Patent ID: 8866059

Claim:
A solid-state imaging device including a plurality of pixel circuits two-dimensionally arranged on a semiconductor substrate, said solid-state imaging device comprising: a photoelectric conversion unit configured to generate a charge from incident light; a first transfer unit connected to said photoelectric conversion unit and configured to transfer the charge; a first accumulation unit configured to accumulate the charge via said first transfer unit; a second transfer unit connected to said first accumulation unit and connected in series to said first transfer unit; an output unit configured to output a signal voltage that is a voltage according to an amount of the charge via said second transfer unit; and a reset unit configured to set a voltage of a connection point between said second transfer unit and said output unit to a reset voltage, wherein said output unit is configured to output a reference voltage in a state where the reset voltage is applied to the connection point, said photoelectric conversion unit generates a first charge while the incident light enters said photoelectric conversion unit during a first accumulation time within a first frame period, said photoelectric conversion unit generates a second charge while the incident light enters said photoelectric conversion unit during a second accumulation time within the first frame period, the first accumulation time is different from the second accumulation time, the first transfer unit is configured to transfer the first charge and the second charge to the first accumulation unit, said first accumulation unit is configured to add and accumulate the first charge and the second charge, and only one picture is generated during the first frame period based on the first charge and the second charge accumulated by the first accumulation unit.
