According to one embodiment, there is provided an analog gain range determining unit that determines a range to which an analog gain setting an amplification factor of a pixel signal read from a pixel belongs, a clamp parameter control condition setting unit that sets a control condition of a clamp parameter setting the black level based on a result of the determination by the analog gain range determining unit, and a clamp parameter control unit that controls the clamp parameter based on the control condition set by the clamp parameter control condition setting unit.

Black level adjustment control device and solid-state imaging device

According to the embodiment, a feedback clamp circuit is included, which increases or decreases a clamp parameter so that a black level approaches a target value while controlling a change amount of the clamp parameter, which sets the black level, based on the black level read out from OB pixels.
