Backlight compensation (BLC)
GB
In case of backlight, i. e. light which hits the
lens directly or at an angle from the front, the
object to be monitored will be underexposed.
This is also the case if the object is in front of
a very bright background. The backlight com-
pensation (BLC) will brighten objects in the
centre of the picture which are too dark. For
activating this function, set the upper DIP
switch (5) to the position "BLC". Without any
disturbing backlight, set the switch to "OFF".
Automatic white balance
To obtain a natural colour reproduction, the
white balance will automatically match the
camera to the colour temperature of the light
source used (e. g. fluorescent lamp). Thus, a
faithful colour reproduction will be ensured
even in case of varying lighting conditions.
