摘要： An object of the present invention is to provide a shift register in which it is prevented from malfunctioning because of a portion between a first transistor and a second transistor being in a high-impedance state. The shift register of the present invention includes capacitor means 5 for storing data outputted from a unit circuit 1 of the preceding block. A first transistor 3 is turned ON only when data is being stored in the capacitor means 5. A second transistor 7 includes a control electrode and an input-side diffusion layer connected to the output-side diffusion layer of the first transistor 3, and is turned ON only when a pulse of a clock signal from the first transistor 3 is inputted to the control electrode and the input-side diffusion layer. Potential controlling means 2 keeps the second transistor 7 OFF at least during a period in which the second transistor 7 is supposed to be OFF.

摘要： A solid-state image pickup device consists of a plurality of pixels arranged in a matrix for outputting an image signal corresponding to the received light intensity. 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.
