• To improve decodability when the FoV includes codes with different levels of con-
trast:
HDR disabled
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, because Exposition Time can be reduced when HDR is
enabled. The allowed Exposition Time (T
(X) divided by the line speed (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
HDR enabled
) must be less than the code resolution
