The White Balance menu is used to carry out a white balance.
Fig.56: White Balance menu
During the white balance, an internal correction program auto-
matically compensates errors in the edge areas of the video curve
that are caused by the optic properties of the zoom lens and the
light source.
After the white balance has been completed, the display shows
two video curves:
■ The orange curve shows the video curve recorded by the CCD
camera.
■ The green curve shows the calibrated video curve (after white
balance).
