X To configure the Background panel settings
1
From the VRS Adjustment Controls, select the Background panel.
2
Select the Enable Smoothing check box to turn on the background smoothing
feature, which you can use to modify the background of a color image. If this
check box is not selected, the background region of a color image is not
altered when it is processed.
3
Select an option for processing images with color backgrounds:
• White: All background color is changed to white.
• White: All background color is changed to white.
• Black: All background color is changed to black.
• Automatic: All background pixels are smoothed to the same value,
representing an average of the detected background colors. This selection
is appropriate only when minor variations exist in the background color.
Note
If you select Automatic, the results may vary, according to the color
detected in the background region of the scanned document.
4
If you selected Automatic in the previous step, the results will be directly
affected by the Snap to White setting, as follows:
• If Snap to White is selected and the image background is close to white,
• If Snap to White is selected and the image background is close to white,
the resulting background color is white.
• If Snap to White is selected and the background is not close to white, the
background color is set to a smoothed color value determined by the
scanner.
• If Snap to White is not selected, the background color is set to a smoothed
color value representing an aggregate of the detected background colors.
Note
The Snap to White feature is not available with all scanners.

Do one of the following to adjust the Background Color Sensitivity setting:
• Move the slider to the left to decrease the level of background region
• Move the slider to the left to decrease the level of background region
processing in color documents. A low value decreases the likelihood that a
pixel will be determined to be part of the image background.
• Move the slider to the right to increase the level of background region
processing in color documents. A high value increases the likelihood that
a pixel will be determined to be part of the image background.
• Click the arrows of the text box to increase or decrease the Background
Color Sensitivity value.
• Click in the Background Color Sensitivity text box and type a value.
