Abstract
Provided are a solid-state imaging device, a method for driving a solid-state imaging device, and an electronic apparatus capable of providing characteristics of high gain and low noise as much as possible in a configuration that can detect stored signals during the integration period. A pixel includes a first transient gate PG formed between a floating diffusion FD and a photodiode PD and capable of controlling a charge transfer path CTP between the FD and the PD. The FD and the PD are coupled by the first transient gate PG, and photocharges generated by the PD are transferred immediately to the FD.
