The range in which to enhance the contrast and the brightness range to extract are set for the Background
Suppression item. The Background Suppression item works as described below to suppress the background
for the specified brightness range.
• Enhancing Contrast

to enhance the contrast.
• Background Suppression
Input values from 0 to the lower limit are converted to level 0 and input values between the upper limit and 255 are
converted to level 255 to remove as the background any places that are not within the specified brightness range.
