Abstract

According to one embodiment, a solid-state imaging device includes an image sensor including a valid pixel area having valid pixels and a light-blocking pixel area having light-blocking pixels to generate an image signal; and a clamp circuit that detects an overflow of a signal charge and executes a black level signal processing for the image signal using a parameter. The clamp circuit detects the overflow using an integration value of the signals of the light-blocking pixels integrated in a direction from the light-blocking pixel area to the valid area, and sets the parameter generated from the output signals of the light-blocking pixels substantially not influenced by the overflow based on a result of the detection.
