摘要： A solid-state imaging device is constructed by integrating a plurality of face plate elements of an imager in the shape of a matrix on a semiconductor substrate. The face plate elements are formed of photodiodes, in which charges corresponding to incident light are accumulated. The charges are converted into currents or voltages by a plurality of amplifying means disposed in the matrix and which are provided adjacent to the photodiodes. The currents or the voltages obtained through conversion are delivered out of the matrix through signal lines. To the signal lines a correlated double sampling circuit is connected, and this curcuit detects a difference in outputs of the amplifying means between a case when the charges of the photodiodes are not present in the input portions of the amplifying means and a case when they are present therein.

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： 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.
