come from? In modern color TV system, usually use three-tube color camera or color CCD camera to camera, and then the color image of the captured signal by color separation, amplification and correction to get RGB, and then through the matrix transformation circuit to obtain the luminance signal Y and two chromatic aberration signal r-y (that is U), b-y (that is, V), The final transmitter encodes three signals of brightness and chromatic aberration, which are sent out using the same channel. Th

In modern color TV system, usually use three-tube color camera or color CCD camera to camera, and then the color image of the captured signal by color separation, amplification and correction to get RGB, and then through the matrix transformation circuit to obtain the luminance signal Y and two chromatic aberration signal r-y (that is U), b-y (that is, V), The final transmitter encodes three

meanings that are inherited and inherent. These implications have a direct impact on how the site's visitors understand the site, even if the impact is just a subconscious level. The colors you choose may or may not be useful for the brand identity you are trying to create. In the second part, we discuss the color terms: hue (what color, such as blue or red), chroma (color contains a single standard color composition, lack of white, add black or g

and chromatic aberration by three signals, and sends out the same channel. This method of color representation is called YUV color space representation. This shows that RGB and YUV belong to the color space (or "color space"), if not clear the concept of color space. Two, the advantages and disadvantages of RGB and YUV 1.RGB lack of good compatibility with early Black-and-white display systems. Therefore, many electronic appliances manufacturers commonly adopted the practice is to convert RG

recording will undoubtedly have a higher image quality. In practice, however, this is often not the case, because it greatly widens the bandwidth of the video signal, increases the cost of the associated equipment, and the second is incompatible with the current black and white. The three primary colors are combined into luminance (Y) and chroma (U,V) signals in a certain proportion, and the relationship between them is as follows: In order to enable
