| 摘 要： | 采用模拟电路完成视频信号色彩校正器的研制,其设计原理为:从存有彩色失真的视频信号中分离色度信号,进而解调出三基色信号,进行偏色校正。之后,通过PAL制编码电路,获得无彩色失真的视频信号。该校正器利用原同步信号生成新的色同步信号,保证了校正后彩色信号时基的稳定。

| Abstract: | Applying analogue electric circuit, we developed a video signal colour corrector. Its work principle is that three primary colours signal were demodulated from chrominanec signal which was separated from colour distortional video signal, and then correction of culour cast was carried out. Finally, a no colour distortional video signal was obtained by PAL systematical coding circuit. Stabilization of time base under correction could be maintained by applying original synchronous signals for producing newly burst. |
