The following processing is available.
(a) Smooth (1/2)
Reduces snow noise. It is effective especially at high magnification, where originally
image itself has defocusing limited by spatial resolution. In this case, noise can be
reduced without image defocusing.
For lower magnification images, the processing may cause loss of sharpness.
(b) Sharpen (1/2)
Increases image sharpness.
Snow noise may be intensified if the image includes noise.
