4.6.2.1.2. Gamma Correction
After activating Gamma Correction option, you
may adjust the brightness of a scanned image,
for all three color channels and for the greyscale channel.
The extended menu has
slide controls for each
of the three color chan-
nels
Red, Green,
and
Blue
(RGB), which default value
is 1.0 and can be increa-
sed to 5 in steps of 1/10th.
The activated option field
Combined
provides simul-
taneous adjustment of all
color channels as soon as
one of the three values is
changed. The brightness of the color channels is divided into 256 levels and influenced by the two
lower sliders of
Black Level
and
White Level.
Whilst the
Black Level
has a default value of 0 and brigh-
ten color tones are darkened by its increase, the White Level is 255 in default cases and provides the
brightening of darker color zones by its reduction.
4.6.2.1.3. White Background
Checking White Background will inform the
profile of the fact that the Scan Background has
been switched to white ( see chapter 5.5.1. ). As a result, the scanner’s document recognition and certain
other imaging functions will internally adapt themselves to the changed background color. Before
using this setting, you will have to deactivate Optimized Gap ( see chapter 4.6.4.2.8. ).
4.6.2.1.4. Add/Remove Borders
Use this menu item to add borders of specific
width, to all scanned images. Selected areas may
be removed from images,
by specifying negative
border values.
Switch Right and Left on
Back will automatically
swap the values for right
and left border size, on all
reverse sides of scanned
document sheets.
Tapping the Color button
in the center of the screen
will open a color picker dialog ( see chapter 4.2.2. ), which you can use to set the fill color for all border
areas added.
Please note!
When removing border areas, make sure to not truncate any image content.
