5.3 White Balance Control
The screen color can be adjusted by using the WHITE BALANCE function.
1. Please direct the arrow to point to “WHITE BAL” on the SETUP menu by adjusting the
switch to UP or DOWN direction.
2. Please select the mode you would like to operate by adjusting the switch to LEFT or
RIGHT direction.
Please select one of the 3 modes below:
Ö ATW (Auto Tracking White Balance): This mode can be used within the color
temperature range from 2,500°K to 8,300°K (eg, fluorescent light, outdoor, sodium
vapor lamp or inside tunnels).
Ö AWC (Auto White Balance Control): Press the SET button while the camera is
directed at a piece of white paper to get the optimum state under the present
illumination. If the environment and the light source are changed, you need to adjust the
white balance again.
Ö MANUAL: The manual adjustment mode enables a more precise adjustment. Please
select ATW or AWC first. Then change to manual adjustment mode and press the SET
button. Set the suitable color temperature, and increase or decrease the red and blue
color values at the same time while checking the color changes of the object.
NOTE:
Under the following conditions, the WHITE BALANCE function may not operate well. In
such cases, please select the AWC mode.
1. When the object’s surroundings have a high color temperature.
2. When the object’s surroundings are dark.
3. If the camera faces a fluorescent light directly or is installed in a place where the
illumination changes constantly, the WHITE BALANCE function may become unstable.
