YUV422v210ToRGB, YUV422v210ToBGR
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. |
