Software
Windows® 95, Windows® 98 or Windows NT® 4.0 is required to run the
ScanGear CS-S. It is also recommended that you install the latest available
Windows 95/98 or Windows NT 4.0 Service Pack.
About ScanGear CS-S
ScanGear CS-S has a number of powerful features that help you get the most
out of your scanner’s capabilities. Using ScanGear CS-S, you can preview an
image and make changes before the image is scanned and acquired by the
application you are using.
Feature List
The following list describes some of ScanGear CS-S’s features:
• Flexible, fully automatic image acquisition, and pre-scan image
manipulation prior to passing data to the image application
• Sophisticated, Windows-compliant user interface
• Full support of TWAIN 1.6 specifications

Installing ScanGear CS-S 4.3
Selecting ScanGear CS-S
ScanGear CS-S can be called from any TWAIN-compliant application, such as
an imaging or OCR application.
Because the TWAIN-compliant application may install older TWAIN files than
ScanGear CS-S’s, it is recommended that the application be installed first,
before ScanGear CS-S.
If you have installed other TWAIN drivers on your computer, you may select it
as your default TWAIN source by using the application’s ‘File/Acquire/Select
TWAIN_32 Source’ menu option or its equivalent. Once you have selected
ScanGear CS-S as your source, choosing the command to scan, such as ‘File/
Acquire’, or ‘File/Scan’ will automatically start ScanGear CS-S in the
application.
Removing ScanGear CS-S
If you need to remove ScanGear CS-S from your system, use the following
steps to make sure all files are removed from all locations. Refer to the Quick
Start Guide for instructions.
Now that your ScanGear CS-S is installed and your scanner is ready to run,
you can start scanning or read more about scanning techniques. ScanGear

About Scanning
Scanning is the process of converting an image into computer-usable
information that is, digitizing the image. Scanners and digital cameras are the
main examples of devices that have the technology to transfer an external
image to digital information that can be saved as a file, printed, faxed, or
otherwise manipulated on your computer.
Until the introduction of digital cameras, scanners were the usual means of
turning a photograph or other printed graphic into computer compatible
information. Digital cameras use a similar process. Instead of exposing the
image in its lens to photoreactive film, the shape, color and shading
information is translated to a computer file. ScanGear CS-S lets you
manipulate the digital information before the image is saved or sent to its
final destination.
Using ScanGear CS-S with an Application
ScanGear CS-S is an interface between the scanner hardware and an imaging
application on your computer. With ScanGear CS-S, you can scan images
directly into an application without any interaction, or you can preview the
image and make changes to the way the scan is performed that affect the
resulting image.
You can also scan printed text and, when the Text Enhanced feature is
enabled, help your optical character recognition (OCR) software to recognize
text more effectively.
The TWAIN Interface
ScanGear CS-S is TWAIN-compliant. TWAIN refers to the set of standards that
define how information should be passed from image acquisition devices such
as scanners to software imaging applications that have the ability to import
TWAIN-compliant scanned images.
A graphics application is a typical example of a program that supports TWAIN
drivers. When you have a TWAIN-compliant application, scanner, and scanner
driver, you can scan an image directly into that application.

You can choose to scan the image without changing the default scan settings,
or you can use ScanGear CS-S’s settings to preview and adjust a variety of
settings prior to scanning. ScanGear CS-S’s settings are also dependent on
your scanner’s capabilities and the capabilities of the imaging application you
are using.
Acquiring an Image
When an application receives a scanned image directly from a scan, it is
acquiring the image. Throughout this manual, you will see references to
to import the image from the scanner; so it is acquiring the image from the
scanner via ScanGear CS-S.
Features of the ScanGear CS-S Window
The main ScanGear CS-S window is used to preview, adjust, and scan images
when the acquiring software lets you preview the image before scanning. For
details on applications that do not open the ScanGear CS-S window, see
“Scanning in “Windowless” (UI-less) Mode.”

The Preview Area
The preview area lets you “prescan” an image before it is scanned and
acquired by the application. The preview shows how the scanned image will
look after you scan.
When an image is previewed, you can use the tools on the toolbar to select a
portion of the image to scan, rotate or resize the image, or view the image’s
appearance after you make changes to the scanning mode, tone, or other
settings. The horizontal and vertical rulers, selectable on the toolbar, let you

