Color
The Color menu consists of the following items:
AWB:
adjustments for the automatic color balance.
Color Temp RG: color temperature red-green
Color Temp BG: color temperature blue-green
Saturation:
color saturation
Gamma:
nonlinear luminance adaptation
7.2.1
AWB
The camera comes with an automatic white balance that is performed either one-time or continuously. In both cases, the
AWB makes sure that the color components red, green and blue are balanced in the image.
As a rule, you obtain a correct color reproduction, if the color balance is adapted to the lighting. For this, please point the
camera to a white object or surface under the respective lighting conditions and perform the white balance.
For a one-time white balance, the setting has to be PUSH BUTTON. Perform the white balance by pressing the button on the
camera housing.
A continuous white balance is only recommended if all color components are evenly presented in a scene. This is
the case for outdoor scenes. The automatic white balance will provide a wrong color reproduction for mainly
monochrome scenes.
Set the automatic white balance to MANUAL, if you want to adjust the color settings manually.
7.2.2
Color Temp RG and Color Temp BG
Here you can manually adjust the color temperature. You can only select these menu items if AWB is set to MANUAL. You
can vary the balance of colors to obtain a „warmer“ or „colder“ color reproduction.
7.2.3
Saturation
Also color saturation is an item for the optimization of the color reproduction with regard to individual preferences and
monitor properties. Color reproduction can be adapted from rich colors to a monochrome color reproduction.
7.2.4
Gamma
Due to the principles of visual perception and technical characteristics of monitors, a nonlinear adaptation of the image is
recommended for a realistic display of (color) images.
The menu provides fine adjustment for nonlinearity. A Gamma value lower than 1 enhances the dark areas in the scene
compared to the bright areas. For Gamma values higher than 1 it is the other way round. The default 0.45 ITU709 is a
standard waveform, which adapts the brightness profile to most monitors.
