  • Scaling Algorithm And Architecture For Integer Scaling In Video

    view source
  • US Patent:
    6348929, Feb 19, 2002
  • Filed:
    Jan 16, 1998
  • Appl. No.:
    09/008131
  • Inventors:
    Tinku Acharya - Tempe AZ
    Werner Metz - Chandler AZ
  • Assignee:
    Intel Corporation - Santa Clara CA
  • International Classification:
    H04N 314
  • US Classification:
    345660, 345666, 345667, 345668, 345669, 348273
  • Abstract:
    A method for scaling of an image that includes providing an N-tap filter to be applied upon an image region and applying the N-tap filter variously to the image region and obtaining therefrom at least one scaled image pixel, such that N is equal to the scaling factor plus one. For instance, a 4:1 scaling procedure is achieved using a five-tap filter. By carefully selecting the coefficient of the five-tap filter, 2:1 scaling with a three-tap filter may be achieved using the same hardware and adding control signals and selectors. The scaling methodology and apparatus work directly in the CFA domain and provide efficient single pass dual-moded or multi-moded scaling capability.
  • Efficient Companding Algorithm Suitable For Color Imaging

  • US Patent:
    6351555, Feb 26, 2002
  • Filed:
    Jan 13, 2000
  • Appl. No.:
    09/482551
  • Inventors:
    Tinku Acharya - Tempe AZ
    Werner Metz - Chandler AZ
  • Assignee:
    Intel Corporation - Santa Clara CA
  • International Classification:
    G06K 900
  • US Classification:
    382162, 382166, 382274
  • Abstract:
    A companding method is disclosed where a set of factors related to the color characteristics of captured images are determined. Using these characteristics, a companding scheme is developed such that each pixel is lowered in resolution, but in such a manner that the image retains important features. These factors related to color characteristics are determined in part by analyzing histograms related to the image.
  • Median Computation-Based Integrated Color Interpolation And Color Space Conversion Methodology From 8-Bit Bayer Pattern Rgb Color Space To 12-Bit Ycrcb Color Space

  • US Patent:
    6356276, Mar 12, 2002
  • Filed:
    Mar 18, 1998
  • Appl. No.:
    09/040806
  • Inventors:
    Tinku Acharya - Tempe AZ
  • Assignee:
    Intel Corporation - Santa Clara CA
  • International Classification:
    G09G 504
  • US Classification:
    345600, 345589, 345427, 345604
  • Abstract:
    An integrated color interpolation and color space conversion technique and apparatus. A raw image that is arranged in a Bayer pattern where each pixel has only one of the color components needed to form a full color resolution pixel may be converted using this technique directly to a YCrCb image space without any intermediate conversion or interpolation steps. Specifically, in one instance, an 8-bit Bayer pattern raw image may be converted directly to a 12-bit YCrCb space in a single step approach. Such an integrated technique may more readily and inexpensively implemented in hardware such as on a digital camera, or in software.

  • US Patent:
    6381357, Apr 30, 2002
  • Filed:
    Feb 26, 1999
  • Appl. No.:
    09/258636
  • Inventors:
    Tinku Acharya - Tempe AZ
  • Assignee:

    G06K 900
  • US Classification:
    382141, 348246
  • Abstract:
    What is disclosed is a method including downloading a sequence of images from an image sensor, and then marking on a map a pixel location of the sensor defective if a Defective Vote score exceeds a first threshold, the score tallied over all captured images.
