  • Patent number: 7944495
    Abstract: In a case where a thinning operation is implemented at the point when signal charges are read out from each of pixels to thin out pixel information by lines (row), the thinning may be performed only in the vertical direction, but not in the horizontal direction. In an all-pixel-read-out type CCD image pickup element, a discharge controlling section is provided in each of VH transfer stage sections transferring signal charges from vertical CCDs to a horizontal CCD, and where a thinning mode is selected, among those signal charges transferred from a plurality of the vertical CCDs, those of a given set of columns are stopped and discharged at the respective discharge controlling sections, and those of the rest of columns are transferred to the horizontal CCD, and at the same time, those of a given set of lines (rows) are stopped and discharged for all columns, thereby performing the thinning operation over the pixel information in both the vertical and horizontal directions at the VH transfer stage.

  • Patent number: 5990952
    Abstract: A method driving for a solid-state image pickup device in which it is possible to achieve a high dynamic range readout without causing unnaturalness in the reproduced picture particularly even when filming a subject moving at high speed. Primary signal charges are generated by adjacent first and second pixels and are subsequently mixed in the vertical transfer register. Auxiliary signal charges are also generated in adjacent first and second pixels, and, generation of the primary signal charge for the second pixel occurs prior to generation of the auxiliary signal charge of the first pixel.

  • Patent number: 5821750
    Abstract: A plurality (e.g., an odd number) of CCD shift registers are provided in parallel, and a channel stop separates between the respective adjacent CCD shift registers and is partially cut out in order to make it possible for a carrier which passes through the CCD shift registers to move toward the side portion. Carrier (electrons) supplied from an input section to the center CCD shift register are measured at the outputs of the other CCD shift registers, and the intensity (the magnetic-flux density) of the magnetic field is determined on the basis of the absolute value thereof, and the direction of the lines of magnetic force is determined on the basis of whether the difference is positive or negative.

  • Patent number: 5793423
    Abstract: The present invention is directed to a solid state image sensing device of an amplifying type which can increase a switching speed during the horizontal scanning by making an output circuit low in impedance. In the output circuit of this amplifying type solid state image sensing device, the FET of source-follower configuration functions as a buffer and a horizontal gate switch. A first switching means is coupled between an output terminal of a capacitor connected to each vertical signal line and the gate electrode of the FET and a second switching means is coupled between the gate electrode of the FET and a reference potential point, respectively, whereby an output resistance and a load capacitance of the output circuit are reduced to enable the output circuit to become low in output impedance.

  • Patent number: 5420631
    Abstract: A solid state imaging device includes an image sensor having a two-dimensional matrix of picture elements. A first vertical scanning circuit provides a first vertical scanning signal, while a second vertical scanning circuit provides second and third vertical scanning signals. A switching circuit is coupled with horizonal lines of picture elements in the image sensor on one vertical side of the two-dimensional matrix and serves to switch either the first vertical scanning signal from the first vertical scanning circuit to the horizontal lines of picture elements, or in the alternative, the second and third vertical scanning signals from the second vertical scanning circuit thereto. When selected by the switching circuit, the first vertical scanning signal reads the picture elements in a respective horizontal line and a horizontal scanning circuit scans the picture elements in the selected horizontal line to read image signals from these picture elements.

  • Patent number: 5379068
    Abstract: Solid state imaging devices include an image sensor having a two-dimensional matrix of picture elements arranged horizontally and vertically. A vertical scanning circuit selects horizontal lines of picture elements within the two-dimensional matrix in a predetermined order for reading the picture elements. A horizontal scanning circuit coupled with a plurality of vertical lines joining vertically spaced ones of the picture elements serves to select picture elements in the horizontal lines selected by the vertical scanning circuit to output image signals therefrom. The horizontal scanning circuit is operative to scan the picture elements of the selected horizontal lines through one side of the two-dimensional matrix in a first horizontal direction to output a normal image signal.
