Practical digital video cameras were also enabled by advances in video compression, due to the impractically high memory and bandwidth requirements of uncompressed video. [8] The most important compression algorithm in this regard is the discrete cosine transform (DCT), [ 8 ] [ 9 ] a lossy compression technique that was first proposed in 1972 ...
The first consumer camera with a liquid crystal display on the back was the Casio QV-10 developed by a team led by Hiroyuki Suetaka in 1995. The first camera to use CompactFlash was the Kodak DC-25 in 1996. [52] The first camera that offered the ability to record video clips may have been the Ricoh RDC-1 in 1995.
The Sanyo Xacti HD1 was the first such unit, combining the features of a 5.1 megapixel still camera with a 720p video recorder with improved handling and utility. Canon and Sony have introduced camcorders with still-photo performance approaching that of a digicam, and Panasonic has introduced a DSLR body with video features approaching that of ...
The Mavica electronic still camera recorded FM-modulated analog video signals on a newly developed 2" magnetic floppy disk, dubbed the "Mavipak". The disk format was later standardized as the "Still Video Floppy", or "SVF". The Canon RC-701, introduced in May 1986, was the first SVF camera (and the first electronic SLR camera) sold in the US.
Edwin H. Land introduces the first Polaroid instant camera. 1949 – The Contax S camera is introduced, the first 35 mm SLR camera with a pentaprism eye-level viewfinder. 1952 – Bwana Devil, a low-budget polarized 3-D film, premieres in late November and starts a brief 3-D craze that begins in earnest in 1953 and fades away during 1954.
The basis for digital video cameras is metal–oxide–semiconductor (MOS) image sensors. [1] The first practical semiconductor image sensor was the charge-coupled device (CCD), invented in 1969 [2] by Willard S. Boyle, who won a Nobel Prize for his work in physics. [3]
Camera bodies, and sometimes lenses, were increasingly made in plastic rather than the metals of the earlier types. As the costs of mass production came down, so did the price and these cameras became very popular. This type of format and camera was more quickly superseded for amateurs by the advent of digital video cameras in the 2000s.