Quick Start to Scanning
Use these steps to get going with ScanGear CS-S quickly, with the installed
settings.
Note:
ScanGear CS-S does not launch unless the scanner’s AC
adapter is plugged in and recognized by Windows.
Preparing the Scanner
Before you start scanning, be sure the scanner is properly connected and the
AC adapter is plugged in before you turn on your PC. If you want to ensure
that the scanner is functioning correctly, run the Test Scanner from FB1200S
tab. See “Testing the Scanner” in Chapter 4, “Scanning Devices.”
Place the item to be scanned image side down, and position it squarely on the
platen.
Previewing an Image
The advantage of using ScanGear CS-S is that you can preview the image and
make changes before actually scanning. That way, you can make sure you are
getting the most out of your scanner’s capabilities and of your time spent
scanning and working with the image.
Some applications, (for example OCR applications) do not require the
ScanGear CS-S window to open before the scan starts. However, ScanGear
CS-S has settings such as Text Enhanced that automatically give you the best
available scan without previewing the image.
To preview an image:
1. Place the item to be scanned on the scanner.
2. You must select a source if you have not already done so. On the menu of
your imaging application, use the command that selects the data source.
On many imaging applications, the menu item looks similar to the
following picture:
In the Imaging application that is included in the Windows 95/98
Accessories, the command is “Select Scanner” on the File menu.

Now you are ready to acquire the image.
4. On the menu of your imaging application, select the command that begins
the scanning process. On some applications, this is “Acquire/Image;” in the
Imaging application included in Windows 95/98, it is “Scan New.”
Unless you are using ScanGear CS-S in “windowless” mode, the ScanGear
CS-S window appears.
Previewing starts automatically (Auto Preview is switched on at default
settings).
The ScanGear CS-S main window opens, scanning begins automatically,
and preview begins. When preview is finished, the preview image is
displayed in the Preview Area.
When Auto Preview is switched off in the basic settings, click the Preview
button to start image preview.

5. To change a default setting before you preview, click the appropriate
ScanGear CS-S settings tab and select the settings you need. For full
information on each setting, see “Specifying How the Image is Previewed,”
later in this chapter.
6. On the Main tab, make sure you set the scan mode and resolution. If you
want to change the mode after you preview - for example, to change from
Color to Grayscale - the preview image clears, the preview area reverts to
its default size, and you must preview the image again.
Note:
If necessary, you can cancel a preview or scan. During a
preview, the Preview button becomes a Cancel button. During
Calibration will automatically be performed before scanning.
7. To adjust the image in the preview area, do one or more of the following:
eliminate the white space and any other unwanted part of the image. If
you do not crop the image, the white space is included in the final
scan. For details, see “Cropping Part of an Image” later in this chapter.

• Use the Zoom tool to zoom in before you crop. See “Zooming In and
Out,” later in this chapter. You can also use the Width and Height text
boxes on the Main tab in conjunction with the Crop tool to make your
selection more precise. If you want the acquired image to be larger or
smaller than the current preview size, use the Scale setting to set a
different percentage. For more information about zooming and scan
resolution, see Chapter 5, “Scanning Techniques.”
• Adjust the Contrast/Brightness, Gamma, or other tone settings to
adjust the image tone. When you adjust tone settings, you see the
results immediately in the preview image. For more information, see
the section “Setting Image Tone” later in this chapter.

Where is the Scanned Image?
Once scanned, an image becomes one of the acquiring application’s open
files. When ScanGear CS-S is launched from a TWAIN-compliant program,
clicking the Scan button also saved the image in the format determined by
the application from which ScanGear CS-S was launched.
Scanning in “Windowless” (UI-less) Mode
Some applications use ScanGear CS-S without opening the ScanGear CS-S
window (the user interface, or UI). These applications include Pagis, Microsoft
MS Picture It!, and most OCR (Optical Character Recognition) software. If you
are using software that does not open the ScanGear CS-S window, you are
unable to use any of the features on the ScanGear CS-S window. However,
with some applications, you may be able to perform a “custom” scan that will
open the ScanGear CS-S window.
For applications that do not show the ScanGear CS-S window, ScanGear CS-S
automatically uses the settings determined by the application that will
perform the scan with optimal results. Follow the instructions in your
application to scan the images.

Cropping Part of an Image
Click Crop and drag diagonally across an area of the image in the Preview
window to select that area. The area you select is outlined with a broken line.
You can adjust the crop lines once you have selected an area. If you hold the
cursor over the selection handle in the middle of a crop line, a two-headed
arrow appears. You can drag the line in or out to adjust the width and height
of the image.
Click outside the broken line to crop a different area.
• If you crop too small an area, the size resets.
• If you type new values in the Width and Height text boxes, the selected
preview area changes. If the Keep Proportions button is turned on
when you select a new area (you see a chain between the Width and
Height boxes), the proportions match the last locked proportion.
• The minimum scan width and height varies depending upon the scan
resolution selected. For example, at 75 dpi, the minimum width and
height is 9 pixels for a preview scan. At 300 dpi, the minimum width
and height is 35 pixels for a preview scan.
Note:
If your mouse has left-handed settings, the right and left
mouse settings for ScanGear CS-S tools are reversed.
Moving an Image
The Move Image tool lets you move a zoomed image in the preview area.
Click Move Image and drag the zoomed image around to display hidden parts
of the zoomed image.
Zooming In and Out
Click Zoom to enlarge the image in the preview area. Click once to enlarge
the zoomed image 2x. The maximum enlargement is 16x. Right-click the
image once to zoom out and reduce the enlarged image 2x per mouse click.
Creating a Negative Image
Use the Negative/Positive tool to create a negative image of the original. A
negative image is created by converting the colors in the image to their
complementary colors - the opposite color on the color wheel. Clicking a
second time makes a negative image of the negative image, thus returning
the image to the original positive image.

