Sony camera

                   Cyber-shot is a line of digital cameras made by Sony. The Cyber-shot range is well known for its proprietary InfoLithium battery pack[1], the trademark Carl Zeiss lenses and overall design. Also, all Cyber-shot cameras accept Sony's proprietary Memory Stick or Memory Stick PRO Duo flash memory. Some high-end models have also supported CompactFlash. Newer Cyber-shot cameras support SD and SDHC. All Cyber-shot models have a DSC prefix in their names, which is an acronym for "Digital Still Camera".
                   July 7, 2010 - Sony unveiled Sony DSC-TX9 and DSC-WX5 that are the world's smallest 3D cameras, capturing 3D images with a single lens system using a sweeping motion. Sony also introduced DSC-T99 14.1MP CCD camera for about $250. The three cameras above offer 3D Sweep Panorama feature, which lets us take panoramic pictures in one press-and-sweep motion. The high-speed burst of frames is stitched together using innovative processing techniques to automatically create detail-packed 3D panorama. These images can be seen in 2D or 3D on compatible 3D television. The cameras available since September 2010.

Panasonic camera

                                   Lumix is Panasonic's brand of digital cameras, ranging from pocket point-and-shoot models to digital SLRs. Many Lumix models are fitted with Leica lenses that have been designed by Leica's German optical engineers and are assembled in Japan, some are rebadged as Leica cameras with different cosmetic styling. Leica had a similar relationship with Minolta in the past, where late model Leica SLRs (and some 35mm point and shoot models) were strongly based on Minolta bodies.
                                    Most Lumix cameras use different releases of the Panasonic Venus Engine for digital image processing; the original version was followed by II, III, IV, HD (2008), V (2009), and VI, HD II (2010).
                                   Panasonic produces all of Leica's branded digital point and shoot cameras in Japan, but not film cameras, the Leica M8 or Leica M9 digital rangefinder cameras, or the Digital Modul R digital camera back for the Leica R9 film SLR.
                                Some cameras come in several colours, indicated by a suffix letter: K is black, S silver, A blue, R red, W white. Most lower-price cameras have small sensors of about 10.2 mm / 1/2.5". More expensive ones often have sensors of about twice the area, 14.1 mm to 15.4 mm / 1/1.65" to 1/1.8". dSLRs and Micro Four Thirds cameras have much larger sensors. Larger sensors produce a better signal-to-image-noise ratio and better dynamic range.
                       Some Panasonic and Leica cameras are more or less the same. The differences, other than the obvious exterior styling, are in the camera firmware. Different application software is also supplied by the two companies with the cameras. Claims regarding differing quality control or weatherproofing are unsubstantiated.
                     The Leica and Panasonic cameras produce the same RAW image, but will process white balance, noise reduction, etc. differently for jpeg output. Lumix cameras are less expensive than their Leica counterparts due to the companies' marketing strategies.

Olympus camera

               Olympus has a long history in camera and lens design. In 1936, Olympus introduced its first camera, the Semi-Olympus I. The first truly innovative camera series from Olympus was the PEN models, launched in 1959. Half-frame format, allowing 72 pictures of 18 × 24 mm format on a standard 36 exposure roll of film, made PEN cameras compact and portable for their time.
              The PEN system design team, led by Yoshihisa Maitani, later created the OM system, a full frame professional 35 mm SLR system designed to compete with Nikon and Canon's bestsellers. The OM system introduced a new trend towards more compact cameras and lenses, being much smaller than its competitors and presenting innovative design features such as through-the-lens flash automation. Eventually the system included 14 different bodies and approximately 60 Zuiko-branded lenses.
             However, Olympus did not move into the autofocus market in the way their competitors did, ultimately leading to their decline as a maker of professional film camera systems[citation needed].
            The company is a leading manufacturer of digital cameras, with a large range of compact digital cameras. Olympus is the designer of the Four-Thirds System standard for digital single-lens reflex camera design and development. The Four-Thirds system includes the first consumer-grade digital SLRs to feature live preview, a feature now adopted by all major DSLR makers.
           Olympus' flagship DSLR camera is the E-5 released in 2010. Olympus is also the largest manufacturer of Four-Thirds lenses under the Zuiko brand; these lenses are known for their good optical quality and compactness. Olympus cameras originally only took the xD-Picture Card proprietary format (which it shares with Fujifilm), which has driven away some consumers. Recent cameras have included compatibility with the Secure Digital (SD) card format with their compact range and Compact Flash with their dSLR's in hopes of winning back customers. The most recent development is Olympus' focus on the Micro Four Thirds system

Canon camera

The name Canon began in 1934 with a prototype for Japan’s first-ever 35 mm camera with a focal plane shutter. It was named 'Kwanon' by Goro Yoshida after the Buddhist bodhisattva Guan Yin known in Japanese as Kannon.
Canon is a manufacturer of business and consumer imaging products which includes printers, scanners, binoculars, compact digital cameras, film and digital SLR cameras, and lenses.

