| 14 | 12-bit Bayer formats expanded to 16 bits |

| 17 | Description |
| 18 | =========== |
| 19 | |
| 20 | These four pixel formats are raw sRGB / Bayer formats with 12 bits per |
| 21 | colour. Each colour component is stored in a 16-bit word, with 4 unused |
| 22 | high bits filled with zeros. Each n-pixel row contains n/2 green samples |
| 23 | and n/2 blue or red samples, with alternating red and blue rows. Bytes |
| 24 | are stored in memory in little endian order. They are conventionally |
| 25 | described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example |
| 26 | of one of these formats |
| 27 | |
| 28 | **Byte Order..** |
| 29 | |
| 30 | Each cell is one byte, high 6 bits in high bytes are 0. |
