11.9. Camera - WB
To display natural colours, the camera needs to know the reference colour temperature of the light source.
Based on this reference colour temperature the camera will calculate the correct values for all colours. The
camera can perform a measurement by itself or the user can set up the reference colour temperature manually.
The scale unit of the colour temperature is Kelvin [K]. The following list shows the colour temperature of some
light sources for reference.
The users can select one of the White Balance Control modes according to the operating environment.
Light Sources :
Cloudy Sky (Colour Temperature: 6,000 to 8,000 K)
Noon Sun and Clear Sky (Colour Temperature: 6,500 K)
Household Lighting (Colour Temperature: 2,500 to 3,000 K)
75-watt Bulb (Colour Temperature: 2,820 K)
Candle Flame (Colour Temperature: 1,200 to 1,500 K)
Auto Mode :
In this mode, the white balance works within its colour temperature range and calculates the best-fit white
balance.
Indoor/Outdoor Mode :
Select Indoor or Outdoor.
ATW Mode (Auto Tracing White Balance) :
The Dome Camera adjusts the White Balance continously in a range from 2000 K to 10000 K.
Manual Mode :
In this mode, the users can change the White Balance value manually via specifying R-Gain and B-Gain. The
range of R/B-Gain is from 0 to 255.
