EColorLookup::WhiteBalance
Initializes a color lookup table that can be used for color adjustment, including a global gain, gamma pre-compensation [cancellation] and white balancing.
Namespace: Euresys::Open_eVision
[C++]
void WhiteBalance(
float gain,
float gamma,
float balanceRed,
float balanceGreen,
float balanceBlue
)
Parameters
gain
Global gain to be applied to all three color components. By default, the image intensity remains unchanged.
gamma
Gamma exponent. Setting this parameter will cancel the gamma pre-compensation feature of the camera, or apply it. By default, the no gamma pre-compensation is assumed (linear response). The gamma exponent can be chosen among the predefined values EasyColor::CompensateNtscGamma/EasyColor::CompensatePalGamma/EasyColor::CompensateSmpteGamma (pre-compensation) or EasyColor::NtscGamma/EasyColor::PalGamma/EasyColor::SmpteGamma (pre-compensation cancellation), or be user-defined.
balanceRed
Color values to be used for white balance. These parameters should be set to the measured average values of a white (or gray) pixels area, allowing the white balance to adjust pre-component gains appropriately. Use function EasyImage::PixelAverage to obtain them. By default, no white balancing is performed.
balanceGreen
Color values to be used for white balance. These parameters should be set to the measured average values of a white (or gray) pixels area, allowing the white balance to adjust pre-component gains appropriately. Use function EasyImage::PixelAverage to obtain them. By default, no white balancing is performed.
balanceBlue
Color values to be used for white balance. These parameters should be set to the measured average values of a white (or gray) pixels area, allowing the white balance to adjust pre-component gains appropriately. Use function EasyImage::PixelAverage to obtain them. By default, no white balancing is performed.
Remarks
To apply some transform to a color image, you initialize the color lookup once for all and use it at will with EColorLookup::Transform or EasyColor::TransformBayer operation.