Specifying How the Image is Previewed
Before you scan or preview, you can change the mode and specify how the
image appears in the acquiring application.
To specify how the image is previewed:
1. Choose the Scan Mode that best matches how you want the scan of the
object to be output.
Note:
If you have already scanned an image and then change the
scan mode, the image is cleared from the preview area, and
you lose your preview image and all the settings you have
made.
2. Specify the Scan Resolution that best matches how you will be using the
scanned image.
3. Specify Width and Height of the platen area to be scanned if you want an
area other than the full platen scanned. Specify Units if other than the
default.
To keep the width to height ratio (proportion), click the Keep Proportions
button before changing the width or height values.
4. Change the Scale from 100 percent to either enlarge or reduce the
scanned image. The new Output size (width and height times the scale
factor) is displayed to the right of the Scale text box. To set the scale,
either click the up or down arrows or click in the field and type a
percentage.

Setting Scan Mode, Resolution, and Dimensions
When ScanGear CS-S is installed, the settings are in place and you can scan
without changing them. However, there are a wide variety of options available
for you to change the look of the preview and scanned image. You can
change the settings at any time and preview the results. Repeat this process
until you are ready to complete the scan. Some changes (Tone tab settings
and output size) take effect immediately and can be seen on the preview
image; some changes (changing the scan mode) require that you click the
Preview button again.
The primary settings for image acquisition, including scanning mode,
resolution and scanning area, are on the Main tab.
Setting Scanning Mode
The scanning mode-Black and White-affects the settings on all the other tabs.
The icon to the left of the list box reflects the current selection.

To set scanning mode:
1. Click the Main tab.
2. Select an option from the Scan Mode list. You have the following choices:
• Color (36 bit): 36 bit color images contain 12 bits per pixel for each
primary color (red, green, blue). Use this option to attain a scanned
color image of the highest quality. However, the file will be
approximately twice the size of a Color (24 bit) file.
• Color (24 bit): 24 bit color images contain 8 bits per pixel for each
primary color. Use this option to attain a scanned color image of
average quality.
• Grayscale (12 bit): 12 bit grayscale images contain 12 bits per pixel.
Use this option to attain a scanned grayscale image of the highest
quality. However, the file will be approximately twice the size of a
Grayscale (8 bit) file.
• Grayscale (8 bit): 8 bit grayscale images contain 8 bits per pixel. Use
this option to attain a grayscale image of average quality.
• Black and White: Images are expressed in two colors only; black or
white. A pixel is set to black or white depending on its brightness value
in relation to a particular threshold value. The threshold value can be
freely set. Select this option to print photographs on monochrome
printers.
• Text Enhanced: Text Enhanced images are Grayscale images (8 bits per
pixel) converted to Black and White (1 bit per pixel) using Canon
ImageTrust technology. You can select Text Enhanced in the Scan
Mode list. If the application operates in windowless (UI-less) mode, you
can select “Text Enhanced” in the Preferences tab, and request the
application to perform a Black and White scan. In this case, the
conversion to Black and White takes place automatically.
The acquiring application may determine your Scan Mode choice. For
example, if a fax application is acquiring the image, you may not be able to
choose a color mode; you may have to choose Black and White or Grayscale.
The 24 bit and 36 bit options express colors with conversions of each primary
RGB color (Red, Green, Blue). The 24 bit options can express each color with
up to 256 gradations, and 36 bit color with up to 4,096 gradations. If you
need extremely high-quality color gradation in the scanned image, use 36 bit
color. Otherwise, use 24 bit for normal color scanning jobs.

