Use threshold
•
Scan specimen with auto threshold – This automatically detects the specimen in the preview
image.
Important!
Make sure that the detection result is acceptable for you. Otherwise set
the threshold value manually or append missing areas with the help of
Scanned function located at the preview toolbar. For more information see
section 4.3.4 Preview area scanned by preview camera – Preview Toolbar .
•
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 the marked
area selection box.
