Image pickup device and electronic apparatus

The present technology pertains to an imaging device and an electronic apparatus, each of which is capable of expanding the dynamic range without reducing the amount of saturated charge of a photodiode. A photoelectric conversion unit that converts light into electric charges, a plurality of storage sections that temporarily store the electric charges, a plurality of transfer units that transfer the electric charges to the storage sections, and a through trench that separates pixels are provided. At least one of the plurality of memory units is a capacitive element. At least one of the plurality of storage units stores the charge overflowed from the photoelectric conversion unit. This technology can be applied, for example, to an imaging device for capturing an image. 本技术涉及均能够在不降低光电二极管的饱和电荷量的情况下扩大动态范围的摄像器件和电子设备。提供了将光转换为电荷的光电转换单元、临时存储电荷的多个存储部、向存储部传输电荷的多个传输单元、以及分离像素的贯通沟槽。多个存储部中的至少一者是电容元件。多个存储部中的至少一者存储从光电转换单元溢出的电荷。例如，本技术可应用于用于拍摄图像的摄像器件。