The Grayscale options express varying shades of gray between white and
black. The Grayscale (8 bit) option can express shades within a range of 256
gradations and the Grayscale (12 bit) option within a range of 4,096
gradations.
Note:
If you attempt to use the Color (36 bit) or Grayscale (12 bit)
options to scan an image with a software application that
does not support these options, the system may hang up.
Before you use either 36 bit or 12 bit grayscale, check the
specifications of the parent software application to confirm
whether these options can be used. You can use Color (36 bit)
and Grayscale (12 bit) with Photoshop Ver. 4.0 or later and
with Photoshop LE enclosed with this package.
If you scan an image with a version of Photoshop compatible with 36 bit color
and 12 bit grayscale, the image is scanned as a 16 bit Channel Mode image.
Selecting Scan Resolution
Using the Scan Resolution list, you can select the resolution of a scanned
image based on the selected output device. This resolution becomes the base
on which changes to image size and scale are calculated.
The resolution you choose depends on the limits of the printer or other
output device. However, you can also select a custom resolution and make
more specific resolution choices.
Note:
The maximum resolution of the scanner is set at 600 dpi when
the optional automatic document feeder (ADF) is installed.
Selecting a Preset Resolution
The list of preset resolutions should cover most of your scanning needs.
Available resolution settings depend on the capabilities of the acquiring
application.
To select a preset scan resolution:
Select an option from the Scan Resolution list.
Depending on your selected device, you have different resolution choices. For
example, if the acquiring application is configured to print the image, your
choices may be limited to the printer’s maximum resolution.

Setting Units of Measurement
In the Units list, you specify the unit of measure for width and height of the
scanned image. The preset unit of measurement is based on the
Measurement System setting of the Regional Settings in your Windows
Control Panel.
To set units of measurement, select inches, centimeters, or pixels in the Units
list. The Width and Height values display in the units you choose.
There is no change to the size of the selection rectangle in the preview area
when units of measurement are changed, but the horizontal and vertical
rulers reflect the currently selected measurement units. For example if you
select centimeters, the default Width value of 8.49 inches changes to 21.57
centimeters.
Setting Image Width and Height
The Width and Height text boxes contain the width and height of the current
selection or, if there is no selection, the maximum output size, measured from
the upper left of the image in the preview area and based on the currently
selected paper size.
The width and height values change when you select part of the image in the
preview area. Correspondingly, when you change the amounts in the Width
and Height boxes, the selection borders in the preview area change to match.
To change size without constraint, do one of the following:
• Click the Crop button on the toolbar and select a section of the image
in the preview area. The measurements in the Width and Height text
boxes display the new sizes.
• Type the desired measurements in the Width and Height text boxes.
The image selection borders change to match the width and height you
enter.
Maintaining Image Proportion

When you click the Keep Proportions button, the image size is maintained in
the same proportion whenever you change either the width or the height.
Keep Proportions active
For example, if you set the width to 4 inches and the height to 6 inches, and
then you change the width to 5 inches, the height stays at 6 inches if the
constraint is turned off, so the proportion of the image width and height
changes. If you click the Keep Proportions button and then change the width,
the height automatically changes to 7.20 inches.
When the Keep Proportions button is selected, the image maintains the same
ratio indicated in the Width and Height text boxes.
To change size proportionally:
1. Click the Keep Proportions button.
A chain appears between the Width and Height text boxes.
2. Click the Crop button on the toolbar and select part of the image in the
preview area.
When you enlarge or reduce the selection, notice that the image width
and height stay in the same proportion.
Setting Scale
The Scale setting lets you specify an output size for the selected image as a
percentage of the original width and height. The scale amount is preset to
100 percent.
If you reduce the scale of an image that has a width of 7 inches and a height
of 9 inches by 50 percent, the selection in the preview area and the values in
the Width and Height text boxes remain the same, but the Output size
changes to indicate the size of the image when it is acquired by the
application. For example, if your preview image is 7 inches wide by 9 inches
high, and you select a scale of 50 percent, the output image will be 3.5 inches
wide by 4.5 inches high.

Hints for Editing Custom Tone Curves
You can choose a channel and begin to edit the custom curve with the
automatic curves as a starting point. Keep the following in mind when editing
a custom curve:
• The curve box handles are drawn on a white background to signify
that they are editable.
• The curve end points can be selected and dragged to any point in
the curve.
• You may add points to the curve by clicking anywhere in the curve
box.
• If a point is dragged outside of the curve box, it is deleted from the
curve and a new curve is fit to the remaining points.
• The x and y axes on the curve chart represent the input image color
and output image color. When you add a handle to the curve and
drag that handle toward the white areas, the preview image tones
are adjusted to reflect the change.
• You cannot position two handles on a vertical line, because you
cannot have two of the same x values due to the mathematical
formulas involved in drawing the curves. However, you can have
two or more of the same y values, so you can have several handles
on a horizontal line.
• The least and greatest x values for end points, whether original or
added, cannot be deleted.

