摘要： The solid state image sensor has a photosensing region formed on a substrate. The photosensing region has a plurality of photocells for receiving an incident image. The photosensing region is capable of changing image sampling modes by relatively shifting image sampling points for the incident image. In the photosensing region, a plurality of first transfer elements are formed and the first transfer elements receive the signal charges from adjoining photocells and transfer them out. Further, a temporary storage region is formed on the substrate having a plurality of second transfer elements therein for each of the first transfer elements. Each of the second transfer elements has a capacity to accommodate all of the signal charges of a corresponding first transfer elements which are read out from the photocells at the same time. A plurality of gate elements are respectively formed between each of the first transfer elements and their corresponding plurality of second transfer elements. Each gate elements changes transfer direction from one of the first transfer elements between at least two of the second transfer elements based on the sampling mode for the incident image. Third transfer elements are formed adjacent to the temporary storage region. The third transfer elements repeat a readout cycle of receiving the signal charges from a plurality of second transfer elements and then transferring them out.

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.

摘要： In an image sensing system, a solid-state image sensor is mounted on a vibration stand in a manner as to vibrate horizontally to an incoming light in synchronization with one frame period, thereby sensing while alternatively displacing at different sampling positions in two field periods. Field image signals from the image sensor is supplied, through a signal processor, to a signal reproduction unit which includes a carrier generator for producing first and second carrier signals having the same frequency as the horizontal readout frequency of the image sensor and a phase in reverse to one other in the field periods, and an AM modulator for amplitude-modulating the carrier signal. The amplitude modulation field signals thus obtained are sliced at a suitable level by a slicer and then synthesized each other to obtain a frame image signal.

摘要： A solid state image-sensing device which comprises an image-sensing area formed of a plurality of matrix-arranged cells exposed to an introduced image light and an optical black connected to a readout section in parallel relationship with the image-sensing area. An image light is prevented from entering the optical black. Only noise charges (dark current charges) sent forth from the optical black are transferred to a control circuit. A gate electrode control signal for eliminating charges whose amount corresponds to that of the noise charges from the total charges collected in the storage regions of the matrix-arranged cells of the image-sensing area is produced by a control circuit. The gate electrode control signal is supplied to a gate electrode positioned between the photosensing section and vertical transfer section of the cells of the image-sensing area. A potential well lying under the gate electrode has its depth controlled by the gate electrode control signal. At first, a charge whose amount is substantially equal to that of a light-generated signal charge stored in the storage region of the image-sensing area is transferred to a vertical transfer section. After elimination of the noise charges, the remaining charges are returned at least once to the photosensing sections of the respective cells to be held in the storage regions of the photosensing sections of the cells for a prescribed length of time.
