5.1 Operating principle

.

The 3 CCD HDTV 5550 endocam provides a digital HDTV video signal, in
particular suited for operating a 16:9 LCD monitor for display purposes.
For recording, both the digital and the analog SD signals can be used.

The color properties of the illumination are referred to as color tempera­tures and are measured in Kelvin (K). Higher color temperatures are blu­ish, lower color temperatures are reddish.
In order to reproduce a picture in true colors, it is necessary to perform
white balance before the first use and after each change of the light pro­jector or endoscopic equipment. White balance is a procedure where the
color gain for the red and blue portions of the video image is adjusted in
such a way that it suits the color temperature of the light projector and
that the 3 CCD HDTV ENDOCAM provides optimum colors. This includes
that white objects are rendered as completely white.
In the 3 CCD HDTV ENDOCAM, the white balance can be performed for
a temperature range of 2300 K to 6000 K.

IMPORTANT!

Depending on the focal length of the objective lens, image information
may be lost if full format is displayed.
In the case of full format, parts of the endoscopic image do not appear on
the monitor (Fig. 2).

Fig. 2

5.2 Controls and modes

Z The ’Auto White Balance’ (AWB) button serves to start the automatic

white balance procedure.

Z ”Preset” button (user settings) -- initial pressing will display the active

preset.

' If this button is pressed again, the display will change to the next pre-

set.

Z The “brightness selection” buttons serve to increase or decrease the

basic brightness for automatic brightness control (shutter function).

Z “Menu” button -- initial pressing of the menu button will access the

menu. Use the arrow buttons to navigate and the “OK” button to
change the selection.

' Pressing “Menu” button serves to exit the menu.

5.3 Operation of device

5.3.1 White balance

.

IMPORTANT!

After each start with the camera head plugged in or plugging in
of the camera head, the user is prompted to perform a white balance.

Z Switch on the light projector and direct the endoscope at a white

surface.

' Make sure that no extraneous light and no colored objects are in the

camera’s field of view.

Z For an initial white balance setting the user can keep depressed either

the “WHITE BALANCE” button of the controller, or any other camera
head button for more than 1 second while “WHITE BALANCE” is dis­played.

' During white balance, the “WHITE BALANCE” message appears and

the writing “AWB” blinks.

' If white balance is completed successfully, the white balance symbol

is displayed in green and a green “OK” appears.

' If white balance is completed unsuccessfully, the white balance sym-

bol is displayed in red and a red “FAIL” appears.
The user is prompted to check the setup and repeat the procedure.
If the white balance is not successfully completed, it is not possible to
use the camera head button again (except when the head button is
programmed for white balance function).
Instead, the “WHITE BALANCE” button on the controller front panel
is used.

5.3.2 Automatic brightness control

The automatic brightness control (shutter function or shutter mode)
of the 3 CCD HDTV ENDOCAM allows the use of light projectors without
light control and light projectors with deactivated video control.

The advantage of the shutter function is very fast response to image brightness.

IMPORTANT!

.

To avoid unnecessary heating of the endoscope when using the shutter
function, set the light intensity of the light projector to a middle value.
The shutter function should not be used together with the video control of
the light projector (switch off video control) because this would lead to
undesirable fluctuations in image brightness.
