<p>In a CCD type solid state image pickup device including two-dimensionally arranged photo/electro conversion portions (1), a plurality of vertical shift registers (2) each connected to one column of the photo/electro conversion portions, and a horziontal transfer portion (3) connected to the vertical shift register, signal charges (QA, QB, QC, QD or QC, QD, QE, QF) of every four of each column of the photo/electro conversion portions are mixed within the vertical shift registers or within the vertical transter portions and the horizontal output register, to create a mixed signal charge (QA + QB + QC + QD or Q C + QD + QE + QF). 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. <IMAGE></p> |
