a normal type of illumination in the microscope for scanning
the slide. This option is recommended when scanning in Brightfield mode.

Thresholding
The manually specified value is used for thresholding during scanning. Preview image of
the loaded slide is displayed in the Preview window, and when modifying any of the
parameter values, it will have effect on the preview image. If the threshold value
presented on the Microscope Controller preview window is modified, this value is
automatically applied by the profile in the Profile Settings panel.
o
Specimen threshold
This value is definable manually: This sets the sensitivity of the specimen
detection. To set the desired threshold value manually, change the setting in the
Specimen threshold level
selection box in the range of 0-255. The default value is
220. Smaller values result in a more sensitive scanning, meaning that more areas
will be digitized, however, this may also include specks or other imperfections of
the slide. Greater values result in a less sensitive scanning, but it is possible that
some of the smaller specimen areas will not be digitized.
o
Auto Threshold
By clicking
the specimen will automatically be detected in the preview
image.
Caution!
Make sure that the detection result is acceptable for you. Otherwise, set the threshold value
manually or append missing areas with the help of appropriate functions in the
Preview
window.
