1. An imaging device, comprising:
a photoelectric conversion element provided in each of a plurality of pixels;
a first charge accumulation section connected to the photoelectric conversion element;
a second charge accumulation section connected in parallel with the first charge accumulation section;
a reset transistor configured to reset a potential of the second charge accumulation section;
a transfer transistor disposed between the first charge accumulation section and the second charge accumulation section;
a third charge accumulation section connected in parallel with the first charge accumulation section; and
a first changeover switch that is disposed between the first charge accumulation section and the third charge accumulation section and switches whether or not to connect the third charge accumulation section to the photoelectric conversion element.
