Detailed Description

Adjusts to changes in lighting conditions to maintain consistent color perception despite variations in light sources.

In industrial imaging, white balance can fail due to the lack of a neutral reference in the image, such as when the scene contains no gray or white areas, or when the colors are unevenly distributed (as in images dominated by a single color). In these cases, traditional white balance algorithms, like the gray world method, may fail to produce accurate color corrections.

Chromatic adaptation provides an alternative solution by adjusting the image’s colors based on the known or estimated correlated color temperature of the light source.

Note

If chromatic adaption is used in combination with white balance, the result is indefinite.

Defaults

• chromatic adaption algorithm = Bradford
• color space = SRGB_D65
• color temperature = undefined (chromatic adaption won't be applied)

IsEnabled()

bool IsEnabled ( ) const

inlineoverridevirtual

Gets whether this feature is currently enabled.

Returns

true if enabled; otherwise false.

Since

ids_peak_icv 1.0

Implements IFeature.

ResetToDefault()

void ResetToDefault ( )

inlineoverridevirtual

Resets the chromatic adaption configuration to the default values.

Note

The enabled state does not change when calling this function.

Since

ids_peak_icv 1.3

Implements IFeature.

SetAlgorithm()

void SetAlgorithm ( ChromaticAdaptionAlgorithm algorithm )

inline

Sets the algorithm used for chromatic adaption.

The algorithms use a CAT (chromatic adaptation transform) matrix.

Parameters

algorithm

The chromatic adaption algorithm to set.

Since

ids_peak_icv 1.3

SetColorTemperature()

void SetColorTemperature ( uint32_t kelvin )

inline

Sets the color temperature of the light source. If no color temperature is explicitly set the chromatic adaption won't be applied.

Parameters

kelvin

The color temperature in Kelvin to set. Must be within the allowed GetColorTemperatureRange.

Since

ids_peak_icv 1.3

SetEnabled()

void SetEnabled ( bool enabled )

inlineoverridevirtual

Enables or disables the feature.

Parameters

enabled

Set to true to enable, or false to disable.

Since

ids_peak_icv 1.0

Implements IFeature.

SetTargetColorSpace()

void SetTargetColorSpace ( ColorSpace colorSpace )

inline

Sets the target color space.

A color space is a specific implementation of a color model, mapping colors to a defined range of values (e.g., standard primaries, white point, and gamma).

Parameters

colorSpace

The color space to set.
