Best possible processing results under difficult reading conditions
Under difficult reading conditions (for example, with oil-smeared or needle-punched codes),
use the correct dimension when saving the codes. This achieves the best possible
processing results.

Default Description
Note
When using image enhancement, the processed
image section may be slightly reduced per operation.
With the aid of the preview function, make sure that
the codes to be read are completely located in the
filtered image section.
(Each image filter for which the X/Y width is speci-
fied reduces the image section by (X-1) and (Y-1)
pixels, respectively.)
ISO/IEC 16022 ISO/IEC 16022
