White balance
Use this menu options to define the white balance adjustment.
Display: WHITE BAL 
ATW 
ATW = auto-tracking white balance. White balance 
makes sure that white objects are always reproduced 
correctly. The ATW option controls the automatic white 
balance adjustments. For most environments, the default 
settings are sufficient. 
 SPEED: controls how fast the camera will adjust the
white balance. The higher the setting, the faster the
adjustment. 
Note: a too fast adjustment can result in colour 
oscillation. 
 DELAY CNT: specifies how often the camera checks
for colour changes and apply the ATW settings. The 
lower the number, the more frequent the checks and 
adjustments.
 ATW FRAME: sets the frame magnification for the
camera to identify the colour changes. (Recommended
setting is 1.0.)
 ENVIRONMENT: choose INDOOR for indoor
environments, and OUTDOOR for outdoor
environments.
PUSH
This is a fixed setting.

USER2
These are two user-definable setting that let you control
red and blue gain. This can be useful in environments 
that are saturated with a single colour of light (for 
example bars or entertainment venues), or it can help 
vision-impaired (colour-blind) users.
ANTI CR Anti colour rolling. Some types of lighting can cause
colour bars rolling over the screen. Use this setting to
compensate.
MANUAL When you switch the camera on, it will acquire a white
balance value from the whitest object in view. The
camera will then reproduce white colour based on this 
value, regardless of changes in colour temperature or 
other factors. If this value gives insufficient colour 
quality, you can manually adjust the balance between 
red and blue levels to improve the image.
