    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： 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： This invention relates to an area imaging device having an array of picture elements formed of photodiodes and insulated-gate MOSTs which is vertically scanned by a shift register and horizontally scanned by a charge transfer device (CTD). The solid-state imaging device according to this invention has a transfer MOST provided between a vertical signal output line and a horizontal switch MOST, a resetting MOST connected to the junction between said transfer MOST and the horizontal switch MOST, and a mechanism for setting the vertical signal line at a reference potential just before signal transfer. The transfer MOST connected between the junction of the horizontal switch MOST and the resetting MOST and the vertical signal line is a double-gate MOST formed of a series connection of a transfer gate and another transfer gate. Therefore, the charges under the gate of the transfer MOST can be removed for fixed noise to be greatly reduced.

    摘要： A high resolution solid-state color imaging apparatus having two-dimensionally disposed photoelectric sensors are arranged in rows and columns each having a color spectral responsivity characteristic such as by employing color filters. Each of the photoelectric sensors is scanned so as to obtain an intensity signal with respect to each row of each field, and wherein scanning of each field is for the same number of rows as that of each frame. Intensity signals are obtained only by the scanned output of each row. Additional intensity signals equal to half the number of said first mentioned intensity signals are obtained by a 2:1 subsampling of bandwidth-restricted signals by a filter along the vertical temporal frequency, thereby realizing high vertical resolution by the photoelectric image sensors of conventional row numbers and having compatibility with a conventional NTSC system and, furthermore, eliminating aliasing distortion.
