Claim 3:
4. The detection method according to claim 2, wherein the acquiring the light leakage weight values corresponding to the pixel point sets comprises:
computing a light leakage weight value corresponding to each of the pixel point sets in accordance with a equation:, weight
  =
  
   
    
     
      ∑
       
     
     
      i
      =
      1
     
     n
    
    ⁢
    Wi
   
   N
  
 

wherein weight is the light leakage weight value corresponding to the pixel point set, Wi is a light leakage weight value of a block where an i-th pixel point in the pixel point set is located, N is a number of pixel points included in each block, and n is a number of pixel points included in the pixel point set.
