➟
The scanning resolution changes accordingly.
Hint
Magnification and Resolution
Why does the image size change with the magnification? Let us answer this with an example using an “BJ (720 dpi)” output device. If you were to scan an image with this device setting and set the magnification factor to 50%, the scanning resolution will automatically change to 360 dpi. At this setting, the image will be scanned at a resolution of 360 dpi and the output device will convert this to 720 dpi, shrinking the size of the output in the process because it will only have half the data with which to fill the space.
Image size = 5"x5"

Click the up or down arrow to increase or decrease the setting.
Hint
The Relationship Between Data Volume and Scanning Resolution
The higher the magnification and scanning resolution settings, the greater the file size of scanned images. There are certain inconveniences associated with overly large data volume, such as the inability to fit a file on a single floppy disk and the risk of causing a temporary computer slowdown by overwhelming its processing capabilities. For example, if you scan a standard size photograph in the color mode, the amount of data varies according the resolution.

Setting the Scan Mode
When an image is scanned, it is read as a collection of “dots.” The scan mode that is selected determines how each of these dots is represented in the output. The following five scan modes are available.
Black and White
Expresses the image with dots of only two shades: black or white. Select Threshold to lighten or darken the entire image by setting the value by which dots are judged to be either black or white. Select this option for scanning photographs and text for printing in monochrome.
8-bit Grayscale
Expresses a dot in up to 256 shades of gray. Select this option for scanning black and white graphics and photographs.
12-bit Grayscale
Expresses a dot in up to 4,096 shades of gray. Select this option for exceptionally high quality grayscale images. However, the file will be approximately twice the size of an 8-bit Grayscale file.
24-bit Color
Expresses a dot with 8 bits for each primary color – red, green, and blue (RGB) – for a total of 24 bits. A dot can be expressed in up to 16.8 million distinct shades. Use this option for most color photographs.
36-bit Color
Expresses a dot with 12-bits for each primary color – red, green, and blue (RGB) – for a total of 36 bits. A dot can be expressed in up to 68.7 billion distinct shades.
However, the file will be approximately twice the size of a 24-bit Color file.
Hint
Scanning the same image in the three different scan modes produces different file sizes. By size, black and white mode requires the least disk space, followed in order by the grayscale and the color modes. Before scanning, check the data volume indicator on the control panel.
The numerator indicates the amount of disk space required for the scanned image while the denominator indicates the amount of disk space available. When the required space exceeds the available space, the scan button is unavailable.
25
25
S T E P 2
Procedure
Click the arrow beside Scan Mode.
Selecting the box opens the pop-up menu.
Select a scan mode from the pop-up menu.
Caution
• If you select 12-bit Grayscale or 36-bit Color for a software application that does not support these options, the system may hang up when you attempt to execute the scanning job with either selection. Before you use these settings, check the specifications to determine whether or not 12-bit Grayscale and
36-bit Color scanning is supported. Adobe Photoshop (Ver. 4.0 or higher) and
Photoshop LE supplied with this package support these modes.
• If you scan an image with a version of Photoshop compatible with 36-bit
Color, the image is scanned as a 16-bit Channel Mode image.

Verifying the Image before Scanning
S T E P 2
Before initiating the final scan, it is advisable to check the intended results with the
Browser function. The image in the browser window is more accurate than the one in the preview window, allowing you to verify the results more precisely before scanning.

Using the Histogram Feature to Adjust Image Contrast
The data comprising an image contains a variety of brightness settings ranging from shadows to highlights. These settings are represented in Plug-in Module CS-S by values ranging between 0 and 255. The difference in these values determines the image’s contrast. To show how much of the image data falls into each brightness setting,
Plug-in Module CS-S contains a histogram feature that shows this data distribution clearly. With the histogram you can adjust the level of shadows and highlights to achieve beautiful tones with the best possible contrast.
Hint
• You can enhance images with the histogram options only when the image has been previewed in the color or grayscale scan modes.
• You cannot enhance the image with the histogram when ColorSync TM is selected.
How to Interpret Histograms
You can select the entire image or specify an area for which a histogram will be generated. The height of the peaks of the histogram is directly related to the volume of data with the corresponding value.
Portion with
Highlights
Distribution of data with a bias toward highlights.
Portion with
Shadows
Distribution of data with a bias toward shadows.
Entire Image Distribution of data widely distributed between shadows and highlights.
How to Adjust Histograms
To change the contrast in an image, the distribution of data between shadows and highlights can be adjusted by dragging the shadow and highlight marks at the bottom of the histogram. All of the data lying to the outside (left) of the shadow mark is changed to a zero value and all of the data lying to the outside (right) of the highlight mark is changed to a 255 value. The examples below show adjustments to improve the
contrast. Use the [Auto] setting to adjust the histogram for most jobs (p. 42) . The

