  • Patent number: 11800256
    Abstract: In a solid-state image sensor that transfers electric charges to a floating diffusion layer, exposure is started before transferring the electric charges to the floating diffusion layer. A photodiode generates electric charges by photoelectric conversion. An electric charge accumulation unit accumulates electric charges. The floating diffusion layer converts electric charges into a signal level corresponding to the amount of the electric charges. An exposure end transfer transistor transfers the electric charges from the photodiode to the electric charge accumulation unit when a predetermined exposure period ends. A reset transistor initializes a voltage of the floating diffusion layer to a predetermined reset level when the exposure period ends. When a new exposure period is started after the electric charges are transferred to the electric charge accumulation unit, a discharge transistor discharges electric charges newly generated in the photodiode.
