Whitebalance

BalanceRatioAbs [Float] R/W

Adjusts the gain of the channel selected in the BalanceRatioSelector.

BalanceRatioAbs = 1.00 means no gain is applied.

BalanceRatioSelector [Enum] R/W

Select the Red or Blue channel to adjust with BalanceRatioAbs.

BalanceWhiteAuto [Enum] R/W

Auto algorithms use information from the camera’s current image and apply the

following settings to the next image; i.e., the camera must be acquiring images

in order for the auto algorithm to update. Large changes in scene lighting may

require 2-3 frames for the algorithm to stabilize.

You can configure the auto white balance feature to respond only to a subregion

within the image scene. This subregion can be configured with the DSPSub-

region feature.

BalanceWhiteAutoControl

BalanceWhiteAutoAdjustTol [Integer] R/W

Tolerance allowed from the ideal white balance values, within which the auto

white balance does not run. It is used to limit white balance setting changes to

only larger variations in color.

Range: [Camera dependent]

Note



The green channel gain is always 1.00, as this is the lumi-

nance/reference channel. To increase/decrease green,

decrease/increase red and blue accordingly.

Possible values: Red, Blue Default: Red

Off [Default] Auto white balance is off. White balance can be

adjusted directly by changing the BalanceRatioSe-

lector and BalanceRatioAbs

Once Valid when ExposureMode = Timed or

PieceWiseLinearHDR. A single iteration of the auto

white balance algorithm is run, and then

BalanceWhiteAuto returns to Off. The Once function

operates according to the ExposureAuto and

DSPSubregion controls

Continuous Valid when ExposureMode = Timed or

PieceWiseLinearHDR. White balance will continuously

adjust according to the current scene. The continuous

function operates according to the ExposureAuto and

DSPSubregion controls

Range: [0–50] Default: 5 Unit: Percent
