  • Patent number: 7573519
    Abstract: A CMOS image sensor includes a plurality of pixels arranged column and rows in an array; a column circuit for storing reset values and a value after integration; a correlated double sampler which derives an image signal from the reset and the value after integration; and an anti-eclipse circuit physically separately from the column circuit and electrically connected to one or shared between multiple columns of pixels for restoring corrupted column voltage on a column of pixels.

  • Patent number: 7391001
    Abstract: An image sensor includes a substrate having photosensitive areas; an insulator spanning the substrate; and a first and second layer of a multi-layer metallization structure, wherein the first layer forms light shield regions over selected portions of the photosensitive area as well forming circuit interconnections and barrier regions to prevent spiking into the substrate or gates at contacts in the non-imaging area; and the second layer spanning the interconnections and barrier regions of the first layer only over the non-imaging areas and the second layer overlays edges of the first layer.

  • Patent number: 7385638
    Abstract: A method for reading out charge from an interlined CCD having a plurality of photo-sensing regions and a plurality of vertical shift registers, and each photosensitive region is mated respectively to a CCD of a vertical shift register and a color filter having a repeating pattern of two rows in which each row includes at least two colors spanning the photo-sensing regions, the method includes reading out one row from each of the two row pattern; summing the same color from each row in the vertical shift register to reduce the resolution by one half; without transferring charge out of the vertical shift register, repeating the reading and summing steps for the remaining row; and reading out the charge in the vertical shift registers in a manner in which different colors are not summed together.

  • Patent number: 7385636
    Abstract: An image sensor includes a plurality of pixels for capturing incident light that is converted to a signal representing an image; wherein noise is combined with a signal representing both the image and a reset level; a plurality of dark reference pixels that generate noise that substantially correspond or equally correspond to the noise in the image and reset level; and a sample and hold circuit that reads out the image signal and cancels or substantially cancels out the noise from the image signal and reset level by canceling the noise from image and reset level with the noise generated from the dark reference pixels.

  • Patent number: 7379107
    Abstract: A method for reading out charge from an interlined CCD having a plurality of photo-sensing regions and a plurality of vertical shift registers, and each photosensitive region is mated respectively to a CCD of a vertical shift register and a color filter having a repeating pattern of two rows in which each row includes at least two colors that forms a plurality of 5 line sub-arrays sequentially numbered in the space domain; and the color filter spanning the photo-sensing regions, the method includes sequentially or substantially simultaneously reading out lines 1, 3 and 5 into the vertical shift register that keeps the colors separated; summing the charge in lines 1, 3 and 5; sequentially or substantially simultaneously reading out lines 2 and 4 into the vertical shift register that keeps the colors separated; summing the charge in lines 2 and 4; transferring one or more rows of the summed charge into a first horizontal charge-coupled device; transferring alternate charges in the first horizontal charge-couple
