Patent ID: 7317214

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 a 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 a specified number of the photoelectric conversion transfer parts, respectively; and wherein the photoelectric conversion transfer part groups are arrayed in a matrix shape, and further comprising: a plurality of switched capacitor amplification parts which are provided for the individual photoelectric conversion transfer part groups, respectively, whose input side is connected to an output side of each transfer transistor of the photoelectric conversion transfer parts and whose output side is connected to a signal line; and a control part for, in each of the photoelectric conversion transfer part groups, controlling the transfer transistor and the switched capacitor amplification parts so as to iterate an operation of reading a signal from the photoelectric conversion element via the transfer transistor for the individual photoelectric conversion transfer parts, respectively, by the switched capacitor amplification part.
