2.3 The Image Tab
The Image tab allows you to choose the front side and (or) the rear side of your document, the
type of image, andconfigure several basic scan settings. Note that except for the resolution, you
can set individual scan settings for the front side and the rear side. For example, all settings in
the Image tab, Compression tab and Color Dropout tab can be set individually for the front and
the rear side. However, the settings in the Paper tab, the Options tab (Rotation, Separation,
Enhancement), and the Settings tab have to be the same for the front and rear side.

Front/Rear Auto Color Detection:
Click to automatically detect and scan the front or the rear page of your color document in color
image mode. If your document is in colors, the scanner will automatically scan the document
into a color image. If your document is non-color, you can choose the output to be either B&W
or Gray from the Non-Color Selection option. This option is useful when you have a mixture of
color and non-color document.
Note: If you choose Front Rear Auto Color Detection, you can not specify the image mode of
your rear page and vice versa.
Sensitivity of Auto Color Detection
If your documents contain primarily B&W text and a small amount of light or pale colors and you
do not wish them to be recognized as color image to save the file size, you can reduce the
sensitivity value by moving the bar to the left to let these images to be detected as B&W. The
value ranges from 1 to 100. The default is 37.
2.3.2 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.
Options: Dynamic Threshold, Fixed Processing, Halftone 1~5, Error
Diffusion.
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.
Sensitivity of Dynamic Threshold
Occasionally your scanned image may contain small dots or speckles. To
remove these spots, increase the sensitivity value by moving the bar to the
right. The value ranges from 1 to 30. The default is 20.
Fixed Processing: Used for black-and-white 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.
Halftone: In addition to the black and white display, Halftone can present a
somehow gray shade of image by using different size of dots. Halftone image
looks like the picture we have seen in the newspaper. Options include
Halftone 1, Halftone 2, Halftone 3, Halftone 4, Halftone 5.
Error Diffusion: Error Diffusion is a type of Halftone. Error Diffusion gives
good image texture and makes text in images more readable than Halftone.
Halftone Image Error Diffusion Image
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.
