Because extremely bright image like sun affects reset data voltage of pixel to lower, bright image
is captured as black image in image sensor regardless of correlated double sampling. To solve this
extraordinary phenomenon, we adopt the method to clamp reset data voltage. Reset Level Clamp
controls the reset data voltage to prevent inversion of extremely bright image. The larger register
value clamps the reset data level at highest voltage level. Default value is 7 to clamp the reset
data level at appropriate voltage level.

Auto black level compensation
Each sensor has little different photo-diode characteristics so that the sensor provides internal
adjustment registers that calibrates internal sensing circuit in order to get optimal performance.
Sensor characteristics adjustment registers are as below.
