27Description
28===========
29
30These four pixel formats are raw sRGB / Bayer formats with 12 bits per
31colour. Each colour component is stored in a 16-bit word, with 4 unused
32high bits filled with zeros. Each n-pixel row contains n/2 green samples
33and n/2 blue or red samples, with alternating red and blue rows. Bytes
34are stored in memory in little endian order. They are conventionally
35described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
36of a small V4L2_PIX_FMT_SBGGR12 image:

38**Byte Order.**
39Each cell is one byte, the 4 most significant bits in the high bytes are
400.
