4.4 Operation of camera functions
The system is equipped with a very reliable and convenient automatic focus system. This auto-
matically performs an auto-focus adjustment with each zoom operation. This function not only
adjusts the focal point, or the plane of focus, but also optimises the alignment of the two stereo
images to each other, so that a natural and convenient 3D image is obtained on the 3D display.
Depending on the specimen surface and the selected zoom level, it may take a few seconds
until the automatic focus is correctly adjusted. It may also be necessary to optimise the image
with a manual focus correction.
4.4.1 Zoom
•
A
short
press (< 0.5
s) on “
Z+
” or “
Z-
” manually activates an auto
-focus without changing
the zoom level.
•
A
long
press (~1
s) on “
Z+
” or “
Z-
” allows the zoom factor
to be steplessly increased
(“zoom in”) or decreased (“zoom out”).
•
The speed of the zoom function can be changed in the “Settings” menu and adapted to
your needs (see chapter 4.8.1 on page 24).
4.4.2 Focus
The depth of field of the system depends, among other things, on the current lighting and cam-
era settings as well as on the currently set zoom factor. If necessary, you can adjust the focal
point or the plane of focus manually:
•
A
long
press (> 0.5
s) on “
F+
” shifts the plane of focus down.
•
A
long
press (> 0.5
s) on “
F-
” shifts the plane of focus up.
•
The speed of the manual focus function can be changed in the “Settings” menu and
adapted to your needs (see chapter 4.8.1 on page 24).
