超高清视频系统被认为是未来提供高度真实感的广播服务的潜在候选者。本文将讨论构建4000行扫描的实验性超高清视频系统的设计思想。根据真实感与视角的关系确定扫描参数。该摄像系统是基于两个2.5英寸的四个电荷耦合器件(电荷耦合器件)图像采集技术开发的。绿色使用8M像素的ccd，红色和蓝色分别使用一个。四路电荷耦合器件分束系统结合了二维像素偏移量，与电荷耦合器件形成拜耳色采样图案。并研制了4000行扫描线显示系统。它类似于成像系统，使用四个8M像素的LCD来实现4000条扫描线系统，红蓝各一条，绿色两条，对角像素偏移。水平视角大于1000，距离320英寸的标准观察位置为3米。(7 x 4米)屏幕。
An ultrahigh-definition video system is considered to be a prospective candidate for future broadcasting services providing a high sensation of reality. This paper will discuss the design considerations in the construction of an experimental ultrahigh-definition video system with 4000 scanning lines. The scanning parameters were determined based on the relationship between the sensation of reality and the viewing angle. The camera system was developed based on the four-CCD (charge-coupled device) image-acquisition technology: two 2.5-in. 8M-pixel CCDs are used for green, and one each for red and blue. The four-CCD beam-splitting system incorporates two-dimensional pixel offset to form a Bayer color-sampling pattern with the CCDs. A 4000-scanning-line display system was also developed. It is similar to the imaging system, which uses four 8M-pixel LCDs to realize a 4000-scanning-line system, one each for red and blue, and two for green with diagonal pixel offset. The viewing angle is more than 1000 horizontally, at a standard viewing position of 3 m from a 320-in. (7 x 4 m) screen.
