Reg Use
|
|
0x10 high nibble red gain low nibble blue gain
|
|
0x11 low nibble green gain
|
|
0x12 hstart
|
|
0x13 vstart

|
0x15 hsize (hsize = register-value * 16)
|
|
0x16 vsize (vsize = register-value * 16)
|
|
0x17 bit 0 toggle compression quality (according to sn9c102 driver)
|
|
0x18 bit 7 enables compression, bit 4-5 set image down scaling:
|
|
00 scale 1, 01 scale 1/2, 10, scale 1/4
|
|
0x19 high-nibble is sensor clock divider, changes exposure on sensors which
|
|
use a clock generated by the bridge. Some sensors have their own clock.
|
|
0x1c auto_exposure area (for avg_lum) startx (startx = register-value * 32)
|
|
0x1d auto_exposure area (for avg_lum) starty (starty = register-value * 32)
