S7 / OPMI PROergo Device overview
Option "SpeedFocus (Autofocus)"
The SpeedFokus autofocus option permits you to select and automatically
focus on a feature in the ROI (region of interest, measuring field) in the image
of the surgical field.
The SpeedFokus (autofocus) function is based on the analysis of the video
image contrast: during focusing of the microscope's Varioskop optics,
SpeedFokus continuously determines the video image contrast in the selected
ROI. In this way, SpeedFokus controls the microscope's Varioscope optics and
adjusts it to the point of maximum contrast. This corresponds at the same
time to the point of greatest image sharpness.
Autofocus menu
The Autofocus menu offers you the following functions for selection:
– ROI, on/off: activating/deactivating the ROI display.
– ROI Size, small/medium/large: selecting the ROI size.
– ROI Position: branching to the AF - ROI Position submenu to define the
ROI position.
– "Brake Automatic, on/off", activating/deactivating the automatic start of
the focusing process
– Camera Position, left/right: entering the orientation of the external video
camera.
– Advanced Settings: branching to the Advanced Settings submenu to enter
the technical data of the external video camera.
– The "Camera Position left/right" and "Advanced Settings" functions are
only offered for selection if your system is equipped with an external video
camera. If you have an integrated video camera, these fields remain blank.
– As long as you are entering any settings in the Autofocus menu or its
submenus, the ROI is displayed as a square frame in the video image on
the monitor. A few seconds after your last action, the frame disappears
from the screen.
