AutoCrop
—Select this option to let the scanner automatically
determine the size of the item being scanned. For example, if you
put a photo in the middle of the glass, the scanner will
automatically determine the size of the photo. When AutoCrop is
selected, the scanner makes two passes—the first pass senses the
item’s size, and the second pass scans the image. This option
overrides the Page Size menu selection.
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 scanning may slow down a bit when this option is selected. You
don’t need to select this option when scanning photographs. The
DeScreen setting does not apply to the Black/White mode.
Gamma
—Drag the slider to improve how the colors in a scanned
image look on your monitor. Gamma correction allows you to
achieve precise color matching. 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.
The default Gamma setting works fine in most cases and normally
does not need to be adjusted.
