Patent ID: 6992341

Claim:
An amplifying solid-state image pickup device comprising: a plurality of photoelectric conversion transfer parts which are provided for individual pixels, respectively, and each of which has a photoelectric conversion element and at least one transfer transistor for transferring signal charge of the photoelectric conversion element, wherein the plurality of photoelectric conversion transfer parts are divided into a plurality of photoelectric conversion transfer part groups each composed of at least two of the photoelectric conversion transfer parts, respectively; a plurality of switched capacitor amplification parts which are provided for the individual photoelectric conversion transfer part groups, respectively, of which input side of each is connected to an output side of each transfer transistor of the photoelectric conversion transfer parts and of which output side of each is connected to a signal line; and a control part for selecting a plurality of photoelectric conversion transfer parts out of all the photoelectric conversion transfer parts within the photoelectric conversion transfer part group, and controlling the transfer transistors and the switched capacitor amplification parts so that signal charges of the photoelectric conversion elements of the selected plurality of photoelectric conversion transfer parts are transferred to the input side of the switched capacitor amplification part via the transfer transistors of the selected plurality of photoelectric conversion transfer parts, the plurality of signal charges are added up, and the added-up signal charge is read out by the switched capacitor amplification parts.
