Threshold Value
Usage:
Fixed
works better when decode time must be as short as possible and the
reflectance and illumination of the symbol area is uniform and unchanging.
Otherwise
Adaptive
is the preferred mode.
Definition:
This value switches the image processing threshold mode between the
Adaptive
and
Fixed
modes.
An adaptive routine sets the light/dark threshold from data acquired from
the current read. A fixed mode applies the same gray scale threshold value
to each and every symbol.
Generally,
Adaptive
gives better results than
Fixed
.
Unlike
Adaptive
,
Fixed
applies the same value consistently to each and
every symbol.
