In a solid state color imaging system comprising a two-dimensional array of photoelectric devices, the photoelectric device in one of two adjacent rows are displaced with respect to those in the other row in the horizontal direction by half a horizontal pitch of the photoelectric devices, and the respective color filter elements associated with three photoelectric devices adjacent to one another in the two rows have such spectrum characteristics that the sum of outputs from the three photoelectric devices substantially corresponds to a luminance signal, whereby Moire is suppressed and high quality color pictures are obtained.
