The solid-state image pickup device includes: reset switches (13,23) for opening/closing between a VDDCELL that repeatedly and cyclically outputs a high potential and a low potential and an electric charge holding section in each pixel; reset signal lines (97,98) connected to pixels of the same row; a row scan circuit (80) for successively selecting rows, always giving Hi impedance or Lo impedance to the reset signal of the selected row and Hi impedance to the reset signal lines of the non-selected row; and an ALLRS circuit 94 for giving the Lo potential to the reset line of the non-selected row before and after the rise of VDCELL from a low potential to high potential. Thus, the solid-state image pickup device can reduce its size and increase its operation speed while suppressing lowering of the dynamic range.
