Patent ID: 8836834

Claim:
An image sensing apparatus having a plurality of unit cells arranged in two dimensions, each unit cell including a plurality of photoelectric conversion elements, a common amplifier element shared by the plurality of photoelectric conversion elements, a reset element for resetting a potential of an input portion of the common amplifier element, and a plurality of transfer switches arranged respectively with the plurality of photoelectric conversion elements for transferring charge generated by each photoelectric conversion element to the input portion of the common amplifier element, wherein the common amplifier element and the reset element are arranged on the opposite sides of each photoelectric conversion element, and each photoelectric conversion element is arranged on a line between the common amplifier element and the reset element, wherein the common amplifier element of each unit cell is arranged in an area between the plurality of photoelectric conversion elements arranged adjacent each other in a first direction, wherein the reset element is arranged in an area between photoelectric conversion elements where the common amplifier element is not arranged, wherein intervals between centers of mass of photo-receiving areas of photoelectric conversion elements, immediately adjoining to each other in the first direction, are substantially equal in distance within and between all of the plurality of unit cells, and wherein the common amplifier element and the reset element are not arranged in an area between photoelectric conversion elements adjacent each other in a second direction which is different from the first direction.
