Option Description Settings Description of Settings
Scan Mode
For defining the type of image
processing to be used during
scanning.
B&W Threshold,
B&W Adaptive,
B&W Copy
Adaptive,
Graytone
24 bit Color
Default:
24 bit Color
 B&W Threshold - use thresholds to
determine whether a pixel is black or white.
Use this mode for drawings and line art. You
can set the threshold value (Level).
 B&W Adaptive - Suitable for scanning all
kinds of drawings including difficult
blueprints, brown transparencies (sepias),
etc. You set Adaptive level.
 B&W Copy Adaptive - enhancement on
foreground and background. This mode is
suitable for copying (scan and print) of
Sepia, Blueprint and other originals that
could be improved by clarifying foreground
and background.
 Graytone - 256 gray levels are recognized
for each pixel. Creates good reproductions
of complicated B/W images like B/W photos.
 24 bit Color - true color mode for capturing
all of the image's colors with the closest
reproduction. Produces large files. For
reproduction of complicated color images
like color photos and posters. You can make
tonal adjustments through a Gamma value.
Adjustment Options for the Scan Mode: The following 5 options are adjustment settings for the Scan Mode described above.
There is one adjustment setting option for each Scan Mode and so only one of the 5 options below will be displayed in the panel
and enabled for changing.
Level
(Active if Scan Mode
is set to B&W
Threshold)
For setting the threshold value
when the Scan Mode is B&W
Threshold.
0 – 255
Default: 151
When scanning at a specific threshold value, all
gray tones below the threshold will be
represented as black pixels, and all gray tones
above will be represented as white pixels.
Level
(Active if Scan Mode
is set to B&W
Adaptive)
For setting the amount of
adaptive processing when the
Scan Mode is B&W Adaptive.
0 – 255
Default: 0
The Level works like a threshold - the lower the
value, the more of the background is picked up
during scanning.
Level
(Active if Scan Mode
is set to B&W Copy
Adaptive)
For setting the amount of
adaptive processing when the
Scan Mode is B&W Copy
Adaptive.
Enables sharpen option (see
below)
0 – 255
Default: 0
The Level works like a threshold - the lower the
value, the more of the background is picked up
during scanning. Adaptive enhancement features
are automatically applied. You only have to adjust
the adaptive "Level" to determine the best degree
of enhancement processing for your specific
image.
Gamma
(Active if Scan Mode
is set to Graytone)
For tuning gray shades when
scanning to file in the Graytone
mode.
Enables sharpen option (see
below)
0.1 - 3.0
Default: 1.0
Pixels are intensified according to a gamma curve
they are mapped to. A low gamma value smaller
than 1.0 darkens the output while a high gamma
value larger than 1.0 typically lightens the shadow
areas and brings out detail.
