3.9.5  Signal Processing 
 
Processing of the image signal is available on a live image.   
For SE signal, digital processing, spatial filtering, gamma control and inversion can be applied. 
In addition, analog signal processing is available for an optional detector signal. 
 
(1)  Digital signal processing 
Use SIGNAL PROCESSING block on the operation panel to apply digital signal processing.

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.
