ABSTRACT:
In a CCD type solid state image pickup device including two-dimensionally arranged photo/electro conversion portions, a plurality of vertical shift registers each connected to one column of the photo/electro conversion portions, and a horizontal transfer portion connected to the vertical shift register, signal charges of every four of each column of the photo/electro conversion portions are mixed within the vertical shift registers or within the vertical transfer portions and the horizontal output register, to create a mixed signal charge. Then, the mixed signal charge corresponding to four of the photo/electro conversion portions is transferred within the horizontal output register. Thus, one scanning line is formed by every four rows of the photo/electro conversion portions.
