1 Register 87 & 88
Signed 12 bit value (0..4095) for even/odd rows:
max offset: 2047 min offset: 2048
Default value:780
From the datasheet:
The value in this register defines the dark level offset applied to the bottom/top output signal (min = 0, max = 4095)
1824: 12 bits per pixel 533: 10 bits per pixel 600: 8 bits per pixel
Using a higher offset shifts in the black coloumns (in this example 1980 was used as offset value for both top/bottom rows):
2 Register 102
from Application Note:
Lowering reg 102 [6:0] will reduce the spatial row noise, but will also decrease the black sun protection. When the protection is set to the default value of 120, it can influence the CDS working, causing increased FPN in the image. You should find a trade-off between the protection and the FPN. We see that a value of 100 should be OK for most applications.
Datasheet lists this register as "DO NOT CHANGE" with default value of "8312"
