Cropping  allows you to capture a portion of the document being scanned. All cropping options can be used with color/grayscale and black and white images. Front and Back cropping are independent, however, for dual stream scanning, color/grayscale and black and white cropping must be the same per side. Only one cropping option can be assigned per image. Select one of the following options: • Automatic: dynamically adjusts the cropping window for different document sizes based on the edges of the image. • Aggressive: eliminates any residual black border on any image edges. In order to achieve this, there is a possibility that a small amount of image data from the edge of the document may be lost. • Fixed to Transport: (used for batches of same-sized documents) allows you to define the area to be imaged. Fixed to Transport cropping is used in conjunction with paper size and page layout and assumes you are center-feeding your documents. If you are not using center feeding, you must select the Layout tab to define your scan area. See the section entitled "Layout tab" later in this chapter. • Relative to Document: (zone processing): (used for batches of same-sized documents) - zone processing is a floating fixed crop window (the zone) located relative to the upper left corner of a document. It allows you to select an area on the document to be delivered in either color/grayscale or black and white format (a separate window for both black and white and color/grayscale may be defined). Different parameters may be selected for both the front and back of the image. This option may be used in conjunction with Automatic cropping where a separate color/grayscale or black and white area to be saved is desired. It is useful in applications where a photograph, signature, embossment or seal appears in a consistent area for an application (you may want that small area in color/grayscale and the rest in black and white). To define a zone, select the Layout tab. Binarization - these options work on grayscale images and outputs a black and white electronic image. Their strength lies in the ability to separate the foreground information from the background information even when the background color or shading varies, and the foreground information varies in color quality and darkness. Different types of documents may be scanned using the same image processing parameters and results in excellent scanned images. • iThresholding: allows the scanner to dynamically evaluate each document to determine the optimal threshold value to produce the highest quality image. This allows scanning of mixed document sets with varying quality (i.e., faint text, shaded backgrounds, color backgrounds) to be scanned using a single setting thus reducing the need for document sorting. When using iThresholding, only Contrast can be adjusted. • Fixed Processing (FP): used for black and white and other high contrast documents. If Fixed Processing is selected, only Brightness can be adjusted. 86 A-61560 January 2007

Cropping
allows you to capture a portion of the document being
scanned. All cropping options can be used with color/grayscale and
black and white images. Front and Back cropping are independent,
however, for dual stream scanning, color/grayscale and black and white
cropping must be the same per side. Only one cropping option can be
assigned per image. Select one of the following options:
•
Automatic:
dynamically adjusts the cropping window for different
document sizes based on the edges of the image.
•
Aggressive:
eliminates any residual black border on any image
edges. In order to achieve this, there is a possibility that a small
amount of image data from the edge of the document may be lost.
•
Fixed to Transport:
(used for batches of same-sized documents)
allows you to define the area to be imaged. Fixed to Transport
cropping is used in conjunction with paper size and page layout and
assumes you are center-feeding your documents. If you are not using
center feeding, you must select the Layout tab to define your scan
area. See the section entitled “Layout tab” later in this chapter.
•
Relative to Document
: (zone processing): (used for batches of
same-sized documents) — zone processing is a floating fixed crop
window (the zone) located relative to the upper left corner of a
document. It allows you to select an area on the document to be
delivered in either color/grayscale or black and white format (a
separate window for both black and white and color/grayscale may
be defined). Different parameters may be selected for both the front
and back of the image.
This option may be used in conjunction with Automatic cropping
where a separate color/grayscale or black and white area to be
saved is desired. It is useful in applications where a photograph,
signature, embossment or seal appears in a consistent area for an
application (you may want that small area in color/grayscale and the
rest in black and white). To define a zone, select the Layout tab.
Binarization
— these
options work on grayscale images and outputs a
black and white electronic image. Their strength lies in the ability to
separate the foreground information from the background information
even when the background color or shading varies, and the foreground
information varies in color quality and darkness. Different types of
documents may be scanned using the same image processing
parameters and results in excellent scanned images.
•
iThresholding:
allows the scanner to dynamically evaluate each
document to determine the optimal threshold value to produce the
highest quality image. This allows scanning of mixed document sets
with varying quality (i.e., faint text, shaded backgrounds, color
backgrounds) to be scanned using a single setting thus reducing the
need for document sorting.
When using iThresholding, only Contrast
can be adjusted.
•
Fixed Processing (FP):
used for black and white and other high
contrast documents. If Fixed Processing is selected, only Brightness
can be adjusted.
