摘要： In each pixel of a MOS-type solid-state imaging device, a plurality of first signals and one or more second signals are accumulated in a plurality of storage areas in a storage unit during driving. Here, each of the plurality of first signals corresponds to a light receiving signal (light receiving signal on which noise is superimposed) which is transmitted from a light receiving unit each time a switching unit is in a closed state, and each of the one or more second signals is a signal (noise such as dark-current noise, fixed pattern noise, and the like) as a voltage of a signal readout path when the switching unit is in an open state. Also, in the solid-state imaging device of the present invention, each of the one or more second signals in the storage unit of each image pixel is in a state of being physically or temporally separated from each of the plurality of first signals.
