翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Philips DP70 ： ウィキペディア英語版 Philips DP70 The DP70 is a model of motion picture projector, of which approximately 1,500 were manufactured by the Electro-Acoustics Division of Philips between 1954 and about 1968.〔http://in70mm.com/dp70/story/index.htm〕 It is notable for having been the first mass-produced theater projector in which 4/35 and 5/70 prints could be projected by a single machine, thereby enabling wide film to become a mainstream exhibition technology, for its recognition in the 1963 Academy Awards, which led to it being described as "the only projector to win an Oscar" (though this is technically incorrect, because the award was actually a Class 2 Oscar Plaque), and for its longevity: a significant number remain in revenue-earning service at the time of writing (February 2014). ==Research and development== Small-scale attempts had been made to use wide film for commercial theater exhibition around the time of the conversion to sound, of which Fox Grandeur was technologically the closest to the format the DP70 was designed to facilitate the launch of, two decades later. One of the reasons these early systems failed to establish wide film as an industry standard was that the projectors developed for them were incompatible with the existing 4/35 standard. In order to be able to project both, therefore, theaters had to be equipped with two sets of projectors, which involved significant extra cost and in some cases architectural modifications to projection booths. The DP70 (DP stands for "Double Projector") was invented and developed by a team headed by Jan-Jacob Kotte of Philips between 1952–54, as part of the Todd-AO system. A core objective of the project was to create a single machine that could project both the Todd-AO 5/70 format and the 4/35 format which was, and was likely to remain, the dominant standard for theater exhibition. 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「Philips DP70」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
