Contrast % sets the image contrast by adjusting the difference
between black and white, thereby making an image sharper or softer.
In a low-contrast setting, the difference between black and white is small,
so the image is softer. In a high-contrast setting, the difference between
black and white is large, so the image is clearer. Select a contrast value
from 1 to 100. The default is 50.
Contrast 1
Contrast 60
Contrast 100
Adjust the contrast setting by dragging the Contrast sliding bar to the left
or right to achieve the desired contrast setting, or you can enter a value
(1 to 100) in the Contrast text box. Scan the document to check the
contrast.
Threshold used to convert a grayscale image to a bi-tonal (1
bit/pixel) image. The thresholding value ranges from 0 to 255. A low
threshold value produces a lighter image, and can be used to subdue
backgrounds and subtle, unneeded information. A high threshold value
produces 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, or you can enter a
value (0 to 255) in the Threshold text box. Scan the document to check
the threshold.
