For Kodak i1440 Scanners only:
• Photo: the scanner will locate the photograph on the document and
return an image that contains just the photograph. If the scanner
finds more than one photograph on a document, one image is still
returned. The entire document is used to locate the photograph.
• Photo w/Region of Interest: this option is the same as Photo
(above) except that only a portion of the document (which is specified
on the Scan Area dialog box) will be used to locate the photograph.
• Long Paper: the scanner will split the document into separate
images based on the area you specify on the Scan Area dialog box. It
is suggested that you select an area that covers the entire width of
the document and a height around 11 inches (297 mm).
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.
• Adaptive Thresholding (ATP): separates the foreground
information in an image (i.e., text, graphics, lines, etc.) from the
background information (i.e., white or non-white paper background).
When using Adaptive Thresholding, Brightness and Contrast can be
adjusted.
Brightness — changes the amount of white in the color and grayscale
image. Use the slider to select a value from 0 to 255. The default is 90.
Contrast ⎯ adjusts the difference between black and white, thereby
making an image sharper or softer.
The difference between black and white is small with a low contrast
setting, so the image is softer. With a high contrast setting, the
difference between black and white is large, so the image is clearer.
Select a contrast value from -50 to 50. The default is 50.
