Patent attributes
A solid state imaging system includes a plurality of amplifying units that are placed one by one for every pair of photoelectric conversion areas. Each amplifying unit is placed side-by-side in one direction of a two-dimensional matrix for outputting a pixel signal according to a photogenerated charge retained in a floating diffusion area. A plurality of transfer controlling elements are placed in pairs for each pair of the photoelectric conversion areas for controlling the transfer of the photogenerated charge by changing a potential barrier of a photogenerated charge transfer route between each of the accumulation wells in the pair of photoelectric conversion areas and the corresponding floating diffusion area. A plurality of transfer gate lines are connected to each of the transfer controlling elements in the plural photoelectric conversion areas that are aligned in the other direction of the two-dimensional matrix.
