3.6.3.1 Setting for Visualization with Stable Lighting
The typical camera for these purposes is the FireWire-CAM-002.
Under the assumption that there are stable lighting conditions we
recommend the following settings (see Windows dialogues in
section 2.5.3):
Shutter and Gain: Keep Gain as low as possible and Shutter as high
as possible, since Gain not only amplifies the picture signal but also
amplifies image noise.
High Shutter values (longer exposure times) can also lead to motion
blur. Determine through calculation or experimentation the highest
reasonable value and set the Gain accordingly, so that the picture
brightness is optimized. If necessary adjust the lens aperture to
improve the image.
Brightness: Keep the Brightness setting as low as possible. This
guarantees the highest gray value dynamic.
Sharpness: Adjust the sharpness of the picture according to the visual
impression that it makes. Be aware that too high of a Sharpness setting
will also show noise more clearly and may have an unnatural effect on
the image. Before adjusting the Sharpness setting, be sure that focus
and aperture (=depth of field) settings on the lens are optimized.
Gamma: If you are displaying the pictures on a tube monitor, Gamma
should be active. For most other cases Gamma should be shut off.
Select the setting according to the visual impression you desire.
Saturation: For a „realistic“ image, in most cases it is recommended
that the color saturation adjustment is deactivated. Otherwise a value
between 50 and 80 will usually deliver the best results.
White Balance: Use the switch One Push White Balance to get a
base value. With some slight adjustments afterwards you should easily
be able to find the optimal setting.
In most cases the automatic white balance („Auto“) does an adequate
job.
