Abstract
A solid state image pickup device comprises a plurality of image pickup picture units (E.sub.11 to E.sub.mn) arrayed in horizontal and vertical rows and composed of first switching elements (S.sub.11 to S.sub.mn) and photoelectric transducers (D.sub.11 to D.sub.mn : 24) electrically connected to the first switching elements (S.sub.11 to S.sub.mn), and a plurality of second switching elements (T'.sub.1 to T'.sub.n) connected in common to the respective vertical rows of the first switching elements (S.sub.11 to S.sub.mn) in the image pickup picture units (E.sub.11 to E.sub.mn) and each composed of a depletion-mode insulated-gate field-effect transistors. The horizontal rows of the first switching elements (S.sub.11 to S.sub.mn) in the image pickup picture units (E.sub.11 to E.sub.mn) are selectively energizable and the second switching elements (T'.sub.1 to T'.sub.n) are also selectively energizable to deliver signals based on signal charge generated by the photoelectric transducers (D.sub.11 to D.sub.mn : 24) through the first and second switching elements (S.sub.11 to S.sub.mn, T'.sub.1 to T'.sub.n) so as to produce an image pickup signal output.
