PROBLEM TO BE SOLVED: To provide a solid-state imaging device capable of reducing a margin without depending on a variation between and among pixels, improving the accuracy of determination associated with the occurrence of a black level depression phenomenon, and suppressing the lowering of a dynamic range. SOLUTION: A difference circuit 29 performs difference processing on a reset signal or a pixel signal after initializing a charge retention unit and an optical signal or a pixel signal after transferring a signal charge to the charge retention unit for each pixel. A variation detection circuit 25 detects a variation value in a reset signal for each pixel. A correction determining circuit 28 compares the variation value with a predetermined threshold.
