色度信号

For example, a watermark is embedded in the luminance component and a cyclically shifted version thereof in the chrominance component of a video signal.

例如，将水印嵌入在视频信号的亮度分量中，并将其循环移位版本嵌入在视频信号的色度分量中。

The basic information consists of luminance information and chrominance difference signals. During the composition into one signal, the chrominance signals can interfere with the luminance. Therefore, the television technique has to adopt appropriate modulation methods to eliminate the interference between luminance and chrominance signals.

基本信息由亮度信息色差信号组成，由于在合成中，色度信号可能会干扰亮度信号，因此，还要采用适当方法消除色度信号和亮度信号之间的干扰。

Spectral aliasing is caused by interference between two frequencies such the luminance and chrominance signals.

光谱混叠是由两个频率如亮度和色度信号频率之间的干扰引起。

The basic video bandwidth required to transmit luminance and chrominance signals is 4/2 MHz for the NTSC standard.

NTSC标准中亮度信号和色度信号传输所要求的基本视频带宽是4.2MHz。

It is quick and precise in measuring and getting the analysis results,displays the parameters of phase and amplitude value of signals in imaging way,and has friendly man-machine interface,and all of these offer an intuitive and convenient means for the real-time monitoring and the analysis of the parameters of differential gain distortion and differential phase distortion in video chroma vector signals.

形象地显示信号相位、幅值等参数的方式和友好的人机界面的设计，为实时监控、分析色度矢量信号的微分增益失真和微分相位失真等参数，提供了直观、便捷的测量手段。

Also, as we'll see shortly, we can reduce chrominance bandwidth considerably via subsampling, without much loss in visual perception.

另外，正如我们马上就会看到的那样，我们可以通过子采样的方法，在视觉效果不会出现较大损失的前提下，大大减小色度信号带宽。

Now, if we filter a 4:4:4 YCbCr signal by subsampling the chroma by a factor of 2 horizontally, we end up with 4:2:2 YCbCr.

现在，如果我们通过在水平方向上对色度信号进行因数为2的子采样，对一个4：4：4 YCbCr 信号进行滤波，于是将得到4：2：2 YCbCr 。

You could use the 'desaturate' command on the image – this would keep the image in RGB mode, where each of the colour channels can accommodate 256 shades, so now we potentially have 256x256x256 = 16.7 million different colours.

在图片上使用&饱和度功能&命令，可使图片保持在RGB模式，每个颜色信号通道都所容纳256个色度可以组成 256x256x256 = 1670万个不同颜色。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
