![一个彩色影像的图和一个彩色影像只有Y成份的图、只有Cb成份的图、和只有Cr成份的图。同时注意的是只有Y成份的图基本上来说就是彩色影像那张图的灰阶本。that the white snow is represented as a middle value in both Cr and Cb; that the brown barn is represented by weak Cb and strong Cr; that the green grass is represented by weak Cb and weak Cr; and that the blue sky is represented by strong Cb and weak Cr.](/Images/godic/202502/21/Barns_grand_tetons_YCbCr_separation1009.jpg") ![A visualization of YCbCr color space](/Images/godic/202502/21/YCbCr1009.GIF") ![The CbCr plane at constant luma Y'=0.5](/Images/godic/202502/21/YCbCr-CbCr_Scaled_Y501010.png") ![RGB to YCbCr conversion](/Images/godic/202502/21/CCD1010.png") YCbCr或Y'CbCr有的时候会被写作：YCBCR或是Y'CBCR，是色彩空间的一种，通常会用于影片中的影像连续处理，或是数字摄影系统中。Y'和Y是不同的，Y就是所谓的流明（luminance），表示光的浓度且为非线性，使用伽马修正（gamma correction）编码处理。Y'为颜色的亮度（luma）成分、而CB和CR则为蓝色和红色的浓度偏移量成份。 Y'CbCr不是一种绝对的色彩空间，是一种针对RGB信息所做的编码。真正的颜色显示是根据实际RGB色盘（colorant）来决定的。因此Y'CbCr所表示的值只有在标准RGB色盘或是ICC数据（ICC profile）有提供的时候才能计算。

![A color image and its Y, CB and CR components. The Y image is essentially a greyscale copy of the main image.](/Images/godic/202502/21/Barns_grand_tetons_YCbCr_separation1010.jpg") YCbCr, Y′CbCr, or Y Pb/Cb Pr/Cr, also written as YCBCR or Y′CBCR, is a family of color spaces used as a part of the color image pipeline in video and digital photography systems. Y′ is the luma component and CB and CR are the blue-difference and red-difference chroma components. Y′ (with prime) is distinguished from Y, which is luminance, meaning that light intensity is nonlinearly encoded based on gamma corrected RGB primaries. |