About Canon ColorGear Color Matching
Canon ColorGear Color Matching is the universal color-matching system for
Canon printers, copiers, and scanners that makes predictable color available
for all levels of users, from home user to professional publisher.
Canon ColorGear Color Matching provides RGB to CYMK conversions that
are optimized for Canon scanners, printers, and copiers. Canon ColorGear
Color Matching also enhances and optimizes the monitors of most other
manufacturers.
With some printers, there is a discrepancy between the color image displayed
on a computer monitor and the same image printed on a color printer. The
color printout is disappointing because the colors are duller, or the color does
not match the color on the screen. Canon ColorGear Color Matching ensures
that this does not happen.
Canon ColorGear Color Matching is compliant with ICC (International Color
Consortium) guidelines. ICC is a group of hardware and software companies
which developed cross-platform, industry-standard guidelines for color
devices. Canon ColorGear Color Matching is also compatible with the ICM
(Image Color Matching) component of Windows 95/98/NT.

Threshold Setting
The Threshold slider can be used to adjust the threshold value (the
demarcation between black and white) of black and white images. Images are
collection of data assigned varying brightness values. Grayscale and Color
images express the brightness with 8 or 12 bit values whereas Black and
White images express the brightness with only two values, black (0) and white
(255). Accordingly, a point has to be determined either black or white. This
point is called the threshold value. By changing the threshold value, you can
alter the appearance of image. The default setting is 128.
To adjust threshold value, drag the slider or input the value directly into the
box (click the box and type the number from 0 to 255) in FB1200S tab.
Descreen
Moiré patterns occasionally appear when items printed at high resolutions are
scanned. To reduce this phenomenon, scan photographs and other high-
resolution prints with the descreen activated. Deactivate descreen to scan
lower resolution items, such as newspapers, books and magazine text.
• The Descreen is unavailable when the scanning resolution is set for 601
dpi or more.
• Descreen returns to the previous setting when a scanning job is started
with a parent software application that cannot display the ScanGear
CS-S operation panel.

About Scanning Techniques
This chapter provides additional information about scanning theory and
practice. It has basic information to help get the most out of ScanGear CS-S’s
tools, and to help you make the right choices before scanning your images.
Using the information in this chapter in conjunction with the information in
Chapter 3, “Scanning,” should let you produce effective results from your
scans.
Planning for the End Result
The settings you use to scan depend on the purpose of the scan. Will the
result be printed on a color printer, be included in an Internet web site, or be
used for professional color magazine printing? Is an OCR application acquiring
the scanned image for conversion to text? All these target destinations have
different requirements for color mode, resolution, and tone.
Preparing the Material to Scan
A general rule of image reproduction is that the output image can be only as
good as the original. Anything you can do to lessen the manipulation
between the original and the end result will give you a better quality product.
If the original image needs correction - for example, it is overexposed,
underexposed, or blurry - more time will be needed to make the correction,
and the results may still be limited by the flaws of the original image.
ScanGear CS-S lets you correct many undesirable features in scanned images,
but you will save time and effort by starting with the best possible original
image.
• Although ScanGear CS-S’s Tone tab lets you adjust for over- and
underexposed images and other tone problems, it cannot bring a
blurry image into focus, and “sharpen” options in the imaging
software can only do so much with a blurry original. If you are
scanning a photograph or other reproduced image, make sure the
original is in the sharpest possible focus or delineation.
• If you are scanning text, make sure the print is clearly defined.

Scanning Techniques
• Although it may seem obvious, it is important to line up the original
as straight as possible so you do not have to make adjustments in
the scan.
• If you plan to rotate the image in the ScanGear CS-S preview
window or in the acquiring software, try positioning the image so it
is already rotated before the scan.
Matching Scan Resolution to Purpose
ScanGear CS-S provides many choices for resolution. What resolution you
choose depends on your output device, how you want to use the image, the
type of image, and your scanner.
In general, it is recommended that you scan the image at a higher resolution
than you need. That way, you retain the amount of information in the image,
and if necessary you can reduce the resolution in the imaging application,
after the image has been scanned and acquired.
Different types of images need different types of scan settings. However, after
a certain point, increases in scan resolution will not improve the output image
quality. For example, a text image can be scanned at 600 dpi for output to a
600 dpi laser printer, but a color image should be scanned at 180 dpi to be
output to a color BJ-printer. When the image is output to a Bubble jet printer
in the color or gray mode, for example, the basic resolution of the printer is
halved. For example, for a 360 dpi printer the basic resolution is set for 180
dpi.
• If your image is black and white with no shades of gray, such as line
art, scan in Black and White mode.
• If you are scanning a text image for conversion to a text file, scan in
Text Enhanced mode.
• If you are scanning continuous-tone black and white photographs,
charcoal drawings, or any original with shades of gray, scan in
Grayscale mode.
• For full-color images, such as photographs or illustrations, scan in
Color mode.
• For example, with OCR applications using Black and White scan
mode, more than 300 dpi is the recommended scan resolution.

