Detailed Description

Class representing one CPU debayering thread.

Implementation for CPU based debayering threads.

Constructor & Destructor Documentation

DebayerCpuThread()

libcamera::DebayerCpuThread::DebayerCpuThread	(	DebayerCpu *	debayer,
		unsigned int	threadIndex,
		bool	enableInputMemcpy
	)

Construct a DebayerCpuThread object.

Parameters

[in]	debayer	pointer back to the DebayerCpuObject this thread belongs to
[in]	threadIndex	0 .. n thread-index value for the thread
[in]	enableInputMemcpy	when set copy input data to a heap buffer before use

Member Function Documentation

configure()

void libcamera::DebayerCpuThread::configure	(	unsigned int	yStart,
		unsigned int	yEnd
	)

Configure thread to process a specific part of the image.

Parameters

[in]	yStart	y coordinate of first line to process
[in]	yEnd	y coordinate of the line at which to stop processing

Configure the thread to process lines from yStart to yEnd - 1.

process()

void libcamera::DebayerCpuThread::process	(	uint32_t	frame,
		const uint8_t *	src,
		uint8_t *	dst
	)

Process part of the image assigned to this debayer thread.

Parameters

[in]	frame	The frame number
[in]	src	The source buffer
[in]	dst	The destination buffer
