Real-time auto white balance
The built-in microprocessor adjusts the white balance in real-time by detecting white portion
in the signal sent from the camera. This function is useful when color temperature changes in
lapse of time.
(Note) when illumination is changed from reddish light source (electric bulb or the like) to bluish
one (fluorescent lamp, cloudy sky, or the like), white balance will be lost instantly. This is not
due to failure. White balance will be regained in the lapse of time.
Set WHT BAL to AUTO in the menu mode.
