Abstract:
1. A solid state imaging device comprising: a plurality of unit pixels including an intermediate charge transfer unit configured to transfer, to said charge holding region, a first signal charge, which exceeds a predetermined charge amount, generated at said photoelectric converter in an exposure period in which all of said plurality of unit pixels perform imaging operations at the same time; and a pixel driving unit configured to, during the exposure period in which all of said plurality of unit pixels perform imaging operations at the same time, set said first transfer gate to a non-conducting state, set said second transfer gate to a conducting state, transfer said first signal charge from said charge holding region to said floating diffusion region, set said second transfer gate to a non-conducting state, set said first transfer gate to a conducting state, and transfer the charge accumulated in said photoelectric converter to said charge holding region as a second signal charge, wherein,
