4 In the Contrast text box, VRS displays the current contrast setting. To change
the setting, do one of the following:
Click the arrows on the Contrast text box to increase or decrease the
contrast level.
Click in the Contrast text box and type in a value.
Move the Contrast slider control left or right to select a value.
5 From the Advanced Clarity group, select the Enable Advanced Clarity check
box to turn on the feature that applies advanced processing to identify the
optimal contrast and brightness settings for challenging documents.
Note Advanced Clarity is available only for documents that are scanned in
bitonal mode. It is also available for documents that are scanned in color
mode and then output as bitonal using the Automatic Color Detection
feature. For more information, refer to Using the Color Panel on page 70.
6 If you enable Advanced Clarity, the following settings are available:
Analyze Color: For pages that contain a color background or color text,
this option produces optimal black and white images by including subtle
color content variations in the page evaluation. Otherwise, only grayscale
variations are evaluated.
Note While this setting is active, the color analysis may adversely affect
scanner performance.
Ignore Pictures: Ignores pictures or photos when VRS evaluates the page
content. As a result, the clarity improvements are applied to other (non-
picture) content on the page.
7 If you enable the Advanced Clarity feature, move the slider to the left or right
to select the desired level of intensity, as follows:
Move the slider to the left (toward 1) to apply minimal processing.
Move the slider toward the midpoint (3) to apply more aggressive
processing.
Move the slider toward 5 to apply the most aggressive processing (which
may be required in special cases).
Note The default Intensity setting is appropriate for most document types. If
you change the setting, it persists until you change it again or apply a profile
that uses a different setting.
