Configuration and Operation
5.6.3.1
White Balance
A camera needs to find a reference color temperature as a way of measuring the quality of a light source
for calculating all other colors. The unit for measuring this ratio is in Kelvin (°K) degrees. You can select
one of the White Balance control modes according to the operating environment. The table below shows
the color temperature of some light sources for reference.
Select one of the following white balance modes:
·
Auto – The Auto Balance White mode computes the white balance value output using color
information from the entire screen. It is suitable for an environment with a light source color
temperature in the range of approximately 2,700 ~ 7,500K. This is the default setting.
·
ATW (Auto Tracking White Balance) – The Auto Tracking White Balance function automatically
adjusts the white balance in a scene while temperature color is changing. The ATW Mode is
suitable for an environment with a light source color temperature in the range of approximately
2500 ~ 10,000K. This is the default setting.
·
One Push – This button activates the factory-optimized setting for white balance. This setting
may not be ideal for every lighting environment.
·
Manual – In this mode, you can manually change the white balance value. You can select a
number between 0 – 127 for either/both Rgain and Bgain to increase the red and/or blue
luminance.
The setting is applied automatically.
5.6.3.2
Backlight Compensation
Backlight compensation is used in images where a bright light source is behind the subject of interest.
Without backlight compensation, the subject would normally appear in silhouette. The backlight function
of the camera allows it to adjust the exposure of the entire image to properly expose the subject in the
foreground.
Backlight compensation is available only when the TV System is set to 50 fps (PAL) or 60 fps (NTSC) on
the Camera > Misc. screen and the WDR Function is set to Off on the Advanced Picture Settings
screen. Otherwise, this function is not displayed on this screen.
From the Backlight drop-down menu, select On or Off. The default setting is Off. The setting is applied
automatically.
