopic baseline (the distance between the left and right images), albeit with an asynchronous timer or manually depressing the shutter twice. The dual-lens architecture also enables novel modes such as simultaneous near and far zoom capture of a 2D image. The remainder of the camera is similar to other compact digital cameras.

Plenoptic Camera
A light field camera, also known as a plenoptic camera, is a camera that captures information about the ''light field'' emanating from a scene; that is, the intensity of light in a scene, and also the precise direction that the light rays are traveling in space. This contrasts with conventional cameras, which record only light intensity at various wavelengths. One type uses an array of micro-lenses placed in front of an otherwise conventional image sensor to sense intensity, color, and directional information. Multi-camera arrays are another type. Holograms are a type of film-based light field image. History Early research The first light field camera was proposed by Gabriel Lippmann in 1908. He called his concept "integral photography". Lippmann's experimental results included crude integral photographs made by using a plastic sheet embossed with a regular array of microlenses, or by partially embedding small glass beads, closely packed in a random pattern, into the sur ...
