摘要： A solid-state image pickup device has a plurality of photoelectric conversion elements arranged in a two-dimensional pattern, to which horizontal and vertical switches are coupled for selecting the photoelectric conversion elements; horizontal and vertical scanning circuitry for turning the switches "on" and "off" are integrated on the same semiconductor substrate. In order to detect an image with low capacitive lag and high resolution power, the required minimum number (four) of switching elements, adapted to turn respective fields "on" and "off" in a predetermined combination, are connected to an output terminal of each of the unit circuits which constitute the vertical scanning circuit. Using an output scanning pulse from the vertical scanning circuit and a field pulse, interlaced scanning in which two row lines are simultaneously selected in one of the combinations differing for the respective fields is executed so as to derive an optical image through the vertical switches.

摘要： The present invention relates to a color imaging device which suppresses false color signals appearing in an area where the difference of brightnesses is great in the horizontal or vertical direction.When the correlation between picture elements adjacent in the vertical direction is little and the false signal appears in a boundary part in the vertical direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the horizontal direction. On the other hand, when the correlation between picture elements adjacent in the horizontal direction is little and the false signal appears in a boundary part in the horizontal direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the vertical direction.As a result, the moire phenomenon attributed to the false color signals can be conspicuously reduced.While embodiments of the present invention refer to color imaging devices which employ MOS type solid-state imaging devices, the invention is also applicable to an imaging device which employs CCDs and a color image pickup tube which separates colors by means of a mosaic color filter.

摘要： This invention relates to a solid-state imaging apparatus wherein photo signals are read out through MOS type FETs from photosensors such as photodiodes arrayed in two dimensions in large numbers, and consists in remarkably enhancing the signal-to-noise ratio of an output signal by reducing or eliminating noise components to mix into the photo signals.The analysis of the noise components has revealed the correlation in which the noise component in a certain polarity develops in the opposite polarity again after a period that is shorter than one horizontal scanning period by the duration of one horizontal scanning pulse. With note taken of the correlation, a solid-state imaging apparatus comprising a processing circuit which includes a delay circuit and an adder circuit and which cancels the noise is provided.

摘要： An analog signal is stored in an analog memory device, while lower bits of a digital signal obtained by digitizing the analog signal is stored in a digital memory device. An analog signal reproduced from the analog memory device is corrected on the basis of a digital signal reproduced from the digital memory device. The corrected reproduced signal is stored in the memory device again, whereby a recursive storage system is constructed. A signal component degraded by noise in the analog storage is corrected with the digital signal, with the result that storage and reproduction of favorable signal-to-noise ratio are realized.

摘要： Disclosed is a solid-state imaging device wherein optical information of a number of photo-electric conversion elements arranged in a matrix is read into vertical signal lines by a vertical shift register and then the optical information on the vertical signal lines is horizontally scanned by a horizontal register of a charge transfer device. Bias charge storage means and quasi-signal sweep-out drains are disposed between the horizontal register and the vertical signal lines, and a bias charge input means is arranged in the horizontal register. In order to ensure high efficiency in transferring signals between the vertical lines to the storage means, the sweep-out drains and the charge transfer device, it is arranged for bias charges to be provided at each stage of transfer. Thus, bias charges supplied from the storage means are used to transfer charges from the vertical lines to the storage means. Similarly bias charges directly injected from the quasi-signal sweep-out drains are used to sweep out quasi-signals from the storage means to the quasi-signal sweep-out drains. Finally bias charges supplied from the bias charge input means of the charge transfer device are used to read signals from the storage means into the charge transfer device. By virtue of this, the sweep-out efficiency of the quasi-signals from the capacitances which supply the bias charges and a read-out efficiency of the signal charges are enhanced and a high quality of video signal is produced.
