In fact it works in just about the same way. For examples which show how this is related to blur see, Image Processing By Interpolation and Extrapolation. For example lets blur a simple image then attempt to sharpen it again to remove the blur. Particularly notice the extra thickening that resulted at the corner of the two lines at the very top of the image, as well and the near disappearance of the thin lines. Even repeating the operation or increasing the size of the area of the sharpen will not help return the image back to the exact original as you have basically lost the finer detail from the image blurring.
