Member Function Documentation

init()

int libcamera::ipa::LscAlgorithmBase::init	(	const ValueNode &	tuningData,
		ControlInfoMap::Map &	controls,
		const LscDescriptor &	descriptor
	)

Parameters

[in]	tuningData	The tuning data
[in]	controls	The IPA list of supported controls
[in]	descriptor	The LSC engine descriptor

Parse tuningData according to the settings specified in descriptor to populate the LSC data and registers LSC controls in controls.

Returns

0 on success, a negative error code otherwise

process()

void libcamera::ipa::LscAlgorithmBase::process	(	lsc::FrameContext &	context,
		ControlList &	metadata
	)

Populate the list of lsc metadata.

Parameters

[in]	context	The lsc frame context
[in]	metadata	The list of metadata

Populates the list of metadata with controls handled by the LscAlgorithm class. The only supported metadata is controls::LensShadingCorrectionEnable.

queueRequest()

void libcamera::ipa::LscAlgorithmBase::queueRequest	(	lsc::ActiveState &	state,
		lsc::FrameContext &	context,
		const ControlList &	controls
	)

Queue a request to the lsc algorithm.

Parameters

[in]	state	The lsc active state
[in]	context	The lsc frame context
[in]	controls	The list of controls associated with a Request

Queue a new list of controls to the lsc algorithm. The only supported control is controls::LensShadingCorrectionEnable.

Member Data Documentation

impl_

libcamera::ipa::LscAlgorithmBase::impl_

protected

The LSC algorithm implementation.

There are two classes derived from LscImplementation, the LscTable and LscPolynomial ones. Which one to instantiate is decided by parsing the tuning file.

polynomial_

libcamera::ipa::LscAlgorithmBase::polynomial_

protected

Boolean flag for polynomial LSC.

Set to true if polynomial LSC is in use.
