YCbCr pixel data will be divided according to the perception of the human eye of the substance. By separating information about brightness out of the color information, that is, the element will store the Y value of the point image brightness (Luminance) Cb is blue elements that cut the brightness (Y – B) and Cr is red elements that cut the brightness (R – Y). The difference between the value of green with emits (Cg) it is not necessary to store the value of that because the Cr + Cg + Cb is constant, so if you know the value of Cb and Cr, just look for the Cg, it can however storing data, whether it be in the RGB color system, the image of a point, or YCbCr color systems, it can be converted to another has always been. If you want to convert from RGB to color systems color system can convert the YCbCr equation 2.2. [15] [17]
