A brief summary:
YUV is a type of image format used in applications such as videos, pictures, cameras, etc. It is actually the name of the color space common to all "YUV" pixel formats. Unlike the RGB format (red-green-blue), YUV is represented by a "luminance" component called Y (equivalent to grayscale) and two "chromaticity" components, called U (blue projection) and V (red projection), hence the name.
What does each YUV stand for?
Y represents the brightness component: if only Y is displayed, the image will look like a black and white photo.
U represents the chroma component: the blue part of the photo is removed from the brightness (Y).
V represents the chrominance component: the red part of the photo is removed from the brightness (Y).

Sharing is also a way to deepen your understanding of the problem again. It may not be comprehensive, but it is definitely useful and will continue to be improved later~
