Inventors: Acharya, Tinku;
Assignee: Intel Corporation (Santa Clara, CA)
Primary Examiner: Lee; Thomas D.
Assistant Examiner: Chen; Wenpeng
Attorney, Agent or Firm: Blakely, Sokoloff, Taylor & Zafman LLP

What is disclosed is method that interpolates missing color components for an original pixel by utilizing color medians for surrounding blocks of green pixels. A new pixel is output which has complete color information which is a function of the original pixel and interpolated color components. The interpolated pixel is a true representation of both luminance and chrominance information.

DETAILED DESCRIPTION An interpolation method is disclosed for a raw image composed of pixels that utilizes color medians of surrounding blocks of Green pixels in order to select neighboring pixels to attain missing color components for a raw image pixel.
A new pixel is formed that has full color information which is a function of the raw image pixel and the interpolated color components.
