Claim:
1. An imaging device comprising: a plurality of pixels, each including wherein the electrical connection of the capacitor to the floating diffusion is switched to vary a capacitance value of an input node of the amplifier transistor, wherein each of the plurality of pixels has an active region including a first region and a second region, the first region and the second region being arranged with the electrode therebetween in plan view, wherein a portion that is a portion of the active region and that is located under the electrode forms at least a portion of the capacitor, wherein the first region includes a first semiconductor region of a first conductivity type, the first semiconductor region forming at least a portion of the floating diffusion, wherein the second region includes a second semiconductor region of a second conductivity type opposite to the first conductivity type, and wherein an insulating film is disposed on the second semiconductor region.
