Each colour component is stored in a 16-bit word, with 4 unused 25high bits filled with zeros. Each n-pixel row contains n/2 green samples 26and n/2 blue or red samples, with alternating red and blue rows. Bytes 27are stored in memory in little endian order. They are conventionally 28described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example 29of a small V4L2_PIX_FMT_SBGGR12 image: 30 31**Byte Order.** 32Each cell is one byte, the 4 most significant bits in the high bytes are 330. 34 35 36 37 38.. flat-table:: 39 :header-rows: 0 40 :stub-columns: 0 41 42 * - start + 0: 43 - B\ :sub:`00low` 44 - B\ :sub:`00high` 45 - G\ :sub:`01low` 46 - G\ :sub:`01high` 47 - B\ :sub:`02low` 48 - B\ :sub:`02high` 49 - G\ :sub:`03low` 50 - G\ :sub:`03high` 51 * - start + 8: 52 - G\ :sub:`10low` 53 - G\ :sub:`10high` 54 - R\ :sub:`11low` 55 - R\ :sub:`11high` 56 - G\ :sub:`12low` 57 - G\ :sub:`12high` 58 - R\ :sub:`13low` 59 - R\ :sub:`13high` 60 * - start + 16: 61 - B\ :sub:`20low` 62 - B\ :sub:`20high` 63 - G\ :sub:`21low` 64 - G\ :sub:`21high` 65 - B\ :sub:`22low` 66 - B\ :sub:`22high` 67 - G\ :sub:`23low` 68 - G\ :sub:`23high` 69 * - start + 24: 70 - G\ :sub:`30low` 71 - G\ :sub:`30high` 72 - R\ :sub:`31low` 73 - R\ :sub:`31high` 74 - G\ :sub:`32low` 75 - G\ :sub:`32high` 76 - R\ :sub:`33low` 77 - R\ :sub:`33high` 78
