Abstract: In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparsity than that of an image signal.
