Claim 7:
8. The high dynamic range image processing method according to claim 1, wherein the maximum luminance modification value maximum_maxrgb1 of the HDR image is determined according to the following formula:, maximum_maxrgb1
  
   =
  
  
   
    {
    
     
      
       
        
         MaxRefDisplay
         ,
         
          MAX
          >
          MaxRefDisplay
         
        
       
      
      
       
        
         MAX
         ,
         
          MIN
          ≤
          MAX
          ≤
          MaxRefDisplay
         
        
       
      
      
       
        
         MIN
         ,
         
          MAX
          <
          MIN
         
        
       
      
     
     ,, wherein
MaxRefDisplay represents maximum display luminance that is of a reference display device and that is applicable before the dynamic range of the HDR image is adjusted, MIN represents a preset hierarchy threshold, and MAX represents the maximum reference value.
