Brightness
Brightness
means the black-and-white threshold of the image.
The brightness adjustment is by default
Automatic
.
You should
leave this default setting for all normal documents.
Manual
When dealing with bad quality documents, changing manually
the brightness level may level the quality of the black&white
image and so improve the text recognition.
To set the brightness manually, click
Manual
, then slide the
indicator to the left (lighten) or to the right (darken). If you
darken the image, more pixels become black in the black-and-
white image; if you lighten the image, less pixels become black.
Despeckle
The option
Despeckle
makes it possible to remove small spots
from the images. By default, the option is turned off.
To activate the despeckling, slide the indicator to the right. You
can remove dots from 1 to 20 pixels.
! Caution: Be careful not to erase spots that are too big,
otherwise you may start erasing the dots on the letter "i",
portions of dot matrix letters, etc.

set to function as current settings). When it comes to actually
