Abstract: According to the present disclosure, an imaging element may include: a substrate or a well; a pinned photodiode disposed on the substrate; a floating diffusion region disposed on the substrate or the well; a first transfer gate transistor disposed between the pinned photodiode and the floating diffusion region a photodiode signal charge generated by the pinned photodiode to the floating diffusion region; one or more gate-controlled storages disposed on the substrate and storing a signal charge generated by the pinned photodiode as a storage signal charge; a storage-controlling gate electrode disposed adjacent to the gate-controlled storage; an overflow path disposed between the pinned photodiode and the gate-controlled storage and transferring the storage signal charge from the pinned photodiode to the gate-controlled storage; and a detecting node connected to the floating diffusion region, wherein the photodiode signal charge and the storage signal charge can be read at the detecting node.
