六十年代末,高速电视的概念仅停留在这画幅凝结时间上,即所谓高速电视是指画面在电视摄象管靶面上的曝光时间小于普通电视。随着电视技术的发展,特别是磁带录相技术的发展,高速电视除追求短暂的画面凝结时间外,主要集中在设法提高电视画幅频率以便获得更多的运动事件变化的信息。今天,高速电视画幅频率已成为衡量高速系统特性的一项极其主要的指标,也是选用高速电视设备于快速运动分析的一个极重要的参数。
In the late 1960s, the concept of high-speed television only stayed on this frame setting time. The so-called high-speed television means that the exposure time of the picture on the television camera tube target surface is less than that of ordinary television. With the development of television technology, especially the development of videotape recording technology, high-speed television has focused more on information seeking ways to increase the frequency of television frames in order to obtain more changes in motion events besides pursuing short frame clotting time. Today, high-speed television frame frequency has become an extremely important indicator of high-speed system characteristics, and is also a very important parameter for the selection of high-speed television equipment for rapid motion analysis.
