YUV/RGB conversion formulas

Following are the conversion formulas from RGB to YUV and from YUV to RGB. See YUV and color space conversion.

   From RGB to YUV

   Y = 0.299R + 0.587G + 0.114B
   U = 0.492 (B-Y)
   V = 0.877 (R-Y)

   It can also be represented as:

   Y =  0.299R + 0.587G + 0.114B
   U = -0.147R - 0.289G + 0.436B
   V =  0.615R - 0.515G - 0.100B


   From YUV to RGB

   R = Y + 1.140V
   G = Y - 0.395U - 0.581V
   B = Y + 2.032U
