This function allows you to adjust the image brightness, making it lighter or darker.
You can adjust the brightness setting from –100 to 100 by dragging the Brightness
sliding control bar. The default is "0." The smaller the number, the darker the image.
Scan the document and check the brightness.
A darker setting is recommended for blurred character documents. With a brighter
setting, background noise in a color document disappears.
The Contrast option sets the image contrast by adjusting the difference between
black and white, thereby making an image sharper or softer.
You can adjust the contrast setting from –100 to 100 by dragging the Contrast sliding
control bar. The default is "0." Scan the document and check the contrast.
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.
