Solid state image pickup apparatus
First Claim
1. A solid state image pickup apparatus comprising an image pickup surface composed of a plurality of image pickup picture units each of which contains a switching device and a photoelectric converter arranged in a matrix of horizontal rows and vertical columns, a shutter which is periodically opened and closed to simultaneously supply light to all of said photoelectric converters, a vertical switch control with a plurality of outputs each respectively connected to sequentially turn on the switching elements of common horizontal rows after said shutter has been opened and closed, a plurality of horizontal switch means respectively connected to said columns of switching devices, a horizontal switch control connected to said plurality of horizontal switch means to sequentially switch them on after said shutter has opened and closed to remove the image charges and said vertical and horizontal switch controls supplying signals to render all of said switching devices of said image pickup picture units and said plurality of horizontal switch means conductive during the period after said image charges have been shifted out until said shutter is openend and renders them non-conductive when said shutter is open.

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 (E11 -Emn), each of which contains a first switching element (S11, S12, . . . Smn) and a photoelectric converter (D11, D12, . . . Dmn) electrically connected to the first switching element, and which are disposed in a predetermined arrangement and second switching elements (T1 -Tn) connected to the image pickup picture units (E11 -Emn) and vertical and horizontal scanning circuits (13:14) for driving the first and second switching elements (S11 -Smn :T1 -Tn), the vertical and horizontal scanning circuits (13:14) are made operative in a stable state to cause the first and second switching elements (S11 -Smn :T1 -Tn) to be continuously closed before a charge storage period in which signal charge is stored in the image pickup picture units (E11 -Emn) and also made operative in a pulse generating state to cause the first and second switching elements (S11 -Smn :T1 -Tn) to be selectively closed in a predetermined period after the charge storage period.
