Description
ATW
ATW (automatic tracing white balance) limits the color temperature range
between 2,500 to
8,500˚K to reduce excessive compensation for a large
single-color object. Use it to automatically adjust the WB in real time as
the lighting conditions change. It can be used for both indoor and outdoor
locations.
Set the following options:
Speed: Set the compensation speed. A lower value makes the AWB
faster.
Delay CNT: Set the delay time between automatic adjustments of the
AWB. A smaller value increases the frequency rate of AWB.
ATW Frame: X0.5, X1.0, X1.5, X2.0. Default is X2.0.
Environment: Select Indoor (ATW is compensated for low color
temperature such as from incandescent lighting) or Outdoor (ATW is
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.
User1
This is a fixed white balance that is user-defined by blue and red gain
parameters. Only use this function when there is steady light.
Blue-gain from 0 to 255
Red- gain from 0 to 255
User2
This is a second fixed white balance that is user-defined by blue and red
gain parameters. Only use this function when there is steady light.
Blue-gain from 0 to 255
Red- gain from 0 to 255
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.
Manual
Manually adjust the white balance by blue gain only. The red gain is
automatically adjusted when the blue gain is changed. Only use this
function when there is steady light.
Level UP: Press Enter to increase the WB level.
Level DOWN: Press Enter to decrease the WB level.
Push Lock
Press
Enter
to automatically adjust the white balance to the environment
and lock it at this value.
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.
