This function compresses characters and backgrounds on the document separately. So using this function on the document which contains almost text characters, the file size becomes smaller while leaving the characters as they are. Meanwhile, this function is not appropriate for scanning photographs or figures, because such drawings are recognized as background and compressed as such, so the qualities of such images will deteriorate.
