Adjustments tab: color
or grayscale
The options available depend on the Scan As selection you made on
the General tab. The following options are based on a Scan As
selection of Color or Grayscale.
Brightness — changes the amount of white in the color or grayscale
image.
Contrast — makes the image sharper or softer.
Red — changes the amount of red in the color image. Does not apply
to grayscale images.
Green — changes the amount of green in the color image. Does not
apply to grayscale images.
Blue — changes the amount of blue in the color image. Does not apply
to grayscale images.
• Adjust these settings by dragging the slider bar to the left or right,
entering a value in the text box or using the up/down arrows. While
each setting may effect the underlying gamma table, Brightness and
Contrast are the options that provide the widest range of changes.
Background Smoothing — use this option when you are scanning
documents or forms with a background color(s). Background
Smoothing produces images with a more uniform color. This option
improves image quality and reduces file size.
• Method: select one of the following:
- None - no background smoothing will be done.
- Automatic - background smoothing is applied to the actual color.
- Change to White - identifies the background color and substitutes
that color with white.
