Abstract
According to one embodiment, there is provided a signal processing device that processes a signal output from an imaging sensor. The device includes a lead integration unit, a main integration unit, and a correction unit. The lead integration unit integrates and averages, in a first integration region, signals of a plurality of first light-shielded pixels in a light-shielded area. The main integration unit integrates and averages, in a second integration region that is determined based on a result integrated and averaged by the lead integration unit, signals of a plurality of second light-shielded pixels in the light-shielded area. The correction unit determines a reference black level based on a result integrated and averaged by the main integration unit and corrects a black level of a signal of a light receiving pixel using the determined reference black level.
