NOTE:
For 23× and 35× models, If AE MODE is set as SHUTTER,
IRIS or AGC mode rather than AUTO mode, the following functions
will be turned off automatically: WDR, Digital Slow Shutter and Alarm
Detect. Additionally, when WDR/Alarm Detect is turned on, AE MODE
will become
AUTO
. In the same situation, if the camera’s IR function
was set as IR AUTO mode, it will become invalid even though the
OSD display remains the same.
After completing various parameter setups, please exit the AE MODE menu and
go back to the
Main Page 1
to continue to set the WBC mode.
3.3.6 WBC
MODE
A digital camera needs to find a reference colour temperature, which is a way of
measuring the quality of a light source, in order to correctly calculate all the other
colours. The unit for measuring this ratio is degrees Kelvin (K). You can select one of
the white balance control modes depending on the conditions. The following table
shows the colour temperature of some light sources.
Light source
Colour temperature in K
Cloudy sky
6,000 to 8,000
Noon sun and clear sky
6,500
Household lighting
2,500 to 3,000
75 watt bulb
2,820
Candle flame
1,200 to 1,500
18×/26× Model:

AUTO
In this mode, the white balance function works within its colour temperature
range. This mode computes the white balance value output using colour
information from the entire screen. It outputs the appropriate value using the
colour temperature radiating from a black subject based on a range of values
from 3000K to 7500K.
