Patent ID: 8456546

Claim:
A solid-state imaging device comprising: a pixel array unit in which unit pixels including photoelectric conversion elements for converting light signals into signal charges are arranged in a matrix; and a signal processing circuit that obtains a first video signal at a first sensitivity and a second video signal at a second sensitivity and performs processing for combining the first and second video signals, wherein the signal processing circuit includes: judging means for comparing a level of a luminance value of the first video signal and a level of a luminance value of the second video signal of a pixel of interest in the pixel array unit with respect to a reference luminance value to thereby judge whether the pixel of interest is a pixel to be saturated during an exposure period; calculating means for setting the pixel of interest, which is judged by the judging means as the pixel to be saturated, as a correction pixel and calculating 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 for applying the correction amount calculated by the calculating means 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, wherein the calculating means subtracts the reference luminance value from the luminance value of the second video signal of the peripheral pixel and sets a value obtained by multiplying a result of the subtraction with a correction coefficient as the correction amount, wherein there is a plurality of peripheral pixels, and the calculating means subtracts, for each respective peripheral pixel of the plurality of peripheral pixels, the reference luminance value from luminance values of the second video signal of the plurality of peripheral pixels, calculates values obtained by multiplying results of the subtraction with a correction coefficient, and sets a sum of the values as the correction amount.
