Manual threshold
Set value manually or calculate value by using the Calculate Threshold
be activated only when manual thresholding is selected). 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 212.
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.
Use marker with threshold
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.

Manual setting of Use marker with threshold
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 Threshold selection box in the range of 0-255. The default value is 212.
Everything within marker
Available only if Use marker with threshold function is activated. To scan everything within the
marked area, check the Scan everything within marker selection box.
