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.
