The RGB mode is often used on the monitor, which is different from the pal or NTSC video standard.
Conversion between YUV and yiq
The conversion formula between YUV, yiq, and RGB is as follows:
Y = 0.299r + 0.587G + 0.114b
U = B ━ y
V = r y
I = 0.877 (R-Y) cos33 platinum 0.492 (B-Y) sin33
Q = 0.877 (R-Y) sin33 + 0.492 (B-Y) cos33
RGB is composed of three primary colors: R, G, and B. Similarly, YUV is composed of three elements: Y, U,
