Detailed Description

Base debayering class.

Base class that provides functions for setting up the debayering process.

Member Function Documentation

configure()

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

pure 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

Implemented in libcamera::DebayerCpu.

formats()

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

pure 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

Implemented in libcamera::DebayerCpu.

process()

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

pure 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().

Implemented in libcamera::DebayerCpu.

sizes()

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

pure 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

Implemented in libcamera::DebayerCpu.

strideAndFrameSize()

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

pure 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

Implemented in libcamera::DebayerCpu.
