The scan converter allows us to record a much higher quality image than what we would get from pointing a camera at the subject ' s monitor 扫描变换器使我们能记录的图像质量比从安放在显示器前的摄像机高很多。
For studies using software , a scan converter provides a direct feed from the subject ' s computer screen to tape recorders and monitors on the observer side 对于研究使用软件,扫描变换器把项目电脑的屏幕直接输入到摄录存储器和观察者这边的监视器上。
The scanning converter comprises five parts : video signal decoding , data reconstruction , progressive video signal encoding , control signal producing and communication 扫描转换器包含了电视信号的解码、解码后数据的重构、逐行信号编码、控制信号的产生以及通信五部分。
This dissertation first discusses the two - dimension interpolation algorithm and coordinate rotation digital computer algorithm involved in the process of designing system . then the paper particularly probes into the research and development of b - mode digital scan converter , m - mode digital scan converter and graphic circuitry in the digital scan conversion system 本文首先对系统设计过程中引入的二维线性插值算法和坐标旋转数字计算算法进行了讨论,然后着重论述了数字扫描变换系统中的b型数字扫描变换器、 m型数字扫描变换器和图形界面电路的原理、设计与实现。
