4.2.2 Other Image Options

Binarization This is the process of converting a

grayscale or color image to a bi-tonal
image. There are several different
methods of performing this conversion.
Two of the options are Dynamic

Threshold and Fixed Processing.
Dynamic Threshold: Selecting

Dynamic Threshold allows the scanner

to dynamically evaluate each document
to determine the optimal threshold value
to produce the highest quality image.
This is used to scan mixed document
containing faint text, shaded background,
or color background with a single setting.
If Dynamic Threshold is selected,
Threshold, Brightness, and Contrast are
not available.

Fixed Processing: Used for black-and­white and other high contrast documents.
A single level is set to determine the
black-and-white transition. The threshold
is programmable over the entire density
range. Fixed Processing sets Contrast
to 0. If Fixed Processing is selected,
Contrast is not available.

User’s Manual

4-7

Threshold Used to convert a grayscale image to a

bi-tonal image. The value ranges from 0 to

255. A low threshold value produces a
lighter image, and can be used to subdue
backgrounds and subtle, unneeded
information. A high threshold value produces
a darker image, and can be used to help pick
up faint images.
Adjust the threshold setting by dragging the
Threshold sliding bar to the left or right to
achieve the desired threshold setting.

Resolution

A good control of the resolution results a
good detail of an image that scans. The
resolution is measured by dots per inch
(dpi). Normally, the greater the dpi number,
the higher the resolution and the image file
size. Be aware that greater resolution takes
more time to scan, and more disk space for
the scanning image. For your information,
an A4 size color image scanned at 300 dpi at
True Color mode consumes approximately 25
MB of disk space. A higher resolution
(usually means over 600 dpi) is only
recommended when you need to scan a
small area at True Color mode.

Choose a resolution value from the drop
down list. The default value is 200 dpi.
Available resolutions are 75, 100, 150,
200,300, 400 and 600. Or you may choose
your desired value by clicking the box in the
right side of the drop down list and press the
arrow key to select your desired value and
then click the Add button to include it in the
drop down list.

4.3 The Compression Tab

The Compression tab allows you to compress your scanned
image and choose the level of compression. Bi-tonal images
are normally compressed using CCITT standard called Group 4
(G4). Color and grayscale images are often compressed using
JPEG technology. Move the JPEG Quality slider to the right or
left to increase or decrease the level of compression. Note the
greater the compression level, the lower image quality. Default
is 50%.

Note that the compression depends on your image editing
application. If your image editing application does not support
the type of compression format, then either a warning
message will appear or the image quality of the compressed file
will not be acceptable.

JPEG (Joint Photographic Editor Group). This group developed
and lent their name to a file compression standard for color and
grayscale images that is widely used by scanners, and software
applications. On Microsoft Windows-based systems, a file with
the extension .jpg has normally been compressed using this
standard.

For scanning color or gray images, the following compressions
are available:

y None
y JPEG

For scanning B&W images, the following compressions are

available:

y None

4.5.3 Relative to Document

Relative to Document: (used for batches of same-sized

documents)
This option allows you to crop different areas on your

documents and deliver these images in B&W, Gray, or Color
separately. For example, there are applications which require
you to store the entire document in B&W and a part of the
document in color to save storage space. This is useful for
documents where a photograph, or signature appears in a
consistent area on the document such as resumes, and so on.

The following procedure describes how to reproduce the entire
document in B&W and a portion of document (picture) in color.

1. On the Paper tab, choose “Relative to Document” or “Fixed

Batch Scan
Setting

•Batch Scan

To increase the scanning speed, the
scanner first scans a few pages of your
document and then sends these scanning
data to the application. Therefore, during

scanning, the numbers of pages been

scanned on the scanner is somehow
different with the numbers of pages
displayed on your computer screen.
Choose this mode if you wish to complete
your scanning task at the fastest speed.

•Page Scan

If you choose Page Scan, during scanning,
the scanner will first scan only one page of
your document and then send the scanned
data to the application and then scan the
next page and send the next data to the
application, and so on. Therefore, in this
mode, the scanning speed is slower yet this
helps to keep the same scanning progress
between the scanner and your computer
screen.
