    摘要: In a solid state imaging device in which two signals on two horizontal scanning lines are read out simultaneously for easy image enhancement, the two signals read from the two horizontal scanning lines are subtracted from each other while they are added together, and the difference signal is added to the sum signal so as to produce a video signal subject to the image enhancement. As a solid state image sensor, a MOS type image sensor as well as a CCD, CID or CC type image sensor may be used.

    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: A camera tube device for use in, for example, a television camera comprises a cathode emitting electrons, and a first grid and a second grid having respective apertures for converging the electrons emitted from the cathode into a fine electron beam. The aperture of the second grid is sufficiently smaller than that of the first grid and plays an important role for the formation of the electron beam. The electron beam scans a target carrying a charge pattern corresponding to the luminous intensity of an object. Voltages applied to the first and second grids are controlled so as to provide the electron beam quantity corresponding to the luminous intensity of the object forming the charge pattern of the target.

    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.
