• Click in the Color Content Aggressiveness text box and type a value.
4 Select the Color Object Size Detection check box if you want to the function
that is used to identify small amounts of color on otherwise bitonal
documents. If this check box is not selected, the scanner may not detect small
amounts of color.
5 Adjust the Color Object Size Aggressiveness setting by doing one of the
following:
• Move the slider to the left to decrease the likelihood of detecting small
amounts of color.
• Move the slider to the right to increase the likelihood of detecting small
amounts of color.
• Click the arrows of the text box to increase or decrease the Object Size
Aggressiveness value.
• Click in the Color Object Size Aggressiveness text box and type a value.
6 Select the Enable check box to turn on the Color Background Saturation
features 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.
7 You can select from the following Background Saturation options for
processing images with color backgrounds:
• White: All background color is changed to white.
• Black: All background color is changed to black.
• Smooth: All background pixels are smoothed to the same value.
8 If you selected Smooth in the previous step, the outcome 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,
the resulting background color is white. The exact white color is
determined by the selections in the scanner panel interface.
• 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 that is an aggregate of the detected background colors.
9 Adjust the Color Saturation Aggressiveness setting by doing one of the
following:
• 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.
