Detailed Description

Class for debayering on the CPU.

Implementation for CPU based debayering

Constructor & Destructor Documentation

◆ DebayerCpu()

libcamera::DebayerCpu::DebayerCpu ( std::unique_ptr< SwStatsCpu > stats )

Constructs a DebayerCpu object.

Parameters

[in] stats Pointer to the stats object to use

Member Function Documentation

◆ configure()

int libcamera::DebayerCpu::configure	(	const StreamConfiguration &	inputCfg,
		const std::vector< std::reference_wrapper< StreamConfiguration >> &	outputCfgs
	)

virtual

Configure the debayer object according to the passed in parameters.

Parameters

[in]	inputCfg	The input configuration
[in]	outputCfgs	The output configurations

Returns: 0 on success, a negative errno on failure

Implements libcamera::Debayer.

◆ formats()

std::vector< PixelFormat > libcamera::DebayerCpu::formats ( PixelFormat inputFormat )

virtual

Get the supported output formats.

Parameters

[in] inputFormat The input format

Returns: All supported output formats or an empty vector if there are none

Implements libcamera::Debayer.

◆ frameSize()

unsigned int libcamera::DebayerCpu::frameSize ( )

inline

Get the output frame size.

Returns: The output frame size

◆ getStatsFD()

const SharedFD& libcamera::DebayerCpu::getStatsFD ( )

inline

Get the file descriptor for the statistics.

Returns: the file descriptor pointing to the statistics

◆ patternSize()

Size libcamera::DebayerCpu::patternSize ( PixelFormat inputFormat )

virtual

Get the width and height at which the bayer pattern repeats.

Parameters

[in] inputFormat The input format

Valid sizes are: 2x2, 4x2 or 4x4.

Returns: Pattern size or an empty size for unsupported inputFormats

Implements libcamera::Debayer.

◆ process()

void libcamera::DebayerCpu::process	(	uint32_t	frame,
		FrameBuffer *	input,
		FrameBuffer *	output,
		DebayerParams	params
	)

virtual

Process the bayer data into the requested format.

Parameters

[in]	frame	The frame number
[in]	input	The input buffer
[in]	output	The output buffer
[in]	params	The parameters to be used in debayering

Note: DebayerParams is passed by value deliberately so that a copy is passed when this is run in another thread by invokeMethod().

Implements libcamera::Debayer.

◆ sizes()

SizeRange libcamera::DebayerCpu::sizes	(	PixelFormat	inputFormat,
		const Size &	inputSize
	)

virtual

Get the supported output sizes for the given input format and size.

Parameters

[in]	inputFormat	The input format
[in]	inputSize	The input size

Returns: The valid size ranges or an empty range if there are none

Implements libcamera::Debayer.

◆ strideAndFrameSize()

std::tuple< unsigned int, unsigned int > libcamera::DebayerCpu::strideAndFrameSize	(	const PixelFormat &	outputFormat,
		const Size &	size
	)

virtual

Get the stride and the frame size.

Parameters

[in]	outputFormat	The output format
[in]	size	The output size

Returns: A tuple of the stride and the frame size, or a tuple with 0,0 if there is no valid output config

Implements libcamera::Debayer.
