Region of Interest (ROI)
Region of Interest (ROI)
You can narrow the active image area (field of view) by defining a specific area or region of
interest.
This is especially useful for increasing decode speed, improving threshold, and selecting
the desired symbol from multiple symbols the FOV.
Notes
:
1. When using video output, the
Region of Interest
image will only be shown in triggered
video mode. When in live video mode, the entire image from the image sensor will be
shown.
2. If external camera is in use, the command will range check for the camera and will
allow a larger row and column size then the sensor has. The overall operation of the
Window of Interest will not be effected if a larger row or column size is selected.
3. The
Region of Interest
can be disabled by setting all values to
0
or setting the
Region of Interest
area to equal the image sensor area.
Caution:
Region of Interest
will shrink the field of view and therefore could cause symbols
to be missed in dynamic applications.
