Abstract
An image sensor device includes a photoelectric conversion element configured to receive incident light and generate photocharges in response to the received incident light; a floating diffusion coupled to the photoelectric conversion element to store the photocharges generated by the photoelectric conversion element, the floating diffusion having a first capacitance value; a conductive pattern electrically coupled to the floating diffusion; and a variable electrode located apart from the conductive pattern by a gap, wherein the conductive pattern and the variable electrode form a variable capacitor coupled to the floating diffusion and having a second capacitance value and operable to change an effective capacitance of the floating diffusion in response to a control signal applied to the variable electrode.
