Abstract: Each solid image pick-up element of G, R and B channels has a light-receiving portion composed of light-receiving pixels arranged two-dimensionally, that is, in the horizontal and the vertical scanning directions. The light-receiving pixels of the second and the third solid image pick-up elements are shifted to a horizontal direction by a half of a horizontal interval between the adjacent pixels with respect to the light-receiving pixels of the first solid image pick-up element in the horizontal scanning direction. The output of the first solid image pick-up element is sampled at every predetermined period so that the video signal of the G channel is obtained. The output of the second and the third solid image pick-up elements are sampled at every predetermined period to obtain the video signals of the R and the B channels so that the video signals are out of phase by 180 degrees with respect to the video signal of the G channel.
