Despeckle — reduces the amount of stray spots (specks, etc.) on an
image. This option is for bi-tonal images only.
NOTE: The Contrast, Brightness and Despeckle options can be roughly
adjusted by using the slider bar. You can more precisely adjust
these options by entering a value in the entry field or use the up
and down arrows to obtain the desired value .
Scan Output — select the type of output required. (Bitonal produces
the smallest file size; 256-gray produces the largest file size).
• Bi-tonal: each image will be processed as a single-page TIFF file
using CCITT Group 3 or 4 compression (for black and white
images).
• 16 gray: each image will be processed as a single-page TIFF file
using JBIG compression (for 16-level gray scale images).
• 256 gray: each image will be processed as a single-page TIFF file
using JPEG compression (for 256-level gray scale images) or as a
JPEG file with JPEG compression. For 256 gray, it is recommended
you use JPEG/JPEG compression.
Sharpening — used to accentuate the fine details of an image.
• Normal: used to enhance the detail of an image, which contains
small print.
• Low: used to enhance images containing dot matrix text and/or
images printed with shaded or colored backgrounds using halftone
screens. This option reduces background noise.
• Photo: if the image is comprised mainly of photographs.
• Photo & Text: if the image is a mix of text, line art, and
photographs (i.e., check camera-sorter films).
• Text: if the image is mostly text.
Rotate — choose one of the following options to specify images will be
rotated when displayed:
• None: to process the image in the original orientation.
• 90° Clockwise: to process the image rotated 90° to the right.
• 180° Clockwise: to process the image rotated 180° to the right.
• 270° Clockwise: to process the image rotated 270° to the right.
