    • 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.
    • 公开了一种固态成像装置,其中以矩阵形式布置的多个光电转换元件的光学信息被垂直移位寄存器读入垂直信号线,然后垂直信号线上的光信息被水平扫描 电荷转移装置的水平寄存器。 偏置电荷存储装置和准信号扫除漏极设置在水平寄存器和垂直信号线之间,偏置电荷输入装置布置在水平寄存器中。 为了确保在垂直线之间向存储装置,扫除漏极和电荷转移装置传输信号的高效率,布置为在每个转移阶段提供偏置电荷。 因此,使用从存储装置提供的偏置电荷将电荷从垂直线传送到存储装置。 类似地,从准信号扫除漏极直接注入的偏置电荷用于将准信号从存储装置扫除到准信号扫除漏极。 最后,从电荷转移装置的偏置电荷输入装置提供的偏置电荷用于从存储装置读取信号到电荷转移装置中。 由此,来自提供偏置电荷的电容的准信号的扫除效率和信号电荷的读出效率被增强,并且产生高质量的视频信号。

    • A solid state imaging device is disclosed in which photodiodes are arranged regularly in horizontal and vertical directions and generate signal charges in response to incident light, the signal charge thus obtained and smear charges stored on vertical signal lines are alternately and separately transferred to an output end by a horizontal charge transfer device, each of the smear charges is converted at the output end into a first voltage, the resultant charge of a signal charge following the above smear charge and another kind of smear charge is converted at the output end into a second voltage, a reset operation for the smear charge and resultant charge held at the output end is performed at an interval twice as long as the repetition period of a transfer pulse applied to the horizontal charge transfer device, and at least one of the first and second voltages is attenuated or amplified so that a difference between the first and second voltages thus processed provides an image signal in which any smear component is not present and reset noise is greatly reduced.