Scanning Techniques
Optical and Enhanced Resolutions
Optical resolution refers to the amount of information a scanner can sample
per inch. Different varieties of scanner feature different optical resolutions.
The maximum optical resolution of the CanoScan FB1200S is 1200 dpi for
both the primary scan (horizontal dimension of the document) and secondary
scan (vertical dimension).
The 1200 dpi resolution of the primary scan is achieved with a proprietary
Canon technology, the VAriable Refraction Optical System (VAROS). VAROS is
a two-pass scanning technique that combines the results of the scanning
unit's first pass with a second pass that is optically shifted by a half pixel. This
technique is used for scans at resolutions of 601 dpi or greater.
Estimating Image Sizes
When scanning many files, you have to consider the available space on your
hard disk and weigh it against how you plan to use the images.
High - resolution, color image files take longer to scan. If you have less than
32 MB of RAM, working with large color image will be very time consuming.
Consult your imaging application’s documentation for guidelines.
The output file size depends on the image resolution, scan mode (Color, Text
Enhanced, Grayscale, or Black and White), and output dimensions. Lower
resolutions contain a fewer number of dots per inch, and therefore less digital
information to store on disk. So, when estimating the size of an image, you
have to include the output file size, the resolution, and the number of colors.
Resolution and Color
The greatest amount of disk space is required for a 36 bit Color image of one
horizontal inch, centimeter, or pixel. Each pixel contains 24 bits of color
information: 8 bits each of red, green, and blue, and 36 bits of color
information are required for a 36 bit Color image. Resolution refers to the
number of pixels per inch, or in printing terms, dots per inch (dpi).
Check the ScanGear CS-S status area for the estimated file size of the acquired
image. Generally, file sizes can range from 15 KB for a 6 inches x 4 inches image
scanned in Black and White mode at 75 dpi to 202,500KB (198 MB) for the same 6
inches x 4 inches image scanned in 36 bit Color mode at 1200 dpi.

Cropping the Image Shape
In most cases, you will want to crop the preview image before your final scan,
to eliminate white space or other unwanted images from the final product. By
combining the use of the Crop and Zoom tools, you can easily select a precise
section of the image, and then make other changes.
The Crop tool lets you select a rectangle shape of the preview image. You can
switch between the Crop tool and the Zoom tool to select exactly the part of
the image you want acquired.
If you select pixels as the unit of measure, you can see the exact size of your
selection on the rulers in the preview area.

To zoom and crop the preview image:
1. Preview the image as described in Chapter 3, “Scanning.”
2. With the Crop tool, select part of the image. The selection is outlined with
a broken line. Handles appear at the corners and midpoints of the
selection rectangle, and the cursor changes to a selection
crosshair.
You can move the entire selection rectangle around, or you can adjust any
edge or corner of the rectangle by moving one of its handles. When you
place the cursor over a handle, it turns to a double-headed arrow, and you
can drag that side in, out, up, or down to increase or decrease the
selection rectangle more precisely.

3. Click the Zoom tool and zoom in on the image. When you select the Zoom
tool, the cursor changes to a magnifying glass.
The plus and minus signs on the mouse indicate that you can
enlarge the image (zoom in) by clicking the left mouse button,
and zoom out by clicking the right mouse button.
By zooming in on the image even more, you can select a more precise part
of the image to scan or work with.
4. Continue alternating between the selection and other tools on the
ScanGear CS-S toolbar as long as you do not click off the selection with
the Crop tool.
Custom Tone Adjustments
The settings on the Tone tab let you make individual adjustments to a variety
of tone settings.
What Do Those Curves Mean?
The curve displayed on the Tone tab represents the values of the preview
image according to the tone tool you are using. You may see multiple curves
of red, blue, and green, depending on the settings on the Tone tab, the color
mode, and the image.
The shape of the curve changes to reflect the current settings of the
Automatic, Contrast/Brightness, Gamma, and Histogram tone tools. You
cannot edit the curve except with the Special Tone Curves tool.
Contrast and Brightness Adjustments
The Contrast/Brightness tools control use the image’s brightest and darkest
tones for its reference in adjusting the overall image in a uniform way.
If you increase an image’s brightness by 10 percent, even the bright parts are
increased by 10 percent. So, if you are scanning an overly dark image with a
wide range of tones, increasing the brightness makes the dark tones more
visible, but the brighter parts may appear faded and washed out.
The contrast control bases its calculations on the image’s dark and light tones
to calculate an overall adjustment. Because the adjustment affects the lightest
and darkest tones, increasing the contrast increases the proportion of bright
and dark tones in the entire image. Decreasing the contrast lessens the
proportion of bright and dark tones in the entire image. This can give the
image a dull, washed-out look.

