模拟视频图象增强装置有选择地压缩总的动态范围,而增强感兴趣的那些边缘或细微部分,从而改善技术图片的外观。模拟视频电路就是用来提供廉价的实时图象处理技术。该系统包括一个带透镜的视频摄象机,并与视频监视器连接。如图所示的电路加在监视器上就能起模拟视频增强作用。视频信号从监视器的同步信号分离 Analog video image enhancements selectively compress the overall dynamic range to enhance those edges or subtle parts of interest, improving the appearance of technical images. Analog video circuits are used to provide inexpensive, real-time image processing. The system includes a video camera with lens attached to the video monitor. As shown in the circuit on the monitor can play the role of analog video enhancement. The video signal is separated from the monitor’s sync signal
