| 12-bit Bayer formats expanded to 16 bits |
| |
| |
| Description |
| =========== |
| |
| These four pixel formats are raw sRGB / Bayer formats with 12 bits per |
| colour. Each colour component is stored in a 16-bit word, with 4 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_SBGGR12 image: |
| |
| **Byte Order.** |
| Each cell is one byte, the 4 most significant bits in the high bytes are |
| 0. |
