Brightness/Contrast; Descreen; Document Enhancement; Default Button - Microtek ScanWizard EZ Reference Manual

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
shown in the example below.
To set the screen for your needs, press the drop-down arrow next to the box
and choose one setting from a predefined list.
Auto Color Restoration
The Auto Color Restoration feature brings faded colors back to life and to their
near-original colors. This feature is active only when the Type setting is "Photo"
or "Gray".

Document Enhancement

The Document Enhancement feature enables you to bring out and improve
readability of text in a document that includes other elements such as pictures
or graphs. This feature is active only when the Type setting is "Line Art".

Default Button

The Default button cancels the changes you have made with the image
correction controls and restores all settings to their default values.
