Picture 20: DPI mode Flexible
DPI Mode
If the button DPI Mode is set to Flexible, the resolution can be selected out of a drop
down list right to the Resolution field.
This value can be manually overridden. Enter the desired resolution in the field left from
the drop down list field. The value can be varied in steps of 1 dpi. To send the new value
to the scanner, click on another menu item or press the “Tab” key or the “Enter” key on
your PC keyboard.
If the Resolution field value is changed, the right box will show user defined.
Brightness
The Brightness slider defines the brightness of the resulting image. Lower brightness
values make the image darker.
Contrast
The Contrast slider defines the contrast of the resulting image. Higher contrast values
show more details. If scanning in binary (i.e. Binary or Photo Mode), the behavior of the
contrast slider changes. If the Auto Threshold is off, the slider has no function at all. If
the Auto Threshold is on, the contrast slider defines the reaction time of the automatic
background tracker.
Note: Use the contrast slider carefully in the automatic threshold mode because if set to
the extremes, unexpected image artifacts occur.
