Abstract
A solid-state imaging device includes a pixel array unit in which unit pixels are arranged in a matrix shape and a signal processing circuit that obtains a first video signal and performs processing for combining the first and second video signals. The signal processing circuit includes judging means that judges whether a pixel of interest in the pixel array unit is a pixel to be saturated during an exposure period, calculating means that sets the pixel of interest as a correction pixel and calculates a correction amount on the basis of a luminance value of the second video signal of a peripheral pixel of the correction pixel, and correcting means that applies the correction amount to a luminance value of the first video signal of the correction pixel to thereby correct a noise signal amount due to photo-charges leaking from the peripheral pixel into the correction pixel.
