EasyColor::Format444To422
Converts a YUV 4:4:4 image to a YUV 4:2:2 image using filtering
Namespace: Euresys::Open_eVision
[C++]
void Format444To422(
EROIC24* sourceImage,
EROIBW16* destinationImage,
bool yFirst
)
Parameters
sourceImage
Pointer to the input image/ROI.
destinationImage
Pointer to the output image/ROI, stored using the 16 bits per pixel format.
yFirst
Flag indicating if the format is YUYVYUYV (
Remarks
In the YUV system, it has been established that sub-sampling the chroma components does not degrade the visual image quality. The 4:4:4 format uses three bytes of information by pixel. The 4:2:2 format is such that only the U and V chroma of the even pixels are kept and they are stored with the even and odd luma, as follows: Thus, only two bytes per pixel are required.
