12-bit Bayer formats expanded to 16 bits

Description
|
||
|
|
===========
|
||
|
|
|
||
|
|
These four pixel formats are raw sRGB / Bayer formats with 12 bits per
|
||
|
|
colour. Each colour component is stored in a 16-bit word, with 4 unused
|
||
|
|
high bits filled with zeros. Each n-pixel row contains n/2 green samples
|
||
|
|
and n/2 blue or red samples, with alternating red and blue rows. Bytes
|
||
|
|
are stored in memory in little endian order. They are conventionally
|
||
|
|
described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
|
||
|
|
of a small V4L2_PIX_FMT_SBGGR12 image:
|
||
|
|
|
||
|
|
**Byte Order.**
|
||
|
|
Each cell is one byte, the 4 most significant bits in the high bytes are
|
||
|
|
0.
