• Scan specimen with auto threshold – This automatically detects the specimen in
the preview image.
• Scan specimen with user set threshold – 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
35. 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.
• Scan area inside the marker – If the specimen cannot be identified as required for
digitization, (for example, weak contrast), it can help to encircle completely the
specimen with a black marker pen. You have to draw a full circle with the pen to
enable the detection. Marker pen detection will make specimen detection easier by
limiting the scanned area.
If this option is selected, only the area encircled with a marker pen will be scanned.
You can define the threshold level by changing the threshold value in the Marker
threshold level selection box in the range of 0-255.
This sets the sensitivity of the specimen detection inside the marker area. 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 35.
To scan everything within the marked area, check the Scan everything within
marked area selection box.
