| 5 | MIME-Version: 1.0 |

| 9 | Use the correct register (Yn_01) with first half of the |
| 10 | Y samples instead of using the register (Yn_23) with the |
| 11 | second half twice when computing the green channel. |
| 12 | |
| 13 | Also use the Yn_01 register name instead of Yn for the red |
| 14 | channel as well, just for a bit of extra consistency. |
