compensated for high color temperature such as from daylight). Default is
Indoor.
Push
Like ATW, the Push function continually monitors/analyzes the color
temperature of the incoming light and corrects the WB. However, Push
has no limits between 1,800 to 10,500
˚
K so it may over-compensate the
WB for a large single-color object.

Anti CR
The anti-color rolling mode function minimizes the color changes over
long periods caused by very small differences between the flicker
frequency of non-inverter fluorescent lights and the drive frequency of the
image sensor devices.

automatically adjusted when the blue gain is changed. Only use this
function when there is steady light.

Set backlight compensation (BLC)
This feature tells the camera to adjust its total exposure (iris and shutter) to
ignore the brightest areas of the image, and instead concentrate on darker areas.
In the Setup Menu, go to
Backlight
and select the options to be modified:
Off
: Option is disabled. Default setting.
BLC (Backlight Compensation)
: BLC can improve image quality when the
background illumination is high. It prevents the object in the center from
appearing too dark.
HLC (Highlight Compensation)
: HLC masks strong light sources, giving darker
areas more detail. It is often used to help identify vehicle license plate numbers,
for example.
