Applies real time digital image processing to the scanning image. 
 
 
 
 
 

(1) Processing selection box 

Selects a processing 

 

• Smooth : 

Applies pixel averaging spatial filtering. Reduces snow noise. 
Effective especially in case of high magnification image where the beam spot size is 
larger than pixel size. For low magnification having fine structures, it may cause some 
degradation of sharpness.   
Two processing intensity selectable. 

Increases sharpness of scanning image. 
Two processing intensity selectable. 
It may increase noise when the original image contains snow noise. 

• Edge Enhance :   

Similar but strong processing as Sharpen. 

• Invert :   

Color inversion. Resules negative image. 

• Gammma :   

Gamma correction. 
-5 to +5 selectable.

(3) Option Signal button 

Opens the Opt Signal Processing dialog window for analog signal processing of optional 
detector signal.
