Detailed Description

Declaration of routines for unpacking a row of pixels in a Bayer frame into separate rows for each channel. Note that the unpacking routines for non-Bayer formats are defined in other files.

Function Documentation

UnpackImageRowBYR3()

CODEC_ERROR UnpackImageRowBYR3	(	uint8_t *	input,
		DIMENSION	width,
		PIXEL *	buffer[],
		PRECISION	bits_per_component[],
		int	channel_count,
		ENABLED_PARTS	enabled_parts
	)

Unpack the Bayer BYR3 format into an unpacked representation.

The Bayer BYR3 format is unpacked into the row-oriented format that is used internally by the codec as an intermediate representation.

Todo:

Add a vector of offsets to each component so that the layout of the components can accommodate requirements on memory alignment.

UnpackImageRowBYR4()

CODEC_ERROR UnpackImageRowBYR4	(	uint8_t *	input,
		DIMENSION	width,
		PIXEL *	buffer[],
		PRECISION	bits_per_component[],
		int	channel_count,
		ENABLED_PARTS	enabled_parts
	)

Unpack the rows of Bayer components.

This routine unpacked that Bayer components into component arrays without applying a component transform which is not defined in VC-5 Part 1.

This routine applies the component transform for Bayer images defined in VC-5 Part 3: Image Formats.

The Bayer image format assigns component arrays to channel numbers in the following order: G sum, G difference, R difference, B difference

This routine unpacked that Bayer components into component arrays without applying a component transform which is not defined in VC-5 Part 1.
