Claim 3:
4. The method of claim 1, wherein said determining the brightness evaluation value component corresponding to each group based on the brightness histogram component corresponding to the group and the number of pixels in the image to be processed comprises:
obtaining a number of pixels for each possible value of the pixel data in the group based on the brightness histogram component corresponding to the group;
multiplying each possible value of the pixel data with the number of pixels corresponding to the possible value, and determining a sum of results of the multiplying for all possible values as an accumulated brightness value component corresponding to the group; and
dividing the accumulated brightness value component corresponding to the group by the number of pixels in the image to be processed, to obtain the brightness evaluation value component corresponding to the group.
