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.

USER1

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.
