Background Suppression
This function removes unwanted background from the images to exclude them from the measurement target.
Setting the BGS level converts images at the lower limit value or below to density 0 and images at the upper
limit or above to density 255 so that only an image of density within the range lower limit value to upper limit
value is extended and turned into a measurement target having 0 to 255 tones. When you move the cursor, an
image of the image at the cursor position is displayed at the cursor position with unwanted background
removed. Set the BGS level while monitoring the image on screen.
Example: Set the lower limit value to 100 and upper limit value to 220

ue range of 100 to 220 are treated as the
measurement target and are extended to
