•
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.
Note
:
This step is recommended when using FL mode, as the application is
less capable of finding the specimen based on the specimen threshold
level.

Remove coverslip –
If selected, the edges of the coverslip are not detected as specimen to
be scanned.
