    摘要: A charge-transfer device contains a high-resistance p-well layer formed in the surface of an n-type semiconductor substrate. In the surface of the well layer, a charge-transfer n-channel layer, a charge storage n-channel layer, a charge release n-channel layer, and a charge release n-type drain are formed continuously. An output gate electrode is provided above the junction of the transfer channel layer and the storage channel layer, with an insulating film interposed therebetween. Provided above the release channel layer is a reset gate electrode with an insulating film interposed therebetween. In the surface of the storage channel layer, a charge-sensing p-channel layer of a charge-sensing transistor is formed. The charge-sensing channel layer is arranged so as to be in contact with neither the transfer channel layer nor the release channel layer. The storage channel layer is arranged so as to contain a first surface portion which adjoins the transfer channel layer and is in contact with a covering insulating film, and a second surface portion which adjoins the release channel layer and is in contact with the covering insulating film. In the surface of the substrate, a p-type source and drain layers of the charge-sensing transistor are formed so as to face each other with the sensing channel interposed therebetween. The potential of the storage channel layer without charges is set higher than that of the release drain layer.

    摘要: In a real-time video signal processor for processing an input digital video signal divisible into a succession of principal blocks each of which has at least one scanning line and a time duration shorter than a frame period, each principal block is divided into at least two partial blocks with each scanning line divided into the respective partial blocks. A plurality of signal processing modules are assigned with the respective partial blocks of each principal block, respectively. Responsive to the input digital video signal and an additional digital video signal, the signal processing modules process the respective partial blocks of each principal block into processed signals during the time duration, respectively. Each processed signal comprises a first partial signal used as an output signal of the processor and a second partial signal. A delaying circuit delays the second partial signals derived from the signal processing modules into a delayed signal having a delay equal to a difference between the frame period and the time duration. The delayed signal is used as the additional signal. A plurality of the real-time video signal processors may be connected in cascade to each other. Two memory units may be used instead of the delaying circuit. Readout operation of each principal block from the memory units is controlled by control signals produced by a control signal producing circuit. Principal blocks read out of the memory units are supplied to the signal processing modules.

    摘要: A solid-state image sensor has an electrically floating carrier detecting electrode formed on a substrate, into which the signal carriers are transmitted, a sense amplifier circuit detecting the variation in a voltage of the electrode at the time of transferring the carriers, and a resetting electrode for resetting the potential of the electrode to a predetermined potential at every read-out period of the picture element section. A circuit arrangement for removing noise is provided to have two switches which switch to alternatively become conductive in response to control pulse signals. The first switch becomes conductive during a first period within one picture element period. During the first period the CCD output signal contains an effective image signal component. The second switch becomes conductive during a second period during which the CCD output signal contains a reset noise component, thereby forcibly fixing the level of the reset noise signal to a DC reference potential so that reset noise can be removed.
