26 | 0x10 high nibble red gain low nibble blue gain | |
27 | 0x11 low nibble green gain | |
28 | 0x12 hstart | |
29 | 0x13 vstart | |

31 | 0x16 vsize (vsize = register-value * 16) | |
32 | 0x17 bit 0 toggle compression quality (according to sn9c102 driver) | |
33 | 0x18 bit 7 enables compression, bit 4-5 set image down scaling: | |
34 | 00 scale 1, 01 scale 1/2, 10, scale 1/4 | |
35 | 0x19 high-nibble is sensor clock divider, changes exposure on sensors which | |
36 | use a clock generated by the bridge. Some sensors have their own clock. | |
37 | 0x1c auto_exposure area (for avg_lum) startx (startx = register-value * 32) | |
