Operation In Automatic Mode; White Balance - Comeg SOPRO 184 Manuel D'utilisation

7 Operation in automatic
mode
This video camera is equipped with an automatic mode for adjusting the video parameters. In just two
steps, the video camera will be operational. This mode is activated by default.
7.1 Selection of the type of endoscope
Select the rigid endoscope (endoscope with diameters of 1.9 to 10 mm fi tted with lenses) or the fl exible
endoscope (endoscope fi tted with fi bre optics) in the Optics tab on the screen [L2] by pressing on the
wheel [S2].
7.2 Focusing
Use the wheel [S4] on the sensor to carry out the focusing.
Once the endoscope is connected and the source is activated, turn the wheel slowly in order to fi nd a
position where the objects observed are in sharp focus.
Carrying out focusing quite far away enables you to obtain suffi cient fi eld depth for the operation,
which does away with the need to regularly carry out focusing adjustments.

7.3 White balance

There are two ways of initiating the white balance.
1. From the control channel unit, by pressing the wheel when the AWB white balance icon is selected.
2. From the button [S7] from the straight sensor.
You should carry out the following steps:
• Once the video camera is connected to the endoscope, the ambient light is reduced to a minimum, and
the light source is active, fi lm a white surface.
• Activate the white balance; the message "Balance In Progress" will appear on the OLED screen of the
control channel unit, or 4 white squares will appear on-screen.
• Continue to fi lm the white surface until the "Balance In Progress" message on the OLED screen of the
control channel unit disappears, or until the 4 white squares disappear.
• At the end of the white balance process, a square matching the size of the endoscope used will appear
on-screen; this defi nes the exposure window calculated by the video camera.
If you use one of the buttons on the head of the video camera, keep the button pressed until the
"Balance In Progress" message is obtained and then release it; this time delay will avoid unintentional
pressing on the button.
