Abstract:
An imaging device includes a pixel including a permittivity modulation element that includes opposite and pixel electrodes and a permittivity modulation structure whose permittivity changes according to the radiation of light, a capacitive element that includes first and second electrodes, and a detection circuit that outputs a signal corresponding to the potential of the pixel electrode. Also provided are a voltage supply circuit that applies first and second voltages in different first and second periods to one of the opposite electrode and the first electrode, and a signal processing circuit that generates a third signal being a difference between a first signal output from the detection circuit in the first period and a second signal output from the detection circuit in the second period. The potential difference between the opposite electrode and the first electrode when the second voltage is applied is less than when the first voltage is applied.
