Abstract
In a solid state image pickup apparatus comprising a solid state image pickup device (1) which has an image pickup surface composed of a plurality of image pickup picture units (E.sub.11 -E.sub.mn), each of which contains a first switching element (S.sub.11, S.sub.12, . . . S.sub.mn) and a photoelectric converter (D.sub.11, D.sub.12, . . . D.sub.mn) electrically connected to the first switching element, and which are disposed in a predetermined arrangement and second switching elements (T.sub.1 -T.sub.n) connected to the image pickup picture units (E.sub.11 -E.sub.mn) and vertical and horizontal scanning circuits (13:14) for driving the first and second switching elements (S.sub.11 -S.sub.mn :T.sub.1 -T.sub.n), the vertical and horizontal scanning circuits (13:14) are made operative in a stable state to cause the first and second switching elements (S.sub.11 -S.sub.mn :T.sub.1 -T.sub.n) to be continuously closed before a charge storage period in which signal charge is stored in the image pickup picture units (E.sub.11 -E.sub.mn) and also made operative in a pulse generating state to cause the first and second switching elements (S.sub.11 -S.sub.mn :T.sub.1 -T.sub.n) to be selective…
