9.2.4 YUV 4:2:2 Packed Format
When a monochrome camera is set for the YUV 4:2:2 Packed pixel data format, the camera
transmits Y, U, and V values in a fashion that mimics the output from a color camera set for YUV
4:2:2 Packed.
The Y value transmitted for each pixel is the actual 8 bit brightness value similar to the pixel data
transmitted when a monochrome camera is set for Mono 8. The U and V values transmitted will
always be zero. With this format, a Y value is transmitted for each pixel, but the U and V values are
only transmitted for every second pixel.
The table below describes how the pixel data for a received frame will be ordered in the image buffer
in your PC when the camera is set for YUV 4:2:2 Packed output.
The following standards are used in the table:
P
0
= the first pixel transmitted by the camera
P
n
= the last pixel transmitted by the camera
B
0
= the first byte in the buffer
B
m
= the last byte in the buffer
