DSP Operation

Binarization

Executes the binarizion process. The threshold value can 
be set in the range from 240 to 3900 (in 12 bits). When 
the image output bit is changed, the range of the 
threshold value setting will be 60 to 975 (in 10 bits) and 
15 to 243 (in 8 bits). 
Note that the threshold value setting must be converted 
into a value of 12 bits even if you use the camera in 8 bits 
or 10 bits.

Reference

The edge detected image can be accentuated by 
combining the edge detection and the binarizion 
process.
