question about luma*2 #34

Open qihaoliu0 opened 1 year ago

qihaoliu0 commented 1 year ago

Hi! about RCAS, why it is calculated as L = B*0.5 + (R*0.5) + G? I searched Luma at wiki。 B's coefficient seems is always <= 1.2, why using 0.5 as B's coefficents in code? 

  // Luma times 2.
  AF1 bL=bB*AF1_(0.5)+(bR*AF1_(0.5)+bG);
  AF1 dL=dB*AF1_(0.5)+(dR*AF1_(0.5)+dG);

I'm very confused about this , cloud you please teach me? Thanks so much!