Scanning Techniques
If you have a high-contrast image, or a black and white continuous tone
photograph that needs minor adjustment, the brightness and contrast
settings can improve the image.
If you have an image with multiple tones, such as most color images, the
brightness and contrast settings may not provide the desired results. The
Gamma, Histogram, and Special Tone Curves, which let you adjust the
midtone range and contrast as well as individual color ranges, may give you
more satisfying results.
Gamma Adjustments
The Gamma curve tool adjusts the midtones in an image in relation to
themselves. Adjusting the gamma setting can improve the visibility of color
and grayscale images, particularly ones with many midtones. Gamma values
above 1.00 lighten the midtones of an image, and values below 1.00 darken
the midtones. The gamma settings can range from 0.10 and 10.00, but for
most color photographs, the range is between 1.00 and 2.00. The
photographs scanned for the illustrations in this manual had many dark
midtones in the background, so a lower setting was used to enhance the
background.
Histogram Techniques
The histogram displays a graph of all the pixels in the image, sorted by tone.
The darkest pixels are grouped to the left, the midtone pixels in the middle,
and lightest tone pixels to the right. The triangular sliders at the bottom of the
histogram reflect the default settings of Black-Point 0, Mid-point 128, and
White-point 255.
The histogram tools let you change the distribution of dark-tone, midtone,
and white-tone pixels in your image, to correct the image. Any changes you
make are immediately displayed in the preview image.

The following preview image has too dark a background, probably because
the photograph was exposed to set off the white flowers more effectively.
The histogram for this image shows that most of the pixels are between the
black and gray points, so there are too many dark pixels in the image. The
diagonal line indicates the color channel, in this case, the Master channel.
The following figure shows just the histogram of the same image, but with
the blue channel, the predominant color in the image, selected. Notice that
the blue pixels are more evenly spread around the midtones, but there is still a
large distribution of pixels in the dark-tone area.

The following figure displays the histogram when the flower is cropped.
Notice the pixels are spread more evenly, although still leaning to the darker
side of the midtones.
You can adjust the histogram so the pixels are spread move evenly throughout
the range of tones in the image. The procedures for adjusting the histogram
are in “Change Tone Using the Histogram Tool” in Chapter 3, “Scanning.”
The easiest way to affect the redistribution of pixels is to adjust the triangles
at the bottom of the histogram. When you move the Mid-point slider to the
left, a larger number of pixels fall into the midpoint range, and more midtone
shades become visible.
Move the triangles to

You can also achieve some special effects by manipulating the black-point,
mid-point, and white-point values to the extreme. In the following figure, the
Mid-point has been moved to the right of the White-point, producing a
solarizing effect to the lighter areas of the image.
Although the Special Tone Curves provide the best facility for manipulating an
image for special effects, you can experiment with any of the tone tools.
Sampling a Tone for the Histogram
To sample a tone for the histogram, zoom in as close as possible and sample
the black point, midpoint, and white point from an enlarged section, to make
sure you are sampling the shading you want. This is especially important
when you are adjusting an image with many dark tones and midtones, and it
may be difficult to determine the darkest or brightest spot with the naked
eye.
If necessary, select a section from which to sample, and re-preview the image,
then select the sample.
To sample a tone for the Histogram:
1. Zoom in on the area of the image from which you want to take a sample.
2. Using the Crop tool, select an area of the zoomed-in image from which to
take the sample.
3. Click Preview to re-preview the image. The preview image displays only the
selected, enlarged area.
4. On the Tone tab, select the Eyedropper tool for the Black-point, Mid-point,
or White-point values.

5. Click the Eyedropper tool on the point of the image you want to sample.
That value is entered in the corresponding text box, and the image adjusts
according to that value.
6. If the area of the image surrounding the sampled area changes tone as
you expected, make a note of the settings. If the selected image area does
not change tone as you expected, repeat this process until you get the
results you want.
Enhancing Color Images
This is a brief discussion about color basics. There are many good books about
working with graphic images. If you are using color imaging software such as
Adobe Photoshop LE, your software documentation can provide you with
more information to help you adjust your images when they have been
scanned and acquired by the imaging software.
About Image Color and Color Channels
All printable colors can be created using a combination of the colors cyan,
magenta, and yellow (CMY). (Black is often used in printing, so you may hear
that colors are printed using the “colors” CMYK, the K stands for “Key
color.”)
All colors displayed on monitors can be created using a combination of the
colors red, green, and blue (RGB). Red, green, and blue can be thought of as
complementary colors to cyan, magenta, and yellow-that is, the colors cancel
each other out when combined in equal amounts. Similarly, adding a small
amount of one color reduces its complement by that amount.
This complementary relationship between the colors cyan, magenta, and
yellow and the colors red, green, and blue can be represented using a color
wheel that indicates the possible colors and their opposites.

