    摘要: Conventionally, in order to obtain a difference signal between an A+N signal and an N signal and a difference signal between an A+B+N signal and the A+N signal, the A+N signal needs to be held in two different capacitors. Hence, there is a problem in that, due to variations in capacitance of the two capacitors, the difference signal between the A+N signal and the N signal and the difference signal between the A+B+N signal and the A+N signal may not accurately be obtained. An imaging device generates a signal obtained by subtracting the same digital N signal from each of the digital A+N signal and the digital A+B+N signal.
