Second Black Level
This register contains the value subtracted by IFP from pixel values prior to CCM. If the subtraction produces a
negative result for a particular pixel, the value of this pixel is set to “0.”

First Black Level
This register contains the value subtracted by IFP from raw pixel values before applying lens shading correction
and digital gains. If the subtraction produces a negative result for a particular pixel, the value of this pixel is set
to “0.” Typically, the subtracted value should be equal to the black level targeted by the sensor. This value is
subtracted from all test patterns as well.
