This setting is used to smooth the image. It is useful when the scanned original is "noisy"
(i.e. color disturbance, graininess and non-area uniformity). Valid values range from 0
to 12.
Blurring is not the opposite of sharpening: sharpening works on the image's edges only,
whilst blurring smoothes out the whole color or gray tone areas. In fact, these two
settings combined, by blurring away noise in the image first and then sharpening the
result, may be used to further enhance the image. Observe below the same example as
before, with blur and sharpening applied. Note that now there is no "augmented noise"
in the text area, with respect to when only sharpening was applied.
