• To improve decodability when the FoV includes codes with different levels of con-
trast:
HDR disabled HDR enabled
In the example above, when HDR is disabled only two out of four codes are decoded.
After enabling HDR, all four codes are decoded.
•In high speed applications, bec
ause Exposition Time can be reduced when HDR is
enabled. The allowed Exposition Time (T
exp
) must be less than the code resolution
(X) divided by the line speed (LS):
T
exp
< (X/ LS)
HDR
disabled
HDR
enabled
In the example above, C128 13 mils (0.33 mm) codes at a distance of 200 mm must be
decoded. When HDR is disabled, good image contrast is obtained with the Exposition
