An onboard camera is a camera placed upon a moving object, such as a vehicle. In motor racing, onboard cameras are often used to give a better perspective from the driver's point of view, whilst in films, these cameras are designed to increase the intensity and action of a specific scene. Onboard cameras were used in movies such as ''Le Mans'' and ''The Fast and the Furious'' series, for this purpose. Much of the original development work which led to the onboard cameras used today was performed by Australia's Seven Network during the early 1980s. In 1983 Channel Seven were asked to provide onboard (or in-car, its U.S. name) cameras for the NASCAR series. The original, Channel Seven, development team of John Porter and Peter Larsson moved to the states and formed Broadcast Sports Technology Inc.. BST then proceeded to recruit other staff from Channel Seven, notably Michael Katzmann. Throughout the years BST covered all the major US motor racing series, as well as branching into America's Cup and Olympic sailing onboards. The first time a live onboard camera was used in a Formula One race was at the 1985 German Grand Prix, where one was attached to François Hesnault's Renault. Previously, cameras had only been mounted to F1 cars during testing, but since then, more and more cameras have been fitted. Since 1998, all Formula One cars have been fitted with at least three onboard cameras (usually more) and they form an integral part of the television coverage. As with US onboard coverage, F1 used a helicopter as a local satellite to pick up the transmission from the cars and re-broadcast it to the truck / local production center. This was initially shifted to a ground based analog system, with variable results, and more recently to a ground based digital solution which is now the norm. Onboard cameras are now commonplace in other top motorsports including the World Rally Championship and MotoGP. == Dashcams == (詳細はUnited States in the 1980s and 1990s; then, as technology became cheaper, ubiquitous in civilian use in Russia as a form of sousveillance, inasmuch as Russian courts prefer video evidence to eyewitness testimony, but also as a guard against police corruption and insurance fraud.〔(Why Russians are obsessed with Dashcams )〕 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「onboard camera」の詳細全文を読む スポンサード リンク
