Each sample is stored in a 16-bit word, with two 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_SBGGR14 image: + +**Byte Order.** +Each cell is one byte, the two most significant bits in the high bytes are +zero. + + + +.. flat-table:: + :header-rows: 0 + :stub-columns: 0 + :widths: 2 1 1 1 1 1 1 1 1 + + + * - start + 0: + - B\ :sub:`00low` + - B\ :sub:`00high` + - G\ :sub:`01low` + - G\ :sub:`01high` + - B\ :sub:`02low` + - B\ :sub:`02high` + - G\ :sub:`03low` + - G\ :sub:`03high` + * - start + 8: + - G\ :sub:`10low` + - G\ :sub:`10high` + - R\ :sub:`11low` + - R\ :sub:`11high` + - G\ :sub:`12low` + - G\ :sub:`12high` + - R\ :sub:`13low` + - R\ :sub:`13high` + * - start + 16: + - B\ :sub:`20low` + - B\ :sub:`20high` + - G\ :sub:`21low` + - G\ :sub:`21high` + - B\ :sub:`22low` + - B\ :sub:`22high` + - G\ :sub:`23low` + - G\ :sub:`23high` + * - start + 24: + - G\ :sub:`30low` + - G\ :sub:`30high` + - R\ :sub:`31low` + - R\ :sub:`31high` + - G\ :sub:`32low` + - G\ :sub:`32high` + - R\ :sub:`33low` + - R\ :sub:`33high` |
