Description
|
||
|
|
===========
|
||
|
|
|
||
|
|
In this format each four bytes is two pixels. Each four bytes is two
|
||
|
|
Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr
|
||
|
|
belong to both pixels. As you can see, the Cr and Cb components have
|
||
|
|
half the horizontal resolution of the Y component.
|
||
|
|
|
||
|
|
**Byte Order.**
|
||
|
|
Each cell is one byte.
