A solid-state imaging device including a plurality of photoelectric conversion elements (for example, photodiodes) arranged on a semiconductor substrate so as to form a matrix and read-out means for reading out signal charges which are stored in the photodiodes in accordance with incident light, in a predetermined order, is disclosed in which device the read-out means is made up of a plurality of active elements such as a MOS transistor connected to a photodiode, part of the active elements are used as a pixel amplifier for amplifying the signal charge of the photodiode in such a manner that the signal charge is converted into a current or voltage, the output of the pixel amplifier at a time the signal charge of the photodiode is not applied to the input part of the pixel amplifier and the output of the pixel amplifier at a time the signal charge of the photodiode is applied to the input part of the pixel amplifier are separately stored in a pair of storage means, and the outputs of a plurality of pairs of storage means are successively taken out in accordance with a scanning signal.
