Claim 13:
14. The apparatus according to claim 12, wherein the scaling coefficient in the linear model corresponding to the chroma block is represented by:, α
    =
    
      
        
          C
          Lmean
        
        -
        
          C
          Rmean
        
      
      
        
          L
          Lmean
        
        -
        
          L
          Rmean
        
      
    
  
  ,, wherein α is the scaling coefficient in the linear model corresponding to the chroma block, CLmean is the average value of the chroma values in the first chroma set, CRmean is the average value of the chroma values in the second chroma set, LLmean is the average value of the luma values in the first luma set, and LRmean is the average value of the luma values in the second luma set.
