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 an 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 color coding, a Y value is transmitted for each pixel, but the U and V values
are only transmitted for every second pixel.
The order of the pixel data for a received frame in the image buffer in your PC is similar to the order
of YUV 4:2:2 Packed output from a color camera.
For more information about the YUV 4:2:2 Packed format on color cameras, see Section 9.3.4 on
page 177.

YUV 4:2:2 (YUYV) Packed Format

When a monochrome camera is set for the YUV 4:2:2 (YUYV) 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 (YUYV) Packed.
The Y value transmitted for each pixel is an 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 color coding, a Y value is transmitted for each pixel, but the U and V values
are only transmitted for every second pixel.
The order of the pixel data for a received frame in the image buffer in your PC is similar to the order
of YUV 4:2:2 (YUYV) Packed output from a color camera.
