Abstract: An imaging device includes a readout unit which reads out an amount of charge accumulated in a floating diffusion that accumulates a charge transmitted from a light receiving unit that photoelectrically converts incident light as a signal level; a readout control unit which controls the readout unit to perform, a plurality of times, a readout operation to read out the amount of charge of a P-phase and a D-phase accumulated in the floating diffusion; and a calculation unit which is controlled by the readout control unit and obtains differences between the signal levels which are obtained using the readout operation that is performed a plurality of times.

Abstract: A solid-state imaging device includes: a pixel array unit with pixels, each of the pixels including a photoelectric conversion element that generates a charge and a memory that holds the charge; and an AD conversion unit that converts a pixel signal corresponding to the charge output from the pixel into a count value. The pixel transfers the charge held in the memory in the nth frame and sequentially outputs, in the nth+1 frame, a first pixel signal corresponding to the charge held in the memory and a second pixel signal corresponding to a charge generated by the photoelectric conversion element after the previous charge has been transferred to the memory. In the nth+1 frame, the AD conversion unit changes its up/down count direction between the first and second pixel signals to obtain their count values so as to successively perform AD conversion on the first and second pixel signals.
