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 ( FrameBuffer * input, FrameBuffer * output, DebayerParams params )

virtual

Process the bayer data into the requested format.

Parameters

[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.
