Claim 7:
8. The method of claim 7, wherein obtaining the corrected blurring value of the pixel comprises:
obtaining a first corrected offset and a second corrected offset for the row within the preset blurring kernel shape based on the actual blurring kernel radius and a correction correspondence between blurring kernel offsets and blurring kernel radii, wherein the correction correspondence corresponds to the preset blurring kernel shape;
obtaining a third horizontal summing value corresponding to the first corrected offset in the first horizontal summed area table and obtaining a fourth horizontal summing value corresponding to the second corrected offset in the first horizontal summed area table for the row within the preset blurring kernel shape;
obtaining a corrected sum of pixel values for the row within the preset blurring kernel shape based on the third horizontal summing value and the fourth horizontal summing value; and
summing up the corrected sum of each row within the preset blurring kernel shape to obtain the corrected blurring value of the pixel.
