The present invention provides a solid-state image pickup device having a little operation timing shift of pixels and being capable of obtaining a sensor output of a high SN ratio. A solid-state image pickup device includes a photoelectric conversion pixel unit 1 composed of a plurality of arranged pixels each equipped with at least a photoelectric conversion unit and a transistor for amplifying and outputting a signal from the photoelectric conversion unit, and memory units 9 and 10 each composed of arranged analog memory cells corresponding to at least a part of pixels of the photoelectric conversion pixel unit 1, wherein the device includes a plurality of coupling capacitors 5 connected to a plurality of output lines, respectively, to each of which the pixels arranged in a column are commonly connected, for reducting noises of the pixels by clamping signals from the pixels; a plurality of amplifiers 24 each connected to the plurality of coupling capacitors 5 for amplifying a signal voltages from the coupling capacitors 5; and circuit means 25, 26, 27 and 28 each connected to the plurality of amplifiers 24 for outputting the output offset and an amplified signal of each of the amplifiers 24. <IMAGE> |
