Setting Reading Conditions
BGS Levels
This function suppresses the object's background to stabilize reading, eliminating noise and
other disturbances.
Set the upper and lower limits of the BGS density while monitoring the image.
Densities lower than the set lower limit will be converted to 0 (i.e., areas with densities lower than
that value will not be read), densities higher than the set upper limit will be converted to 255, and
intermediate densities will be graded between 0 and 255. In other words, only the areas with den-
sities between the set lower and upper limits will be read.
Example: Lower limit set to 150 and upper limit set to 220

Image areas with densities of
149 or lower will not be read
and the density will be changed to 0.
Only image areas with densities
between 150 and 220 will be read.
The whole image is graded from 0
to 255.
