A solid state image sensing device comprising a matrix-disposed photoelectric diodes 27+21, 27+21, . . . . on a monolithic substrate, wherein each one transferring switching means 24, . . . . and each one noise eliminating MOS switch 26, . . . . are provided for each vertical column of said matrix-disposed photoelectric transducing element, and the transferring switches 24, . . . . twice transfers information on a connecting line 22 of each column to a node point N.sub.ST during each horizontal fly-back period, so that the first one of said twice transferring transfers noise signal to the node points N.sub.ST for throwing it away, and the second one of said transferring transfers genuine light information of the photodiode 27, . . . to the node points N.sub.ST, . . . . for outputting the light information, whereby noises such as spurious noise, fixed pattern noise and blooming are eliminated and also scanning speed is improved.

Solid state image sensing device

Solid state imaging device wherein a plurality of picture elements each comprising a MOSFET and a photodiode connected to a source electrode of the MOSFET are arranged in rows and columns. The gate electrodes of the MOSFET in each row are connected in common, the drain electrodes in odd numbered rows and the drain electrodes in even numbered rows are connected in common, respectively within each column and connected to source electrodes of first and second switching MOSFET, respectively, arranged for each column. Drawn electrodes of the first switching MOSFET and drain electrodes of the second switching MOSFET are connected to first and second output lines, respectively, which are connected to input terminals of a differential amplifier. Photo spurious signals sensed at the drain regions of the MOSFET of the picture elements and noise spikes caused by gatedrain capacitances of the switching MOSFET are eliminated, amd the scanning speed is increased.
