Sometimes an item is scanned with the brightness and contrast set to be too
light or too dark. For example, a note written with a light pencil may need to
be scanned darker to improve legibility.
The following figure shows the brightness and contrast options. Contrast is
only available for Color and Grayscale configurations.
To adjust the brightness and contrast:
1.
Drag the
Brightness
slider to the left to make the item darker or to the
right to make the item lighter.
2.
Drag the
Contrast
slider to the left to decrease the contrast or to the right
to increase the contrast.
You can also type a number directly into the brightness or contrast setting
boxes, or click the up and down arrows next to the box to increase or
decrease the setting.
3.
Click
Reset
to return the settings to their original numbers
