对人眼视觉特性的研究表明,人眼在水平与垂直方向上的视角比为16:9,所以宽银幕电影及即将到来的高清晰度彩电屏幕的宽高比的标准都定为16:9,以符合这一人体生理特性,达到最佳视觉效果。康佳集团公司出品的 T3289W 型16:9宽屏彩电采用最新数码视窗技术,具有双视窗、多画面、画中画(PIP)及画外画(POP)等多种视窗显示方式,给人以全新的视觉感受。其核心技术之一就是采用时间压缩电路。采用时间压缩电路的原因,一是为了与现有的4:3图象兼容,二是为了实现双视窗及画外画等技术。
Research on the visual characteristics of human eyes shows that the aspect ratio of the human eye in the horizontal and vertical directions is 16: 9, so the aspect ratio of the widescreen movie and the upcoming high definition color TV screen is set at 16: 9 , In order to meet the physiological characteristics of the human body, to achieve the best visual effects. Konka Group produced T3289W 16: 9 widescreen color TV with the latest digital window technology, with dual-window, multi-screen, picture-in-picture (PIP) and painting (POP) and other window display, giving a brand new visual feeling. One of its core technologies is the use of time compression circuitry. The reason for using the time compression circuit is that, in order to be compatible with the existing 4: 3 image, the second is to realize technologies such as double-window and painting.
