摘要： A color image sensing system includes a CCD image sensor with an optical color filter. A CCD driver is provided to electrically drive the image sensor, which is attached to a vibration table serving as a swing-driver for moving the image sensor along a horizontal direction such that each cell of the image sensor shifts, in a frame period including first and second field periods, between four different sampling positions substantially aligned in the horizontal direction. During each field period, each cell is positioned at two sampling positions, wherein a brightness signal component is produced at one sampling position and color signal components are produced at these sampling positions. The distance between two sampling positions at which the brightness signal components of the first and second field images are produced is set to be half the horizontal pitch of the cells of the image sensor. The remaining two sampling positions of the four sampling positions are apart from each other by one-and-half times the horizontal cell pitch. A color frame image is thus reproduced by electrically adding the first and second field images to increase the number of picture elements to more than the actual number of cells, thereby improving the horizontal image resolution of the frame image and minimizing the generation of color moire in the frame image. The swing-drive operation of the image sensor is repeated in synchronism with the frame period.

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 with two switches which alternately 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： 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 multilayered CCD image sensor having semiconductive cells aligned on a substrate to define picture elements of the image sensor, and a photosensitive layer, which is provided above the substrate, is conducted to the semiconductive cells, and photovoltaicly generates charges of light radiation thereon. A vertical charge transfer section is provided on the substrate and is elongated to be parallel to a linear cell array. A horizontal charge transfer section is coupled to one end portion of the vertical charge transfer section, and a drain layer for sweeping out excess charges is coupled to the other end portion of the vertical charge transfer section. In a normal signal charge readout mode, signal charges from the cells are normally transferred to the horizontal charge transfer section through the vertical charge transfer section. A sweep-out operation of excess charges is performed during a vertical blanking period. In this case, excess charges left in the vertical charge transfer section are transferred through the vertical charge transfer section in a direction opposite to that in the normal signal charge readout mode, and are discharged to the drain layer. No excess charges flow into the horizontal charge transfer section.

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.
