22 VISIONEER STROBE XP 100 SCANNER INSTALLATION GUIDE
DeScreen—Select this option when scanning a picture from a
newspaper or magazine article, or other items that contains images
with patterns or dots. Scans of patterns or dots sometimes have a
distorted or wavy appearance. The scanner scans the item to
compensate for the patterns and dots, and produces a clearer image.
The following example shows the effect of descreening a scanned
image from a magazine article.
The scanning may slow down a bit when descreen is selected. You
dont need to select this option when scanning photographs. The
DeScreen setting does not apply to the Black/White mode.
Gamma—The gamma setting adjusts the range of midtone colors
on an image. By changing the gamma you can adjust midtone levels
without losing details from the lightest or darkest areas. You use the
gamma correction to achieve precise color matching of the original
image and how it looks on your computer monitor. Because the
computer cannot always transmit the exact color information to the
hardware, you may have to make some color adjustments using the
gamma feature.
In most cases, however, the default gamma setting works fine and
normally does not need to be adjusted.
