  • Publication number: 20110310279
    Abstract: A method for using a capture device to capture at least two video signals corresponding to a scene, includes: providing a two-dimensional image sensor having a plurality of pixels; reading a first group of pixels from the image sensor at a first frame rate to produce a first video signal of the image scene; reading a second group of pixels from the image sensor at a second frame rate for producing a second video signal; and using at least one of the video signals for adjusting one or more of the capture device parameters.

  • Publication number: 20110211109
    Abstract: A system for capturing a color image, includes a two-dimensional array having first and second groups of pixels, pixels from the first group of pixels have narrower spectral photoresponses than pixels from the second group of pixels and the first group of pixels has individual pixels that have spectral photoresponses that correspond to a set of at least two colors; the placement of the first and second groups of pixels defining a pattern that has a minimal repeating unit including at least twelve pixels, and a plurality of non-overlapping cells wherein each cell has at least two pixels representing a specific color selected from the first group of pixels and a plurality of pixels selected from the second group of pixels; a structure for combining pixels of like color from at least two of the plurality of cells within the minimal repeating unit.

  • Patent number: 7999870
    Abstract: A CMOS image sensor or other type of image sensor comprises an array of pixels arranged in rows and columns, with the columns being separated into groups each comprising two or more columns that share a common output. The image sensor further comprises sampling and readout circuitry that includes, for each group of columns in the pixel array, a corresponding set of two or more column circuits. The sampling and readout circuitry is configured to sample the common output for each group of columns independently into one of the column circuits associated with that group, and to read out the common output for each group of columns as previously sampled into another of the column circuits associated with that group. The image sensor may be implemented in a digital camera or other type of image capture device.

  • Publication number: 20110157444
    Abstract: An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. An analog front end (AFE) circuit processes pixel data output from the output circuits and an AFE clock controller transmits an AFE clocking signal to the AFE circuit to effect processing of the pixel data. A timing generator outputs a column address sequence that is received by a column decoder. During one or more sample operations the AFE clock controller suspends the output of the AFE clocking signal and the timing generator suspends the output of the column address sequence during the sample operation. The output of the AFE clocking signal and the column address sequence resume at the end of the sample operation.

  • Publication number: 20110157395
    Abstract: A system-on-chip (SOC) includes an image sensor, an image signal processor connected to an output of the image sensor, a bypass connected to the output of the image sensor, and a multiplexer connected to an output of the image signal processor and an output of the bypass. The image sensor, image signal processor, bypass, and multiplexer are all integrated on one silicon wafer. An image capture device includes the SOC and applications processor connected to an output of the multiplexer. The image capture device can further include a system memory and a display connected to the applications processor.

  • Publication number: 20110157433
    Abstract: An image sensor includes multiple photoactive pixels and multiple dark reference pixels typically arranged in rows and columns to form a pixel array. A dark signal is read out from a given number of dark reference pixels in each column at a first gain level. An initial column offset correction is determined for one or more columns in the pixel array using respective dark signals read out at the first gain level. The initial column offset corrections are repeatedly scaled in response to each detected change to a different gain level. The column offset corrections can be scaled based on an amount of change between each respective different gain level and the first gain level.

  • Publication number: 20110147875
    Abstract: An image sensor includes a pixel array having photoactive pixels and dark reference pixels. The photoactive pixels can be configured in a sub-array within the pixel array. Well contacts are only placed along opposing sides or edges of the sub-array of photoactive pixels or along opposing sides or edges of the pixel array.

  • Publication number: 20110075007
    Abstract: Multiple images are captured where the exposure times for some of the images overlap and the images are spatially overlapped. Charge packets are transferred from one or more portions of pixels after particular integration periods, thereby enabling the portion or portions of pixels to begin another integration period while one or more other portions of pixels continue to integrate charge. Charge packets may be binned during readout of the images from the image sensor. Comparison of two or more images having different lengths of overlapping or non-overlapping exposure periods provides motion information. The multiple images can then be aligned to compensate for motion between the images and assembled into a combined image with an improved signal to noise ratio and reduced motion blur.
