Abstract
In one embodiment, the method includes determining a reference pixel group including a pixel to be filtered. The reference pixel group includes at least three successive pixels. The method further includes applying weight factors to at least each of the three successive reference pixels. The weight factors are different according to pixel position. A filtered value is obtained by summing at least the three weighted successive pixels and applying a shift operation to the sum for dividing the sum.
