In digital imaging, a pixel, pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device. In most digital display devices, pixels are the smallest element that can be manipulated through software.
Leica Camera AG is a German company that manufactures cameras, optical lenses, photographic lenses, binoculars, rifle scopes and microscopes. The company was founded by Ernst Leitz in 1869, in Wetzlar, Germany.
The light field is a vector function that describes the amount of light flowing in every direction through every point in space. The space of all possible light rays is given by the five-dimensional plenoptic function, and the magnitude of each ray is given by its radiance. Michael Faraday was the first to propose that light should be interpreted as a field, much like the magnetic fields on which he had been working. The phrase light field was coined by Andrey Gershun in a classic 1936 paper on the radiometric properties of light in three-dimensional space.
A digital camera back is a device that attaches to the back of a camera in place of the traditional negative film holder and contains an electronic image sensor. This lets cameras that were designed to use film take digital photographs. These camera backs are generally expensive by consumer standards and are primarily built to be attached on medium- and large-format cameras used by professional photographers.
A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
Image resolution is the detail an image holds. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail.
The EOS 1D Mark II is a professional 8.2 megapixel digital single lens reflex camera (DSLR) camera body produced by Canon. The EOS 1D Mark II was the successor of the EOS 1D and was itself replaced by the Canon EOS-1D Mark III in 2007. It was Canon's first dual-card slot EOS camera with one CF slot and one SD slot that was meant easily to use two dominant card types and have a assurance that once a small sized primary and faster CF slot is full, camera can be used to take photographs when recording was continued on secondary and slower card in critical moment. It also now had wireless capabilities. When paired with the new Canon WFT-E1, you could transfer images to a PC using an FTP server.
The Nikon D1 is a digital single-lens reflex camera (DSLR) made by Nikon Corporation introduced on June 15, 1999. It featured a 2.7-megapixel image sensor, 4.5-frames-per-second continuous shooting, and accepted the full range of Nikon F-mount lenses. The camera body strongly resembled the F5 and had the same general layout of controls, allowing users of Nikon film SLR cameras to quickly become proficient in using the camera. Autofocus speed on the D1 series bodies is extremely fast, even with "screw-driven" AF lenses.
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.
Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce images focused by a lens, as opposed to an exposure on photographic film. The digitized image is stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital printing. It is a form of digital imaging based on gathering visible light.
OmniVision Technologies Inc. is an American subsidiary of Chinese semiconductor device and mixed-signal integrated circuit design house Will Semiconductor. The company designs and develops digital imaging products for use in mobile phones, laptops, netbooks and webcams, security and surveillance cameras, entertainment, automotive and medical imaging systems. Headquartered in Santa Clara, California, OmniVision Technologies has offices in the US, Western Europe and Asia.
Sony Corporation produces professional, consumer, and prosumer camcorders such as studio and broadcast, digital cinema cameras, camcorders, pan-tilt-zoom and remote cameras.
In digital photography, the image sensor format is the shape and size of the image sensor.
Exmor is the name of a technology Sony implemented on some of their CMOS image sensors. It performs on-chip analog/digital signal conversion and two-step noise reduction in parallel on each column of the CMOS sensor.
A mirrorless camera is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera, but may have an electronic viewfinder. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount.
A back-illuminated sensor, also known as backside illumination (BI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance.
Lytro, Inc. was an American company founded in 2006 by Ren Ng which developed some of the first commercially available light-field cameras. Lytro began shipping its first generation pocket-sized camera, capable of refocusing images after being taken, in 8 GB and 16 GB versions on February 29, 2012. In April 2014, the company announced Lytro Illum, its second generation camera for commercial and experimental photographers. The Lytro Illum was released at $1,600. The Illum has a permanently attached 30–250mm f/2.0 lens and an articulated rear screen. In the fall of 2015, Lytro changed direction, announcing Immerge, a very-high-end VR video capture camera with companion custom compute server. Immerge was expected to ship in 2016, and be useful to studios trying to combine CGI-based VR with video VR.
The Nikon D800 is a 36.3-megapixel professional-grade full-frame digital single-lens reflex camera produced by Nikon Corporation. It was given a Gold Award by Digital Photography Review.
The Nokia 808 PureView is a Symbian-powered smartphone first unveiled on 27 February 2012 at the Mobile World Congress. It is the first smartphone to feature Nokia's PureView Pro technology, a pixel oversampling technique that reduces an image taken at full resolution into a lower resolution picture, thus achieving higher definition and light sensitivity, and enables lossless digital zoom. It was one of the most advanced camera phones at the time of its release in May 2012.
The Canon EOS 5DS and EOS 5DS R are two closely related digital SLR cameras announced by Canon on February 6, 2015. Both are professional full-frame cameras with 50.3-megapixel sensors, the highest of any full-frame camera at the time of announcement. The only difference between the two models is that the sensor of the "R" version includes an optical filter that cancels out the effects of a standard optical low-pass filter. This distinction is roughly similar to that between Nikon's now-replaced D800 and D800E. Canon stated that both the 5DS and 5DS R will not replace the older EOS 5D Mark III; therefore, both the 5DS and 5DS R will have their new positions in Canon's DSLR camera lineup.
