These registers control the offset voltage of ADC that changes the black level value for active pixels,
red, green and blue pixel respectively. The registers are internally updated by black level
compensation logic, and are read-only registers. Register bit functions are composed as follows.
The bit specifies whether to subtract or add offset voltage in ADC input for

active pixels.

This value specifies the amount of offset voltage for active pixels.

The register specifies the maximum value which determines whether light-shielded pixel output is valid.
When light-shielded pixel output exceeds this limit, the pixel is not accounted for black level
calculation.
