Threshold
thresholding is used to convert a grayscale image into a
binary (1 bit/pixel) image. The thresholding value ranges from 0 to 255.
The default is 90. A low threshold value will produce a lighter image, and
can be used to subdue backgrounds and subtle, unneeded information.
A high threshold value will produce a darker image, and can be used to
help pick up faint images.
Adjust the threshold setting by dragging the Threshold sliding bar to the
left or right to achieve the desired threshold setting. Scan the document
to check the threshold.
Lighten, Normal and Darken are used as quick sets to adjust the
threshold. Lighten = 72, Normal = 90 and Darken = 128.
