Bgs Levels - Omron V530-R160E User Manual

SECTION 5
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
