  • Power-supply-noise cancelling circuit and solid-state imaging device
    Patent number: 8531591
    Abstract: A power supply voltage containing a noise component is supplied to each pixel at the time of sampling of a reset level of a signal read out from each pixel, and a power supply voltage in which the noise component is suppressed is supplied to each pixel at the time of sampling of a read level of the signal read out from each pixel.
    Type: Grant
    Filed: March 17, 2010
    Date of Patent: September 10, 2013
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Ryuta Okamoto, Kazumasa Sanada
  • SOLID-STATE IMAGING DEVICE AND METHOD OF EVALUATING BLOOMING
    Publication number: 20120327283
    Abstract: An embodiment includes a pixel array unit in which pixels configured to accumulate charges generated by photoelectric conversion are arranged in matrix, a row scanning circuit that drives the pixels in units of a row, a charge injecting unit that injects charges into the pixels of a portion of the pixel array unit, and a timing control circuit that controls driving timing and charge injection timing of the pixels.
