Patent ID: 7381940

Claim:
A light receiving element, comprising: a plurality of light receiving cells arranged in matrix each of which converts an incident light into an electric signal and has first and second electrodes whose polarities are different from each other, first to fourth output terminals, a first resistance unit including a plurality of resistors each having one end connected to said first electrode of said light receiving cell corresponding to the first column in the matrix of said light receiving cells and the other end connected to said first output terminal, a second resistance unit including a plurality of resistors each having one end connected to said first electrode of said light receiving cell corresponding to the last column in the matrix of said light receiving cells and the other end connected to said second output terminal, a third resistance unit including a plurality of resistors each having one end connected to said first electrode of said light receiving cell corresponding to the first row in the matrix of said light receiving cells and the other end connected to said third output terminal, a fourth resistance unit including a plurality of resistors each having one end connected to said first electrode of said light receiving cell corresponding to the last row in the matrix of said light receiving cells and the other end connected to said fourth output terminal, and a fifth resistance unit including a plurality of resistors which connect said first electrodes of said light receiving cells adjacent to each other in the matrix of said light receiving cells, wherein said second electrodes of said plurality of light receiving cells arranged in matrix are connected to a common potential.
