Abstract:
1. A solid state image pickup device comprising a plurality of unit pixels in a matrix shape, in which each of said unit pixels comprises: a photoelectric conversion unit where carriers are generated by incident light; a transfer unit adapted to transfer the carriers; a floating diffusion region where the carriers are transferred by said transfer unit; a carrier holding unit adapted to accumulate the carriers overflowed from said photoelectric conversion unit; and an output unit adapted to output a signal corresponding to the carriers transferred to said floating diffusion region, wherein one of said carrier holding unit and said output unit is provided between the photoelectric conversion unit included in the first pixel and the photoelectric conversion unit included in the second pixel adjacent to the first pixel in the row direction, the other one of said carrier holding unit and said output unit is provided between the photoelectric conversion unit included in the first pixel and the photoelectric conversion unit included in the third pixel adjacent to the first pixel in the column direction.
