, because 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
):

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
