Abstract
Provided is a solid-state imaging element configured to automatically extend dynamic range for each unit pixel. A solid-state imaging element includes, for a unit pixel, a first photoelectric conversion element, a first accumulation portion that accumulates electric charge obtained by photoelectric conversion by the first photoelectric conversion element, and a first film that is electrically connected to the first accumulation portion and has an optical characteristic changing according to applied voltage. Furthermore, the unit pixel of the solid-state imaging element can further include a first transfer transistor that transfers electric charge obtained by photoelectric conversion by the photoelectric conversion element to the first accumulation portion, an amplification transistor that is electrically connected to the first accumulation portion, and a selection transistor that is electrically connected to the amplification transistor.
