很多人一想到立体电视,立即就会联想到劣质的图象、眼睛疲乏和常常是不成功的奇特印象。但立体电视仍然是视频技术中最吸引人的项目之一。这并不令人惊奇,因为立体电视不仅对广大电视观众具有极大的吸引力,而且对电视游戏一类的活动也具有极大的吸引力。另外,立体电视在科研、医学和工业方面也具有广阔的应用前景。立体电视系统成败的关键在于立体效果,而不方便的程度和观众所要负担的费用等问题,只是稍为次要问题。下面我们介绍一下目前正在研制中的几种立体电视系统,并分析一下它们的优缺点。
Many people think of stereoscopic television, immediately think of poor images, eyes tired and often strangely unsuccessful impression. However, stereoscopic television remains one of the most attractive projects in video technology. This is not surprising given that stereoscopic television is not only extremely appealing to the general audience, but also appealing to such activities as video games. In addition, stereoscopic television also has broad application prospects in scientific research, medicine and industry. The key to the success or failure of a stereoscopic television system is its three-dimensional effect. The inconvenience and the costs borne by the audience are just a few minor problems. Here we introduce several types of stereoscopic television systems currently under development and analyze their advantages and disadvantages.
