Imaging element and electronic apparatus

An imaging element, comprising:

• a photoelectric conversion section;
• a transfer transistor connected to the photoelectric conversion section;
• a floating diffusion connected to the transfer transistor;
• a first conversion efficiency switching transistor connected to the floating diffusion;
• a second conversion efficiency switching transistor connected to the first conversion efficiency switching transistor;
• a reset transistor connected to the second conversion efficiency switching transistor;
• a first accumulation section;
• and
• a second accumulation section,
• wherein the first accumulation section is connected between the first conversion efficiency switching transistor and the second conversion efficiency switching transistor,
• the second accumulation section is connected between the second conversion efficiency switching transistor and the reset transistor, and
• the floating diffusion accumulates a charge that has overflowed from the photoelectric conversion section.

An electronic apparatus, comprising:

• an imaging element including
• a photoelectric conversion section configured to convert light into a charge,
• three or more accumulation sections configured to temporarily accumulate the charge,
• a transfer section configured to transfer the charge from the photoelectric conversion section to the accumulation sections,
• a conversion efficiency switching section configured to control a conduction state between the accumulation sections,
• at least two accumulation sections of the three or more accumulation sections are each a capacitive element, and
• the three or more accumulation sections each accumulating an overflow charge from the photoelectric conversion section;
• and
• a processing unit configured to process a signal from the imaging element.
