    摘要: A solid-state image sensing device, such as an interline-transfer type charge-coupled device (IT-CCD), produces signal carriers in response to incident light and generates an image pickup signal. One frame of the image signal is formed of two fields. The CCD chip is coupled to fixed bimorph piezoelectric vibrators by which it is given a wobbling-swing drive during image pickup. This wobbling-swing drive is controlled by a vibration controller. This vibration controller controls the vibration mode of the bimorph piezoelectric elements to apply a first vibration (swing vibration) to the CCD such that each pixel cell is displaced to a different sampling position in the plurality of field periods included in one frame period for image pickup, and applying a second vibration, i.e., a swing vibration with wobbling superposed, to the CCD such that each pixel cell is wobbled while picking up an image in each sampling position, which is positioned in each field period.

    摘要: A solid-state imaging device is disclosed, which includes a CCD image sensor having a detection section formed on a substrate at its output stage. The detection section receives a signal charge transferred from a photosensitive cell section, and generates an image voltage signal corresponding to the signal charge. The detection section has an electrically floating semiconductor diffusion layer formed in the substrate. A packet of signal charges from each picture element cell is temporarily stored in the diffusion layer. A reset section is provided to the output stage of the image sensor. The reset section has a reset drain layer so formed in the substrate as to be located near the diffusion layer and a reset gate for controlling flow of charges between the diffusion layer and the reset drain layer. The reset control unit is connected to the reset gate. The reset control unit applies a normal reset pulse signal to the reset gate in a vertical effective period of the image sensor. In a vertical blanking period of the image sensor, the reset control unit applies a reset pulse signal having a phase opposite to that of the normal reset pulse signal to the reset gate.

    摘要: A multilayered solid-state image sensor has a photoconductive film, which covers pixels formed on a substrate, and acts as a photoelectric converting section for the pixels. The photoconductive film inherently has traps. In an imaging mode of the image sensor, before signal charges are generated in a portion of the photoconductive film corresponding to each pixel upon irradiation of image light, sufficient bias charges to fill all the traps in the photoconductive film are injected into the photoconductive film. Subsequently, excess bias charges remaining in the photoconductive film are removed therefrom. Thus, the traps in the photoconductive film are effectively filled with the bias charges, thereby deactivating the photoconductive film.

    摘要: In a CMOS image sensor, current leakage after a series of noise removing operations has been completed is suppressed in a read operation for each horizontal line, thereby suppressing image noise occurring on the output display screen of the image sensor. There are provided signal storage regions for storing the signals read from the unit cells in the same row selected in the imaging area onto vertical signal lines and horizontal select transistors for sequentially selecting and reading the signals stored in the individual signal storage regions and transferring them to read horizontal signal lines. At least in the period during which the signals are read from the signal storage regions, one of the drain and source of the transistor electrically connected to the signal path between the vertical signal line and horizontal signal line is biased in the reverse direction with respect to the substrate region. Two adjacent ones of the horizontal select transistors form a pair. The horizontal select transistors in each pair share one of the source/drain regions so as to be connected to the horizontal signal line in common, and the others of the source/drain regions are connected to the vertical signal line individually.

    摘要: An image pickup apparatus comprising an array of unit cells, vertical signal lines, and a control circuit. The unit cells are arranged in rows and columns. Each unit cell has a light-receiving device for receiving light and generating an electric charge corresponding to the light, a charge-accumulating section for accumulating the electric charge generated by the light-receiving device, a transfer device for transferring the electric charge from the light-receiving device to the charge-accumulating section, and a charge-limiting device for limiting the electric charge accumulated in the charge-accumulating section. The vertical signal lines extend along the columns of unit cells, respectively, each for receiving a electric data item corresponding to the electric charge accumulated in the charge-accumulating section of any unit cell of the associated column. The control circuit controls each of the unit cells, causing the charge-limiting device to limit the charge generated by the light-receiving device during a first period and transferred to the charge-accumulating section through the transfer device. The charge generated by the light-receiving device during a second period following the first period and transferred to the charge-accumulating section through the transfer device is added to the electric charge accumulated in the charge-accumulating section.

    摘要: In a solid state image sensor device comprising a cell area wherein unit cells each having photoelectric diodes are arranged in a matrix form on a semiconductor substrate, the cell area being composed of a photo-sensitive pixel region for sensing an image, and an optical black pixel region for defining an optical black level, and a vertical shift register for selecting the unit cells of the image sensing cell array, in a group along each of horizontal lines, and vertical signal lines, each of which reads each of signals from the unit cells selected by turning on an address register by means of the vertical shift register, the vertical signal lines in the optical black pixel region are connected with each other through a wiring. Since the vertical signal lines in the optical black pixel region are connected with each other by a wiring, even if outputs from an optical black pixel region vary in the pixels, the outputs are made averaged and uniform and a variation in fixed pattern noises between the horizontal lines are reduced.
