The Kodak Digital Camera System is a series of digital single-lens reflex cameras and digital camera backs that were released by Kodak in the 1990s and 2000s, and discontinued in 2005. They were all based on existing 35mm film SLRs from Nikon and Canon. The range included the original Kodak DCS, the very first commercially available digital SLR. ==History== In 1975 Kodak engineer Steven Sasson invented the first digital still camera, which used a Fairchild 100 x 100 pixel CCD.〔(How Kodak invented the digital camera in 1975 )〕〔(Digicamhistory: 1970s )〕 By 1986 Kodak had developed a sensor with 1.4 million pixels.〔(History of the Digital Camera )〕 A number of other inventions were made to increase usability, including improvements in sensor technology, the first Raw image format DCR, and usable host software. The original Kodak DCS was launched in 1991, and was based on a stock Nikon F3 SLR with digital components. It used a 1.3-megapixel Kodak KAF-1300 sensor, and a separate shoulder-mounted processing and storage unit. The DCS 200 series of 1992 condensed the storage unit into a module which mounted onto the base and back of a stock Nikon F801s SLR. The module contained a built-in 80 megabyte hard drive and was powered with AA batteries. It was followed by the upgraded DCS 400 series of 1994, which replaced the hard drive with a PCMCIA card slot. The DCS 400 series included the 1.5-megapixel DCS 420, and the 6-megapixel Kodak DCS 460, which retailed for $28,000 on launch.〔(The New York Times, July 1995: Kodak Sees a Future where Film is Optional )〕 In common with Kodak's later 6-megapixel models, the DCS 460 used the award-winning APS-H Kodak M6 sensor.〔(Business Wire, October 1995, Kodak Imaging Sensor wins award from Technical Image Press Association )〕 A modified version of the DCS 420 was also sold by the Associated Press as the Associated Press NC2000.〔(Eamon Hickey, January 2005, "A look back at the NC2000" )〕 In parallel with the DCS 400 series Kodak also sold the analogous Kodak EOS DCS range, which was based on the Canon EOS-1N SLR. With the exception of the original DCS 100, these early models did not include LCD preview screens. Kodak's subsequent models integrated the digital module with the camera body more thoroughly, and included LCD preview screens and removable batteries. The DCS 500 series of 1998 was also based on the Canon EOS-1N, and comprised the 2-megapixel DCS 520 and the 6-megapixel DCS 560, which initially had a suggested retail price of $28,500.〔(Business Wire, September 1998, Kodak Professional Extends Portfolio of Digital Cameras )〕 These models were also sold by Canon, as the Canon D2000 and D6000 respectively, and were the first digital SLRs sold under the Canon name. Kodak used the same electronics package for the DCS 600 series, which was based on the Nikon F5. The DCS 600 range included the Kodak DCS 620x, a high-sensitivity model with an upgraded indium tin oxide sensor and a cyan-magenta-yellow Bayer filter, which had a then-unique top ISO setting of ISO 6400. Kodak's concluded the initial DCS range with the DCS 700 series, which comprised the 2-megapixel DCS 720x, the 6-megapixel DCS 760, and the 6-megapixel DCS 760m, which had a monochrome sensor. By the time of launch, Kodak faced competition from the popular Nikon D1 and Nikon D1x,〔(Digital Photography Review: Kodak DCS 760 Review, July 2001 )〕 which were physically smaller and cheaper. The DCS 760's initial list price was $8,000. Kodak final generation of DCS cameras was launched with the Kodak DCS Pro 14n, a 14-megapixel full-frame digital SLR, in 2002, and continued with the upgraded DCS PRO SLR/n in 2004. These two cameras were based on a Nikon F80 body, and were considerably more compact than previous Kodaks. They used sensors designed by Belgian imaging company FillFactory. The DCS PRO SLR/n was also accompanied by the Canon-compatible DCS PRO SLR/c, which was based on a Sigma SA9 SLR. Kodak discontinued the SLR/n and SLR/c in May 2005,〔(Kodak.com, May 2005, NOTICE OF DISCONTINUANCE )〕 to concentrate on compact digital cameras and high-end medium format digital backs for Leaf, among others. Kodak continued to design and manufacture digital imaging sensors, including the full-frame 18-megapixel KAF-18500, which is used in the Leica M9 digital rangefinder, until its digital sensor division was sold to Platinum Equity in 2012. This digital sensor company now operates under the name Trusense.〔(Kodak's image-sensor spin-off gets a name: Truesense )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kodak DCS」の詳細全文を読む スポンサード リンク
