ERASING PERIPHERAL SHADOWS FOR COPYING(ERASE)
Overview
The erase function is used to erase shadows around the edges of copies that occur when copying thick originals or books.
If a ratio setting is used in combination with an erase setting, the erase width will change according to the selected ratio. This function erases the parts of the image where shadows tend to form, but does not detect shadows and erase only the shadows.
