V4L2_PIX_FMT_SBGGR12 — 12-bit Bayer formats expanded to 16 bits
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 one of these formats
V4L2_PIX_FMT_SBGGR12 4 × 4
Byte Order. Each cell is one byte, high 6 bits in high bytes are 0.
