Abstract
A solid-state imaging device includes a pixel circuit that outputs a plurality of pixel signals, a detection circuit, and a signal processor. The pixel circuit includes a photodiode, a transfer transistor that reads out a signal of the photodiode to a charge storage, and a storage capacitance that stores a charge overflowing from the photodiode. The detection circuit compares a signal of the storage capacitance with a reference signal and, when the signal of the storage capacitance has reached the reference signal, initializes the photodiode and the storage capacitance and counts an initialization count. The signal processor calculates a first signal that indicates intensity of incident light, in accordance with the initialization count and a mixed signal of the signal of the storage capacitance and the signal of the photodiode that has been read out to the charge storage by the transfer transistor.
