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.

Abstract: An image sensor may include: an active pixel region in which a plurality of active pixels are arranged; and one or more optical black regions positioned adjacent to the active pixel region, and each including a first region in which a plurality of first pixels are arranged and a second region in which a plurality of second pixels having a different pixel size from the first pixels are arranged.

Abstract: An image sensor is described. The image sensor includes a photodiode that is formed in a substrate, a floating diffusion region that vertically overlaps with a first portion of the photodiode, a shallow trench isolation (STI) region that vertically overlaps with a second portion of the photodiode and has an elbow shape, and a transfer gate that is adjacent to at least two sides of the photodiode and has an elbow shape.
