| 17 | 12-bit Bayer formats expanded to 16 bits | |

| 20 | Description | |
| 21 | =========== | |
| 22 | ||
| 23 | These four pixel formats are raw sRGB / Bayer formats with 12 bits per | |
| 24 | colour. Each colour component is stored in a 16-bit word, with 4 unused | |
| 25 | high bits filled with zeros. Each n-pixel row contains n/2 green samples | |
| 26 | and n/2 blue or red samples, with alternating red and blue rows. Bytes | |
| 27 | are stored in memory in little endian order. They are conventionally | |
| 28 | described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example | |
| 88646d37 | 29 | of one of these formats: |

| 056d2ee6 | 31 | **Byte Order.** |
| 88646d37 SA |
32 | Each cell is one byte, the 4 most significant bits in the high bytes are |
| 33 | 0. | |
