    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.

    摘要: Herein disclosed is a method of reducing the vertical smears which are generated in a solid state image sensor including a plurality of vertical signal lines for transferring signal charges in a vertical direction and at least one charge transfer device for transferring the signal charges in a horizontal direction.The smear charges stored in the vertical signal lines and the signal charges generated in a photoelectric conversion element in response to an incident ray are inputted separately of each other for a horizontal blanking period to the charge transfer device for the horizontal transfer. During a tracing period, a smear voltage and a signal voltage are outputted separately of each other from said charge transfer device. The smear voltage adjusted is subtracted from the signal voltage to eliminate the smear component which has been mixed into the signal voltage.

    摘要: A solid stage imaging device, in which photodiodes each capable of converting incident light into a electric charge and accumulating the electric charge are arranged regularly in a matrix, e.g. in horizontal and vertical directions, and electric charges of the photodiodes are sent to the outside by means of CCD's, includes a scanning circuit which scans switching MOS transistors for transferring the electric charges of the photodiodes to vertical CCD's, in a vertical direction so that switching MOS transistors in a row parallel to a horizontal direction can be driven independently of switching MOS transistors in another row. When the solid state imaging device is driven, an operation for transferring an electric charge in each vertical CCD and an operation for driving switching MOS transistors in the next row with the aid of the scanning circuit are alternately performed, to reduce the amount of smear and to increase the dynamic range of each vertical CCD, without increasing the number of CCD's used.
