Claim:
A solid-state image pickup device comprising on a semiconductor substrate: a plurality of photodiodes that are disposed in a matrix (i, j) to convert light beams into signal charges and accumulate the signal charges; an electric charge transfer transistor for reading out the signal charges accumulated in the photodiodes; a floating diffusion for converting into electric potentials the signal charges that are photoelectrically converted by the photodiodes and are read out by the electric charge transfer transistor; a reset transistor for resetting the signal charges; and an amplifier transistor for amplifying the read out signal charges, the reset transistor and the amplifier transistor being shared by the plurality of photodiodes, a distance d 1 between a center of gravity of a region for sensing the light beams in a photodiode (i, j) and a center of gravity of a region for sensing the light beams in a photodiode (i, j+1) being different from a distance d 2 between a center of gravity of a region for sensing the light beams in a photodiode (i+1, j) and a center of gravity of a region for sensing the light beams in a photodiode (i+1, j+1), and a distance d 3 between the center of gravity of the region for sensing the light beams in the photodiode (i, j+1) and a center of gravity of a region for sensing the light beams in a photodiode (i, j+2) being equal to the distance d 2 , wherein each of the photodiodes has a side close to the transfer transistor is longer than a side opposite thereto, and wherein each of the photodiodes is provided with a large number of vertices on a side disposed in a direction perpendicular to the side close to the transfer transistor, the side disposed in the direction perpendicular to the side close to the transfer transistor connecting the side close to the transfer transistor and the side opposite thereto.
