6.10. Binarization 

[XCL-5005]

Configure this setting with BINARIZE. This setting 
performs the binarization processing. You can set the 
threshold value of binarization with a parameter. It can 
be set within the range of 240 to 3900 (when 12 bits). If 
the image output bit is changed, each of the setting 
ranges of the threshold value will be 60 to 975 (when 10 
bits) and 15 to 243 (when 8 bits). 
However, when setting the parameter, convert the 
threshold value setting into a value of 12 bits even if you 
use the camera in 8 bits or 10 bits. 

 Reference

The edge detection image can be emphasized by using a 
combination of edge detection and binarization 
processing.
