  • Method for integrating image sensor
    Patent number: 8279302
    Abstract: Disclosed is a method for integrating an image sensor capable of removing a flicker noise without causing any burdens on a hardware due to setting up additional logics. The method for integrating an exposure time of an image sensor employing a line scan method, including the steps of: performing an integration to a first line when an integer multiple of a light source frequency is different from an integration time; and performing an integration to a second line at a phase substantially equal to a phase in which the integration to the first line is started.
    Type: Grant
    Filed: April 6, 2009
    Date of Patent: October 2, 2012
    Assignee: Intellectual Ventures II LLC
    Inventors: Hyung-Jun Han, Moo-Sup Lim
  • CMOS image sensor and pixel of the same
    Patent number: 7791113
    Abstract: A pixel of an image sensor includes a gate insulation layer formed over a substrate doped with first-type impurities, a transfer gate formed over the gate insulation layer, a photodiode formed in the substrate at one side of the transfer gate, and a floating diffusion node formed in the substrate at the other side of the transfer gate, wherein the transfer gate has a negative bias during a charge integration cycle.
