Using the Noise Tab
The Noise tab gives you a set of filters that enhance image quality and remove excessive
speckling. As you adjust the Noise settings, the effects are applied to the image in the VRS
Viewer window. You can fine-tune the settings until the image appearance meets your quality
standards.
Note:
The Noise tab settings are intended for black and white scanning; they have no effect on
grayscale scanning.
