4 Image Processing Overview This chapter introduces concepts that may be new to many users. The
Kodak i30 and i40 Scanners provide the ability to process scanned
images to improve their quality. Using these features the scanner can
sometimes make the scanned image look better than the original
document. Basic image processing concepts are reviewed in this
chapter to help you take advantage of these powerful features.
Image processing refers to several separate features of the scanner
that allow you to automatically adjust each image in a certain way that
may improve the resulting images. Common examples of image
processing features are correcting any skew in the fed document,
cutting the edges of the image off to remove any unneeded border or
cleaning up extraneous “noise” on the image. The idea is to do this
automatically so you can get better images with a minimum amount of
rework.
The information that follows describes the image processing features
by walking you through the Scan Validation Tool. The same options
should be available on the user interface of the software application you
are using (i.e., Kodak Capture Software). All fields on the Scan
Validation Tool are described in this chapter.
Common terms Following are a few common terms that are used throughout this
chapter:
Bi-tonal or Binary — black-and-white.
Simplex — indicates that only one side of the document (the front side)
will be scanned, creating a single page image.
Duplex — indicates that both sides of the document will be scanned,
creating two page images.
Cameras — it is important to understand the concept of “cameras”.
The Kodak i30 Scanner is a simplex scanner. The camera has the
ability to separate color and bi-tonal/binary data simultaneously. This
means it scans one-sided documents; a front color camera and a front
bi-tonal/binary image, allowing you to capture one side of a document
either in color/grayscale or black-and-white with a single scan.
The Kodak i40 Scanner is a duplex scanner. The cameras have the
ability to separate color and bi-tonal/binary data simultaneously. This
means it scans both sides of a two-sided document; a front color
image, a rear color image, a front bi-tonal/binary image, and a rear bi-
tonal/binary image, allowing you to capture both sides of a document in
either color/grayscale, black-and-white, or a combination of color/
grayscale and black-and-white with a single scan.
When you use the Kodak Scan Validation Tool, you will need to select
which camera(s) you want to use to scan your document to get the
desired results. You can use the following examples as a guide when
making camera selections.
