| 12-bit packed Bayer formats |
| --------------------------- |
| |
| |
| Description |
| =========== |
| |
| These four pixel formats are packed raw sRGB / Bayer formats with 12 |
| bits per colour. Every two consecutive samples are packed into three |
| bytes. Each of the first two bytes contain the 8 high order bits of |
| the pixels, and the third byte contains the four least significants |
| bits of each pixel, in the same order. |
| |
| Each n-pixel row contains n/2 green samples and n/2 blue or red |
| samples, with alternating green-red and green-blue rows. They are |
| conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. |
| Below is an example of a small V4L2_PIX_FMT_SBGGR12P image: |

| **Byte Order.** |
| Each cell is one byte. |