Brightness and Contrast Settings
You can adjust the image with two slide bars, one for contrast and one for brightness.
Use this method to adjust an image before scanning if it is slightly out of focus or too dark.
Hint
You cannot use this feature with the black and white scan mode or the 24-bit color scan mode when ColorSync TM is selected.
Contrast
Contrast is the difference between the lightest light and the darkest dark in the image. A high contrast setting creates a great difference between light and dark shades, and there is a very sharp distinction between light and dark areas of the image. A low contrast setting creates a small difference between light and dark shades, and the distinction between light and dark areas of the image are not as obvious.
Contrast = 128 (Normal) Contrast = 170 Contrast = 100
If the image appears slightly out of focus, increase the contrast setting to sharpen the image. If the contrast setting is too high, shadows will blacken and the highlights will wash out.
Brightness
Brightness is the overall lightness or darkness of an image without changing the contrast. Adjust the brightness setting to change the overall lightness or darkness of the entire image. If the brightness setting is too high, the highlights will wash out, and if too low, the shadows will blacken.
Brightness = 128 (Normal) Brightness = 190 Brightness = 80

Gamma Value Settings
By adjusting the gamma value, you can more closely match brightness of the displayed image to the printed image. Adjust this value if what you see on the screen is very different from your printout.
Hint
• You cannot use this feature with the black and white scan mode or with the
24-bit color scan mode when ColorSync TM is selected.
Matching the Gamma Value to the Display Characteristics
Not all screen displays reproduce color tones in exactly the same way, and this reproduction method is expressed as a gamma value from 1.4 to 2.2 and normally reproduces a slightly dark image.
In order to avoid this and reproduce an image that is faithful to the original, the gamma value must be adjusted in Plug-in Module CS-S. Plug-in Module CS-S can adjust the pre-set screen gamma value of 1.8, but if the screen has a gamma value other than 1.8 then the gamma value for that screen must be set.
Gamma value
Plug-in Module CS-S and the screen display have different gamma values. During a scanning job Plug-in Module CS-S receives the image read from the scanner as input and sends it to the parent application as output. The gamma value in this interval where Plug-in Module CS-S converts input to output is the Plug-in Module
CS-S gamma value.
On the other hand, the data received from Plug-in Module CS-S as input is sent to the screen display as output. The gamma value in this interval where the image input from Plug-in Module CS-S is converted to output for the screen display is the screen display gamma value.
Setting the screen display gamma value causes the scanner gamma value to be calibrated automatically as the inverse value. For example, if the screen display gamma value is set for 1.8, then the scanner gamma value is calibrated for 0.56
(the inverse of 1.8).
Hint
• Please read the documents shipped with your display or contact the manufacturer’s customer service department to obtain the correct gamma value for your particular display model.
• If you intend to adjust the color tone with ColorSync™, change the settings in the ColorSync™ System control panel (found within the Control Panels folder) and do not manually change the gamma value settings as described in the following pages.

Brightness Settings for Black & White Images (Threshold Value)
When the scan mode is set to black and white, the image brightness can be adjusted.
The threshold value setting determines whether a halftone will be expressed as a black or a white data point. The possible threshold values range between 0 and 255. Below a given threshold value, all data is converted to black. Likewise, all data with a value above the threshold is converted to white. Accordingly, higher threshold values produce darker images while lower threshold values result in brighter images.
Threshold Value = 128 (Standard) Threshold Value = 180 Threshold Value = 70
To Set the Threshold Value
When the scan mode is set to black and white, click the [Tone adjustment] button or pull down the Image menu and select [Tone adjustment].
Drag the slidebar left or right to adjust the threshold setting.
Click the up or down arrow to increase or decrease the entry in the text box, or enter the value (0~255) directly from the keyboard.
After adjusting the threshold value, you can save the setting to a file under a file name and load the file again whenever you want to use the setting.
To restore the threshold setting to its default value, click this [Reset] button.

