  • Correlated double sampling to include a controller to increment and invert a count during a first period and a second period
    Patent number: 8969770
    Abstract: Apparatus and a method for correlated double sampling using an up-counter for parallel image sensors. All bits of a counter are set to one. An offset signal is compared to a first reference signal to define a first period during which the counter is incremented. After the first period, all bits of the counter are inverted. A sensor signal is compared to a second reference signal to define a second period during which the counter is incremented to generate a correlated double sampling value.
    Type: Grant

  • Method and apparatus for shielding correction pixels from spurious charges in an imager
    Patent number: 7830412
    Abstract: A barrier for isolating the dark correction pixels from spurious charges within an image sensor. The barrier comprises a charge absorbing region in a substrate electrically connected to a voltage source terminal. The charge absorbing region completely surrounds the dark correction region of a pixel array. The charge absorbing region absorbs carriers generated by lateral diffusion, near-infrared and infrared light reflected from the bottom of the silicon substrate, and other sources. This absorbing region prevents carriers from being absorbed into the dark correction pixel cells and causing image correction distorting effects.
