Converts a YUV422 (v210) image to a RGB/BGR image for ITU-R BT.709 HDTV signal.

Syntax

IppStatus ippiYUV422v210ToRGB_709HDTV_32u16u_C3(const Ipp32u* pSrc, int srcStep, Ipp16u* pDst, int dstStep, IppiSize roiSize);

IppStatus ippiYUV422v210ToBGR_709HDTV_32u16u_C3(const Ipp32u* pSrc, int srcStep, Ipp16u* pDst, int dstStep, IppiSize roiSize);

Parameters

pSrc

Pointer to the source image ROI.

srcStep

Distance, in bytes, between starts of consecutive lines in the source image.

pDst

Pointer to the destination image ROI.

dstStep

Distance, in bytes, between starts of consecutive lines in the destination image.

roiSize

Size of the source and destination ROI in pixels.

Description

This function operates with ROI (see Regions of Interest in Intel IPP).

This function converts the YUV image pSrc, packed in the 4:2:2 sampling format, to the gamma-corrected RGB/BGR image pDst for digital component video signals in compliance with the ITU-R BT.709 Recommendation [ITU709] for high-definition TV (HDTV). The source YUV image has the following sequence of bytes: UYV|YUY|VYU|YVY, ... . The conversion is performed according to the following formulas:

R = Y + 1.540*(V - 512)

G = Y - 0.459*(V - 512) - 0.183*(U - 512)

B = Y + 1.816*(U - 512)

The output RGB/BGR values are saturated to the range R [0..31], G [0..63], B [0..31].

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or a warning.

ippStsNullPtrErr

Indicates an error condition if pSrc or pDst is NULL.

ippStsSizeErr

Indicates an error condition if roiSize has a field with a zero or negative value.