Auto Tone Correction (ColorSync™)
If you scan an image in 24-bit color with ColorSync TM selected, you can adjust the color automatically. The ColorSync™ function automatically matches the tones produced and displayed by scanners, displays and color printers. Optimal color correction is achieved with ease without having to make adjustments with the histogram or other color correction functions.
Caution
• This feature is available only when the scan mode is set to 24-bit color, not for
36-bit color, grayscale, or black and white.
• More time is required to start the program and scan when the ColorSync™ function is activated.
Hint
• ColorSync™ responds differently to each computer according to the unique conditions affecting it (type of display used, etc.), which may cause differences even between computers of the same make and system version. The tone characteristics of an image scanned with ColorSync™ on one computer, therefore, may change when processed on another computer.
• Color correction using the histogram function and gamma value settings cannot be conducted when the ColorSync™ function is activated.
To Activate the ColorSync™ Function
Open the [Image] menu and select [ColorSync].
Color is adjusted automatically to the optimum settings. The automatic setting may require a few seconds to activate. When ColorSync TM is on, you will see it checked in the menu. To switch ColorSync TM off, open the [Image] menu and select it again to remove the check mark.

Scanning Techniques
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 grayscale 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 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.
• With OCR applications using black and white scan mode, more than 300 dpi is the recommended scan resolution.
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.

Glossary
Brightness
The amount of light in an image when it is scanned. Increasing the brightness setting makes the entire image lighter, and decreasing the brightness setting makes
the entire image darker. (p. 47)
Contrast
The degree of difference between the dark and light portions of a document being scanned. Raising the contrast of an image tends to sharpen it, lowering the contrast tends to blur it.
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
(256 3 =16.8 million)
Color (36-bit)
Expresses a dot with 12-bits for each primary color, red, green, and blue (RGB), for a total of 36-bits (12 bits x 3 colors = 36 bits). A dot can be expressed in up to 68.7
billion distinct shades (4,096 3 =68.7 billion)
Dot
The fundamental element of a letter, object or image. The number of dots per inch
(dpi) determines the resolution (or density) of a letter, object or image.
Gamma Correction
The process whereby variations in color tones from the output of monitors, printers and other output devices are made consistent with the source (input) document. In
Plug-in Module CS-S you can use the gamma value setting, or enter a gamma value directly, to set a value to match the gamma value for your monitor. Gamma values are expressed as numbers: 1 is the standard value, numbers lower than 1 brighten the output and numbers higher than one darken the output. A graph function, the tone curve (gamma curve), is also available in Plug-in Module CS-S to make adjustments to gamma values.
Gamma Curve
See the entry for Gamma Correction.
Grayscale (8-bit)
Expresses a dot in 256 shades of gray between white and black.
Grayscale (12-bit)
Expresses a dot in 4,096 shades of gray between white and black.

Image File
A computer file generated by scanning an image or by creating an image with an image editing software program, such as Photoshop ® . An image file is generally comprised of bitmap data, a collection of color information corresponding to each dot of an image. There are many formats for image files, including the TIFF, PICT and BMP formats.
Preview
See the entry for Scanning.
Resolution
An expression of the density of dots in an image file that indicates the extent of its granularity. Generally expressed as the number of dots per inch (dpi).
RGB
An acronym for the base colors red, green and blue used in varying combinations to reproduce the full spectrum of colors on monitors and other output devices.
These colors are often referred as the base or primary colors.
Scanner
A device which scans a physical image from paper or other media and converts it to digital data which can be read by a computer.
Scanning
The process of using a scanner to read an image electronically. Before the final scan, a preview scan is generally conducted. The preview scan encompasses the entire scope of the document glass area and only provides a general indication of the image that may differ from the final scan. The final scan is executed after specifying the area of the image to be scanned and various settings that determine how the scan is conducted.
Tone Curve
See the entry for Gamma Correction.
