PAL制电视信号编码采用的是频谱交炽原理,如果仍利用以往的Y-C分离方法就难以达到完善的分离,会在图像上形成Y、C成分间的相互串扰,造成失真以及亮度和色度细节的损失。为了充分挖掘PAL制的潜力,获得高质量的重显图像,研究适合于此制式的、行之有效并易于实现的、新的Y-C分离方式是有实际意义的。
PAL system television signal encoding is the principle of the spectrum of cross-Chi, if you still use the previous YC separation method is difficult to achieve perfect separation, will form Y, C components of the image cross-talk between each other, resulting in distortion and brightness and color detail Loss. In order to fully exploit the potential of the PAL system and obtain high-quality, re-imagined images, it is of practical significance to study a new Y-C separation approach that is well-suited and easy to implement.
