Auto White Balance (AWB) Calibration
In some installations, use the auto white balance (AWB) feature of the CCC5100H Series camera to render the most accurate image color
possible. Mixed color applications may affect the amount of color adjustment. For example, a small white object on a large blue surface may
have a reddish tint. AWB uses a calibration image to identify the correct white level. The camera then uses this white level when adjusting
overall image color.
NOTE: AWB is recommended only for indoor applications that have a single primary light source.
Example: A CCC5100H Series camera is installed in a pan/tilt enclosure in a clothing store in a shopping mall. Mixed colors are located
throughout the store. Overhead lights provide the primary illumination, but some light also enters the store from the mall. As the camera pans a
section filled with blue clothing, the camera may redden the image to compensate for the blue. When properly calibrated, the camera will not try
to adjust scenes with predominant amounts of red or blue.
To calibrate auto white balance:
1. Focus the camera on a neutral color scene. Select a neutral scene with the following characteristics:
• Little or no black
• Not predominantly red
• Not predominantly blue
• No direct light source, such as a lamp or a window
2. Display the WHITE BALANCE menu.
3. Change the MODE setting to AUTO WHITE BALANCE.
4. Use a short center press to calibrate the AWB settings to the neutral scene.
5. Select EXIT to close the setup menus.
6. Focus the camera on the target scene.
7. As soon as you finish customizing this and all other camera settings, save your custom
settings into a user-definable profile. Then change the default profile to CUSTOM1 or
CUSTOM2. This protects them in case the camera loses power or must be restarted
(refer to Profiles Menu for more information).
