These registers control the offset voltage of ADC that changes the black level value for light-
shielded pixels, R,G,and B respectively. Register bit functions are composed as follows.
The bit specifies whether to subtract or add the offset voltage in ADC input
for light-shielded pixels.

These registers represent black level average offset values for light-shielded pixels R,G,B or
updated active offset values for R,G,B, respectively. What values are monitored is decided by
Pixel Black Offset[7]
This value specifies the amount of offset voltage for light-shielded pixels.