Using this color wheel model, you can use the Tone tab adjustments to modify
specific colors and correct the preview image before scanning. You can select
the Red, Green, or Blue channels and adjust the Gamma, Custom Curve, and
Histogram settings for the image, to provide the results you want.
For example, if your original picture has too much yellow, you can adjust the
color by increasing its complement (more blue). If the image has too much
green, you can increase the combination of colors to decrease the magenta.
Note:
If you are working with images that are meant for
professional color printing, all your equipment should be
calibrated so the color values on your scanner, monitor, and
output devices are using the same frame of reference. This
means you should make sure you have a video monitor that
can display Full Color (24 bit), up to 16.7 million colors.

Pre-Scan Checklist
Before you begin troubleshooting specific problems, verify that you have
reviewed this checklist.
• Viewing that your system meets all the memory, hard disk and
operating system requirements listed “System Requirements” in
Chapter 1.
• Make sure that the ScanGear CS-S software was installed
successfully.
• Check that the cables between your computer and scanner are
connected securely.
• If you see a message on the screen that says something like this:
“Device failed/cannot find TWAIN...” make sure you have connected
the AC adapter first, before your PC. If necessary, turn the scanner
off and back on again.
• Connect the AC adapter to your scanner before you turn on the
computer.
• Before scanning or previewing, check that the data source has been
selected. If your scanner does not appear as an option when you
select a source to scan from your imaging software, you may have
to install ScanGear CS-S again.

Frequently Asked Questions
“Top Ten” List
Here is a list of the “Top Ten” pieces of advice for scanning.
1. Start with the best possible original image to scan.
2. Select only the part of the image you want to scan. Preview the image and
select it. Not only does a more precise selection save file space, but your
image quality will be much higher.
3. Check the output file size before beginning the scan. Make sure you have
enough room if you are scanning files that take up a lot of disk space.
4. Match your Scan Mode to the output purpose. If you are scanning text,
use the Text Enhanced mode. If you are scanning line art, use the Black
and White setting, and so on.
5. Match your scan resolution to the type of file you need. If you are
scanning images for use as .GIF or .JPG files on the Web, you do not have
to scan at 600 dpi. Although it is recommended that you scan at a higher
resolution than you need for high-quality color images, you should balance
that factor against your planned use for the image.
6. Take advantage of the Gamma tone curve and other tone tools to correct
your images.
7. Try to use Full Color mode on your monitor so you can view your preview
image as accurately as possible.
8. If you are using OCR software, scan in Text Enhanced at 300 dpi or higher.
9. If creating halftones, scan at twice the halftone resolution.
10.Take advantage of the preview feature and preview as much as you want
before scanning.

Frequently Asked Questions
Printing or scanning is too slow.
Problem:
The printer or scanner is taking an unusually long time to
print or scan.
Cause:
The selected output resolution of the image may be too
high for the resolution of your printer, or your computer
may be low on memory.
Solution:
Before printing the image, make sure you have set the
scan resolution (on the Main tab) to not exceed the
resolution of your printer. Also check to see if there is
enough memory available in your computer. Before
printing, quit other applications that are not in use.
Parts of images are missing or misaligned.

Grayscale (12 bit)
Expresses a dot in 4,096 shades of gray between white and black.
Color (24 bit)
Expresses a dot with 8 bits for each primary color for a total of 24 bits (8 bits x
3 colors=24 bits). A dot can be expressed in up to 16.8 million distinct
shades(2563=16.8 million)
High Quality Color (36 bit)

Brightness
The overall amount of lightness or darkness in an image. An image with
maximum brightness tends toward white; an image with minimum brightness
tends toward black. While contrast refers to the range and number of tones
in an image, brightness refers to the intensity of tones.
Canon ColorGear Color Matching

CMYK
An acronym for cyan, magenta, yellow, and black, the four-color process used
in most commercial printing. (The black “K” stands for “Key color.”)
Color Channels
The red, green, or blue components of a color image. Color images contain 8
bits/12 bits per pixel each for red, green, and blue channels, therefore each
pixel has 24 bits/36 bits. If you are scanning a color image, you can change
the brightness and contrast of the individual red, green, and blue tones in
your image. The Master channel is a combination of the three.
Color Matching
The range of colors your scanner can see may not match the range of colors
your video monitor can produce. Color matching lets your system display
colors so that the color on your monitor and printer matches the colors
scanned. See also Canon ColorGearTM Color Matching.

Color Wheel
A representation of colors and their complements.
Complementary Colors
Red, green, and blue can be thought of as complementary colors to cyan,
magenta, and yellow. These colors cancel each other out when combined in
equal amounts. Similarly, adding a small amount of one color reduces its
complement by that amount.
