Claim:
A solid-state image pickup device, comprising: a pixel array unit in which unit pixels are arranged two-dimensionally in matrix, each unit pixel including (a) a photoelectric conversion part that accumulates a charge generated by electric conversion, (b) a first transfer structure that transfers said charge from said photoelectric conversion part to a first charge accumulation portion, (c) a second transfer structure that transfers said charge from said first charge accumulation portion to a second charge accumulation portion, (d) a readout structure that reads out a signal in response to said charge to a signal line and (e) a reset structure that resets said second charge accumulation portion; and a row driving unit driving said unit pixel, wherein, (1) row driving unit is configured such that (a) said first transfer structure transfers said charge stored in said photoelectric conversion part during a first accumulation period to said first charge accumulation portion, (b) said second transfer structure and said readout structure read out a first signal to said signal line in response to said charge of said first charge accumulation portion, and then (c) said first transfer structure, said second transfer structure, and said readout structure read out a second signal to said signal line in response to said charge of said photoelectric conversion part during a second accumulation period, (2) light is incident on said photoelectric conversion part through a mechanical shutter, (3) said row driving unit resets said photoelectric conversion parts of all of said unit pixels simultaneously in an open state of said mechanical shutter, (4) said first transfer structure transfers said charges of said photoelectric conversion parts to said first charge accumulation portions in all of said unit pixels simultaneously, (5) said unit pixels in said pixel array unit are selected from each row in order in a close state of said mechanical shutter, (6) said first signal is read to said signal line by said second transfer structure and said readout structure, and (7) said second signal is read to said signal line by said first transfer structure, said second transfer structure, and said readout structure, while scanning.