The Business Solutions division offers print and document solutions for small and medium businesses, large corporations and governments. These include multi-functional printers, black and white and color office printers, large format printers, scanners, black and white and color production printers, as well as software to support these products.

Lesser known Canon products include medical, optical and broadcast products, including ophthalmic and x-ray devices, broadcast lenses, semiconductors, digital microfilm scanners, and Handy Terminal Solutions.
For many years, Canon were the principal makers of the print-engines found in industry-standard laser printers. The first models of Apple LaserWriter, and the equivalent products made by HP, used the Canon LBP-CX engine. The next models (LaserWriter II series, LaserJet II series) used the Canon LBP-SX engine. Later models used the Canon LBP-LX, LBP-EX, LBP-PX engines and many other Canon print engines.
Between printer models based on the same Canon print engine, many parts (such as toner cartridges, fuser units, roller assemblies) are interchangeable.
Canon laser printers use cartridges.

Video camera

A video camera is a camera used for electronic motion picture acquisition, initially developed by the television industry but now common in other applications as well. The earliest video cameras were those of John Logie Baird, based on the electromechanical Nipkow disk and used by the BBC in experimental broadcasts through the 1930s. All-electronic designs based on the cathode ray tube, such as Vladimir Zworykin's Iconoscope and Philo T. Farnsworth's Image dissector, supplanted the Baird system by the 1940s and remained in wide use until the 1980s, when cameras based on solid-state image sensors such as CCDs (and later CMOS active pixel sensors) eliminated common problems with tube technologies such as burn-in and made digital video workflow practical.

Video cameras are used primarily in two modes. The first, characteristic of much early television, is what might be called a live broadcast, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required. The second is to have the images recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but optical disc media, hard disk, and flash memory are all increasingly used. Recorded video is used in television and film production, and more often surveillance and monitoring tasks where unattended recording of a situation is required for later analysis.
Modern video cameras have numerous designs and uses, not all of which resemble the early television cameras.

Kodak camera

                                  Disc film was a still-photography film format aimed at the consumer market, and introduced by Kodak in 1982.The film was in the form of a flat disc, and was fully housed within a plastic cartridge. Each disc held fifteen 11 × 8 mm exposures, arranged around the outside of the disc, with the disc being rotated 24° between each image.

The system was primarily a consumer-oriented product, and most cameras were self-contained units with no expansion capability. The cameras were very simple to load and unload, and were generally completely automated. The cassette had a built-in dark slide to prevent stray light reaching the film when the disc was removed.

As the film was rotated on a disc instead of over a spool, the cassette was very thin, as were most of the cameras. The completely flat nature of the format also led to the (potential) advantage of greater sharpness over spool-based cassette formats (such as 110 and 126 film). Disc film has a very thick acetate base, comparable with 4×5" sheet film, which holds the film much flatter than the other formats.

Disc film did not prove hugely successful, mainly because the image on the negative was only 11 mm by 8 mm, leading to generally unacceptable grain and poor definition in the final prints. The film was intended to be printed with special 6-element lenses from Kodak, but many labs simply printed discs with standard 3-element lenses used for larger negative formats. The resulting prints often disappointed the consumer.

There were several different manufacturers of Disc film. Kodak produced films throughout the complete lifespan of the format, but 3M, Konica and Fuji also produced Disc film. While Kodak film was always eponymous, 3M and Konica made Disc film for many third parties, branded with the retailers logo. As with most photographic film, the country of manufacture is the best giveaway to the make. Agfa never produced Disc film.

Kodak's newest ideas with sharp fine-grained negative film were always tested in Disc format first, typically being one or two generations ahead of the equivalent 135 film.

Nikon camera

In January 2006 Nikon announced the discontinuation of all but two models of its film cameras, focusing its efforts on the digital camera market. It continued to sell the low-end FM10 (manufactured by Cosina) until 2009, and still offers the high-end F6 (manufactured by Nikon). Nikon has also committed to service all the film cameras for a period of ten years after production ceases.
Between 1983 and the early 2000s a broad range of compact cameras were made by Nikon. Nikon first started by naming the cameras with a series name (like the L35/L135-series, the RF/RD-series, the W35-series, the EF or the AW-series. In later production cycles, the cameras were double branded with a series-name on the one and a sales name on the other hand. Sales names were for example Zoom-Touch for cameras with a wide zoom range, Lite-Touch for ultra compact models, Fun-Touch for easy to use cameras and Sport-Touch for splash water resistance. After the late 1990s, Nikon dropped the series names and continued only with the sales name. Nikon's APS-cameras were all named Nuvis.

The cameras came in all price ranges from entry-level fixed-lens-cameras to the top model Nikon 35Ti with titanium body and 3D-Matrix-Metering.
