Microtek ScanWizard EZ Reference Manual 3
Scanning with the EZ Mode
This section provides the easiest and most basic scanning scenario with the EZ
mode of the ScanWizard EZ scanning software.
1. Place the material to be scanned on the scan bed.
2. Launch ScanWizard EZ (either as a stand-alone by clicking on the program
icon, or by using the File-Import or Scan command from an application
program).
3. Click the Scan button to start scanning.
The ScanWizard EZ will automatically detect the material on the scan bed
and calibrate the scanner first; then, crop the image, and at last carry out
the final scan with scanning settings. When the scan is done, the output
image can be saved in a file, delivered to the specified location or opened in
your chosen application.
• If ScanWizard EZ is launched from an application program, the
scanned image is delivered to your application, where the image can be
saved, printed, or modified further.
• If ScanWizard EZ is launched as a stand-alone program, the scanned
image can be saved as a file in your selected folder or opened in an
application program.

by default when ScanWizard EZ is launched for the first time. You may uncheck
the function by clicking the check box of each function in the panel.
Auto-crop
The Auto-crop function automatically detects the size of the original image,
crops the full scan frame to fit the image, and removes unwanted black borders.
It is disabled when the scan material is set as Negative or Positive Film in the
Scan Mode panel of the Advanced mode.

Nine Types of Image Effects
One major advanced feature offered by the ScanWizard EZ program is that the
system automatically provides a pre-screened parameter of image effects to scan
materials, which help you to exactly get what they see on the screen. It means
that no more fuzzy and tedious steps are required when you want to apply some
image effects to your scan materials. The nine types of image effects include the
followings:

Color Gray Line Art
Threshold
The Threshold control is active only when the Type setting is ”Line Art” and the
“Auto Threshold” is unchecked in the Advanced Settings window. The default
Threshold is preset to 127.
Uncheck the Auto Threshold to set up
To change the default Threshold
the Threshold manually
setting, you should disable the
“Auto Threshold” setting in the
Advanced Settings window. To do
this, click the Advanced... button
to open the Advanced Settings
window, uncheck “Auto
Threshold”, and click OK. Then
return to the control panel to drag
the slider, or enter a desired value
in the Threshold edit box.
Threshold is the dividing point between black and white; the range is 0 to 255,
and the default is 127. Thus, gray levels below the Threshold are converted to
black, while gray levels equal to or above the Threshold are converted to white,
resulting in a high-contrast, black-and-white representation of the image.
• To darken the original, drag the slider to the right or enter a value in the edit
box. This increases the Threshold value so that more pixels are turned to
black, resulting in a darker image.
• To lighten the original, drag the slider to the left or enter a value in the edit
box. This lowers the Threshold value so that more pixels are turned to
white, resulting in a lighter image.
Original Threshold: 50 Threshold: 200
Microtek ScanWizard EZ Reference Manual 27
Brightness/Contrast
The Brightness/Contrast feature lets you control the brightness and contrast
levels of the selected frame image.
Increasing the brightness makes all tones in the image lighter. Contrast, on the
other hand, is the range between the darkest and lightest shades in the image,
and increasing the contrast makes for greater separation between the darkest
and lightest areas of the image. Levels of brightness or contrast are from -100%
to 100%, where 0 means no brightness/contrast is applied.
Descreen
The Descreen feature lets you remove moiré
patterns from printed materials. Moirés occur when
you scan a screened original (mostly reflective or
previously printed material, such as pictures from a
newspaper or magazine). These patterns appear to
the naked eye like a series or grid of dots or as

Shades that are darker than the shadow then become black, and shades
lighter than the highlight become white. For example, if you set the

green and red filter options are available for you to choose.
