Patent ID: 8390036

Claim:
An image pickup device comprising: a plurality of first electrodes that is arranged on an upper side of a substrate in two dimensions with a predetermined gap interposed between one of the first electrodes and another first electrode adjacent to the one of the first electrode; a second electrode that is arranged next to the first electrodes arranged on an outermost side of the first electrodes with the predetermined gap interposed between the first electrodes arranged on the outermost side and the second electrode; a third electrode that faces both of the plurality of first electrodes and the second electrode; a photoelectric conversion layer that is disposed between the plurality of first electrodes and the second electrode and the third electrode; a plurality of signal reading portions that is connected to the plurality of first electrodes and reads out signals corresponding to electric charge that is generated in the photoelectric conversion layer and moved to the plurality of first electrodes; and at least one electric potential adjusting portion that is connected to the second electrode and adjusts electric potential of the second electrode such that the electric potential of the second electrode determined in accordance with electric charge that is generated in the photoelectric conversion layer and moved to the second electrode is not beyond a predetermined range.
