Using the Clarity Tab
This section describes the Clarity tab of the VRS Interactive Properties dialog box. The
Clarity tab provides options to adjust the contrast, brightness, and gamma values for
an image. In general, a high Contrast value enhances faint text and lines in your
documents. Since Brightness increases or decreases the overall density of your
images, increasing the brightness level can clear up dark shaded documents. Finally,
Gamma Correct allows you to adjust images created with incorrect gamma encoding.
Note With the Böwe Bell + Howell Spectrum series scanner, the Clarity tab features
are available only when you scan in black and white or in grayscale mode. When you
use this scanner in color mode, the Clarity tab will be disabled if the VRS Interactive
Properties dialog box appears as the result of an exception or a QC mode setting.
Also, the Clarity tab will be visible if you select Preview mode, but no image will be
available to display in the viewer.
