1. An imaging device comprising:
a photoelectric converter that converts incident light into a signal charge;
a node to which the signal charge is input;
a transistor having a source and a drain, one of the source and the drain being connected to the node; and
a capacitive element including a first electrode, a second electrode and a dielectric film sandwiched between the first electrode and the second electrode, the first electrode being connected to the other of the source and the drain of the transistor, the second electrode being connected to a voltage source or a ground, wherein
the transistor is configured to switch a first mode and a second mode, a sensitivity in the first mode being different from a sensitivity in the second mode.
