    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: 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.
