摘要： A method of manufacturing a "two-level" solid-state image pickup device wherein a portion of a first metallic electrode electrically connected to a signal storage region is made to project to the highest position above a substrate on which it is formed. A coating of an organic insulating film is then applied to produce a flat surface. The entire surface of the organic film is then etched to expose the projections of the first metallic electrode. A second metallic electrode constituting a pixel electrode is connected to the first electrode at the exposed portion thereof.

摘要： In an image sensing system, a solid-state image sensor is mounted on a vibration stand in a manner as to vibrate horizontally to an incoming light in synchronization with one frame period, thereby sensing while alternatively displacing at different sampling positions in two field periods. Field image signals from the image sensor is supplied, through a signal processor, to a signal reproduction unit which includes a carrier generator for producing first and second carrier signals having the same frequency as the horizontal readout frequency of the image sensor and a phase in reverse to one other in the field periods, and an AM modulator for amplitude-modulating the carrier signal. The amplitude modulation field signals thus obtained are sliced at a suitable level by a slicer and then synthesized each other to obtain a frame image signal.

摘要： A solid state image-sensing device which comprises an image-sensing area formed of a plurality of matrix-arranged cells exposed to an introduced image light and an optical black connected to a readout section in parallel relationship with the image-sensing area. An image light is prevented from entering the optical black. Only noise charges (dark current charges) sent forth from the optical black are transferred to a control circuit. A gate electrode control signal for eliminating charges whose amount corresponds to that of the noise charges from the total charges collected in the storage regions of the matrix-arranged cells of the image-sensing area is produced by a control circuit. The gate electrode control signal is supplied to a gate electrode positioned between the photosensing section and vertical transfer section of the cells of the image-sensing area. A potential well lying under the gate electrode has its depth controlled by the gate electrode control signal. At first, a charge whose amount is substantially equal to that of a light-generated signal charge stored in the storage region of the image-sensing area is transferred to a vertical transfer section. After elimination of the noise charges, the remaining charges are returned at least once to the photosensing sections of the respective cells to be held in the storage regions of the photosensing sections of the cells for a prescribed length of time.
