o
Specimen threshold
–
Sets the sensitivity of the specimen detection. To set the
desired threshold value manually, click the
Auto
button first (as it is activated by
default), then change the setting in the
Specimen threshold
selection box in the
range of 0-255. The default value is 212. Click
Calc.
to calculate threshold for the
preview image. 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.
o
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. 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
Use marker with threshold
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
selection box in the range of 0-255. The default value is 105.
o
Everything within marker
–
To scan everything within the marked area, check the
Everything within marker
selection box.
Alternatively, click
in the preview window to activate this function.
