Background Suppression
Background suppression (BGS) excludes the background of the measurement
object from the measurement process for easier measurement. BGS can be
set separately for Image 0 and Image 1.
Set the upper and lower limits of the BGS density while monitoring the image.
BGS changes image areas with densities below the lower limit to 0, and image
areas with densities above the upper limit to 255. Image areas with densities
between the lower and upper limits are graded from 0 to 255 so that only
images with densities between the lower and upper limits are measured.
Example: Lower limit set to 100 and upper limit set to 220
• Images with densities set to less than 100 are not measured and the den-
sity becomes 0.
• Only images with densities between 100 and 220 are measured and the
images are graded between 0 and 255.
