Backlight Correction Removes shadows from photos that have too much background light. Descreening Removes the ripple pattern that might appear in subtly shaded image areas, such as skin tones. This option improves results when scanning magazines or newspapers. (The results of descreening do not appear in the preview image, only in your scanned image.) Dust Removal Removes dust marks from your originals automatically. Text Enhancement Sharpens the appearance of letters in text documents. Auto Area Segmentation Makes black and white images clearer and text recognition more accurate by separating the text from the graphics. Threshold Adjusts the level at which black areas in text and line art are delineated, improving text recognition in OCR (Optical Character Recognition) programs. Color Enhance Enhances the shades of the color you select in the scanned image. This setting is available only if you select Grayscale or Black & White as the Image Type setting. Brightness Adjusts the overall lightness and darkness of the scanned image. Contrast Adjusts the difference between the light and dark areas of the overall scanned image. Saturation Adjusts the density of colors in the overall image. Gamma Adjusts the midtone density of the scanned image. Edge Fill Corrects shadowing around the edges of the image by filling the shadows with black or white. Correct Document Skew Corrects skewed originals, image contents, or both.
