You can speed up your decode rate and lower your chances of reading the wrong symbol
by narrowing the region of interest—the pixel area that is evaluated during a read attempt.

If your application uses only 1D symbols,you can narrow
the imager's 640 axis to 200 pixels. Since only a narrow
512 X 512
strip of the imager's field of view is required to decode a
1D symbol, 200 pixels is sufficient. The area above and
below the 200 pixels is ignored, reducing the amount of
640
image processing required, and increasing decode speed.
The diagram to the left represents the imager array
(1024 x 640 for far field and 1024 x 640 for near field). In
640
the default decode zone, all 1024 x 640 pixels are candidates
for decoding.
