Apply white balance
– Sodium lamp auto mode allows the camera to continually adjust for optimal color
reproduction in an environment with sodium vapor light sources (street lighting).
White balance
– Basic auto mode allows the camera to continually adjust for optimal color reproduction
using an average reflectance method. This is useful for indoor light sources and for
colored LED light illumination.
B-gain
In Manual RGB white balance mode, adjust the blue gain slider to offset the factory white
point alignment (reducing blue introduces more yellow).
Default
Click Default to set all video values to their factory setting.
– Dominant color auto mode takes into account any dominant color in the image (for
example, the green of a football pitch or of a gaming table) and uses this information to
obtain a well balanced color reproduction.
G-gain
In Manual RGB white balance mode, adjust the green gain slider to offset the factory white
point alignment (reducing green introduces more magenta).
– In Manual RGB mode, the Red, Green, and Blue gain can be set manually to a desired
position.
Note:
It is only necessary to change the white point offset for special scene conditions.
R-gain
In Manual RGB white balance mode, adjust the red gain slider to offset the factory white
point alignment (reducing red introduces more cyan).
RGB-weighted white balance
In an auto mode, RGB-weighted white balance can be switched On or Off. When On,
additional fine tuning of the automatic color reproduction can be made with the R, G and B
weight sliders.
– Standard auto mode allows the camera to continually adjust for optimal color
reproduction in an environment with natural light sources.
7.4.3 ALC
ALC level
Adjust the video output level.
Select the range within which the ALC will operate. A positive value is more useful for low-
light conditions; a negative value is more useful for very bright conditions.
ALC mode
Select the mode for automatic light-level control:
– Fluorescent 50Hz
– Fluorescent 60Hz
– Standard
ALC - average vs. peak
The ALC - average vs. peak slider configures the ALC level so that it controls mainly on
scene average level (slider position - 15) or on scene peak level (slider position +15). Scene
peak level is useful for capturing images that contain car headlights.
