Every two consecutive samples are packed into three 23bytes. Each of the first two bytes contain the 8 high order bits of 24the pixels, and the third byte contains the four least significant 25bits of each pixel, in the same order. 26 27Each n-pixel row contains n/2 green samples and n/2 blue or red 28samples, with alternating green-red and green-blue rows. They are 29conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. 30Below is an example of a small V4L2_PIX_FMT_SBGGR12P image: 31 32**Byte Order.** 33Each cell is one byte. 34 35.. tabularcolumns:: |p{2.2cm}|p{1.2cm}|p{1.2cm}|p{3.1cm}|p{1.2cm}|p{1.2cm}|p{6.4cm}| 36 37 38.. flat-table:: 39 :header-rows: 0 40 :stub-columns: 0 41 :widths: 2 1 1 1 1 1 1 42 43 44 - - start + 0: 45 - B\ :sub:`00high` 46 - G\ :sub:`01high` 47 - G\ :sub:`01low`\ (bits 7--4) 48 49 B\ :sub:`00low`\ (bits 3--0) 50 - B\ :sub:`02high` 51 - G\ :sub:`03high` 52 - G\ :sub:`03low`\ (bits 7--4) 53 54 B\ :sub:`02low`\ (bits 3--0) 55 56 - - start + 6: 57 - G\ :sub:`10high` 58 - R\ :sub:`11high` 59 - R\ :sub:`11low`\ (bits 7--4) 60 61 G\ :sub:`10low`\ (bits 3--0) 62 - G\ :sub:`12high` 63 - R\ :sub:`13high` 64 - R\ :sub:`13low`\ (bits 7--4) 65 66 G\ :sub:`12low`\ (bits 3--0) 67 - - start + 12: 68 - B\ :sub:`20high` 69 - G\ :sub:`21high` 70 - G\ :sub:`21low`\ (bits 7--4) 71 72 B\ :sub:`20low`\ (bits 3--0) 73 - B\ :sub:`22high` 74 - G\ :sub:`23high` 75 - G\ :sub:`23low`\ (bits 7--4) 76 77 B\ :sub:`22low`\ (bits 3--0) 78 - - start + 18: 79 - G\ :sub:`30high` 80 - R\ :sub:`31high` 81 - R\ :sub:`31low`\ (bits 7--4) 82 83 G\ :sub:`30low`\ (bits 3--0) 84 - G\ :sub:`32high` 85 - R\ :sub:`33high` 86 - R\ :sub:`33low`\ (bits 7--4) 87 88 G\ :sub:`32low`\ (bits 3--0) 89
