The following processing are available.
(a) Smooth (1/2)
(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, nnoise can be
reduced without image defocusing.
For lower magnification images, the processing may cause loss of sharpness.

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.
Snow noise may be intensified if the image includes noise.
(c) Edge Enhance (1/2)
Similar but stronger effect of above Sharpen.
(d) Invert
Inverse contrast.
(e) Gamma (15 to +5)
Plus value of Gamma suppress white contrast and brought up dark part.
Minus value increases contrast.
Minus value increases contrast.
