  • Patent number: 8218048
    Abstract: By providing dummy pixels separately from effective pixels, the total number of pixel rows is equalized with the number of horizontal sync signals included in one frame interval (which is called an “HD number”). A period during which a reset signal for an electronic shuttering operation is being supplied to an arbitrary pixel row overlaps with a period during which another pixel row is selected to perform a readout operation thereon. Thus, it is possible to suppress a variation in reset potential among effective pixels.

  • Patent number: 8149308
    Abstract: A high dynamic range solid-state image pickup device is provided with a plurality of unit cells, which convert light into signal charges and accumulate the signal charges. The unit cells are arranged by rows and columns for outputting a signal voltage corresponding to the signal charges. A selector and a read transistor set an accumulation time period for accumulating the signal charges in the unit cells to a first period and a second period different from each other. The row selector and a vertical selection transistor select a row. Sampling capacitors (210a, 210b) are connected to the unit cell of each column. A pulse generator and sampling transistors select an arbitrary sampling capacitor from the sampling capacitors. The pulse generator and the sampling transistors perform selection so as to accumulate the signal voltage corresponding to the signal charges accumulated during the first period and the second period in the sampling capacitors, respectively.
