PANNORAMIC® SCAN RX 1.0
•
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.
Image Correction settings
•
Use Flatfield 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. The following three
options can be selected from the drop-down list:
o
Intensity statistics – legacy compensation algorithm
o
Reduce intensity – pixel-level analyzation of the acquired image during which the
background of the image is reduced based on the comparison of the image
recorded by the camera and the compensation image.
o
Intensity equalization – pixel-level analyzation of the acquired image, a one-by-
one type image compensation method is applied.
•
Extended focus – Select the type of the extended focus algorithm used during scanning:
o
Legacy – uses original extended focus algorithm, it is recommended for wide-field
fluorescence scanning. Note, that this algorithm is optimized for scanning large
areas, so if the size of the area to be scanned is insufficient, the correction might
not be perfect.
o
Maxima – the final image is made up from all of the layers created, areas (pixel
groups) with the highest intensity are combined together.
o
AVG – an average of the layers is used for the final image.
o
Max-AVG – the final image is made up from all of the layers created, areas (pixel
groups) with higher intensity than the average are combined together.
Image settings
Choose one of the following predefined image formats (and a subsequent custom option) from
the Image Quality drop-down list:
•
Excellent (JPEG: 90)
•
Good (JPEG: 80)
