There is provided a solid-state imaging element capable of performing AD conversion on pixel signals in a wide dynamic range in a short time.
A solid-state imaging device according to the present disclosure includes: a pixel section including photoelectric conversion elements that photoelectrically convert incident light into pixel signals; an AD conversion section that converts the pixel signals from the pixel section into digital signals; a first holding circuit that is provided between the pixel section and the AD conversion section and holds the pixel signals; a second holding circuit that is provided between the pixel section and the AD conversion section and holds the pixel signals; and a selection circuit that is capable of connecting any one of the first and second holding circuits to the AD conversion section and selectively transmits the pixel signals held in the first or second holding circuit to the AD conversion section.
