If the specimen area is barely visible, it is possible that the software will
analyze that area as an empty one.

Focus Exposure Time
This function is used for defining time length used for determination of focus but is inactive
when using AxioCam and pco.edge 4.2 cameras.
Image corrections
Flat field correction
If this function is active the scanned slide compensates itself with a special method (light
intensity statistical data, not to modify the average intensity of the slide. Quantitative
measurements can be made on the slide.

Maximum exposure time – A limit value can be set to determine that the exposure
time cannot be longer than the time of focusing and calculation of exposure. This is
necessary because the exposure time would be too long when taking image of an
empty field of view. Default value is 2000 ms.
Skip empty field-of-views – By selecting this function the software decides on the
base of the focus channel whether there is a specimen in the given FOV, or not. If
the FOV is empty, it will not be scanned at all, but an empty field is created instead.
Note, that when selecting this option, the speed of scanning process is increased.
Caution!
Do not use multilayer mode on empty field-of-views – If selected, the multilayer
mode function will not run on the empty (not containing specimen) field of views.
Use stitching – By selecting this function, it enables seamless stitching of digitized
tiles.
Sharpening – image contrast is increased (the image may become noisier)
Note:
Do not use this option if you want to take quantitative measurements,
since it may minimally affect the results.
