| 12-bit Packed Bayer formats. |
| |
| Description |
| =========== |
| |
| These four pixel formats are used by Mediatek ISP P1. |
| This is a packed format, meaning all the data bits for a pixel lying |
| next to each other with no padding in memory, with a depth of 12 bits per pixel. |
| The least significant byte is stored at lower memory addresses (little-endian). |
| The RGB byte order follows raw sRGB / Bayer format from sensor. |
| They are conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. |
| Below is an example of conventional RGB byte order BGGR. |
| |
| **Byte Order.** |
| Each cell is one byte. |
| |
| pixels cross the byte boundary and have a ratio of 6 bytes for each 4 pixels. |
