Patent ID: 8125553

Claim:
An apparatus comprising; an array having a plurality of photosensitive cells that are arranged in a plurality of columns and a plurality of rows, wherein each column includes a set of photosensitive cell pairs that have a shared region with a share floating diffusion region and a shared selection transistor, and wherein the location of each shared region of each column is shifted by one row in each adjacent column; a plurality of storage elements, wherein each storage element is associated with at least one column; and row selection logic that is coupled to each shared selection transistor, wherein the row selection logic includes: a plurality shift registers that are arranged in a sequence, wherein each shift register is associated with at least one row, and wherein each shift register in the sequence is coupled to each adjacent shift register in the sequence; and a plurality combinational logic element, wherein each combinational logic element is coupled to a set of shared selection transistors and coupled to at least one shift register.
