本文提出了一种使现在的电视接收机能实现三维立体图象的最新技术。两幅三维物体图象的产生和发送是这样安排的,一幅用隔行扫描电视系统的奇数场,另一幅则用偶数场。附加在发射端和接收端的一个并不昂贵的电子逻辑组件控制视频信号的多路传输和分离,而无须对电视信号标准作任何修改。为了实现三维图象,这里应用了一种场掩同步光阀(FMSS),它克服了早先提出的使用彩色滤色片的限制。此外,它还易于实际制作。由于这个方案必须在现行的带宽范围内工作,所以,为了获得立体视觉,图象清晰度要有所降低。(一)三维系统的基本要求我们利用混合两幅由双眼所看到的稍有不同的图象来感知三维物体。第三维(深度)的感觉是由于两眼以不同的角度观察同一物体而产生的。为了达到三维
This article presents the latest technology that enables today’s television receivers to realize three-dimensional stereoscopic images. The creation and transmission of two three-dimensional object images is arranged in such a way that an odd field of an interlaced television system and an even field are used for the other. An inexpensive electronic logic attached to the transmitter and receiver controls the multiplexing and demultiplexing of video signals without any modification to the television signal standard. To achieve three-dimensional images, a Field Mask Synchrotron Light Valve (FMSS) is applied that overcomes the previously proposed limitation of using color filters. In addition, it is easy to actually produce. Because this scheme must work within the current bandwidth, so in order to obtain stereoscopic vision, image clarity to be reduced. Basic Requirements for 3D Systems We perceive 3D objects by blending two slightly different images seen by both eyes. The third dimension (depth) is the result of the two eyes looking at the same object at different angles. In order to achieve three-dimensional
