OPERATING GUIDELINES
In the event that the white balance is set during an operation, i.e. inside the patient, the en-
doscope must be pulled out of the trocar and the white balance must be set again using gauze.
6.4 FOCUSING
Once the endoscope is connected and the light source is activated, slowly turn the lens focus
ring to find a position where the objects being observed are sharp.
Focusing on a fairly distant point helps obtain adequate field depth for the operation and
therefore avoids having to do retouching too regularly.
6.5 FUNCTIONALITIES
6.5.1 VIDEO SETTINGS
Once the white balance is set, or the "Start" button has been pressed, access to the video set-
tings is authorised.
In this way, it is possible to work directly on brightness, sharpness and red gain.
Additional settings are available by clicking the "More settings" button.
The following parameters can be modified:
BRIGHTNESS
BLUE GAIN
RED GAIN
COLOUR
NOISE REDUCTION
APERTURE
GAMMA
SHARPNESS
GAIN
RED PHASE
This parameter varies the general brightness of the image
Colorimetry shift from white to blue
Colorimetry shift from white to red
Modifies colour saturation
Reduces the noise in an image
Analysis aperture on the shutter (electronic iris): image surface on
which the camera analyses the quantity of light received, in order
to adapt the shutter speed to obtain the proper exposure time. This
function is used to obtain good exposure even when the image has
areas of widely varying illumination (e.g. a dark orifice with very
light surrounding areas requires a small aperture).
Modifies the dynamics of the dark areas:
+1 reduces the difference between the light portions and the dark
portions, therefore making these dark areas appear less so.
-1 does the opposite: the dark portions are made even darker.
Modifies the sharpness of the image to obtain a 3D effect or on the
other hand, softens the image with the anti-moiré filter for flexible
endoscopes.
Modifies the brightness level in cases of mediocre lighting conditions
