Binarization Threshold Value Mode
The below 3 types of binarization threshold value modes are selectable.
Standard
・・・
Based on the brightness distribution of image, the threshold value is calculated
automatically inside the camera.
※
Set a parameter of binarization threshold value (address 42) to 512d
Barcode
・・・
Based on the brightness distribution of edge areas in image, the threshold value is
calculated automatically inside the camera.
The object which has a lot of edges such as barcode and character can be binarized
with less influences of the fluctuation in flat areas and/or backgrounds. (Refer to the
below drawing)
※
No effect if there are only horizontal edges.
※
Set a parameter of binarization threshold value (address 42) to 512d.
Manual
