Efficient image demosaicing and local contrast enhancement

摘要

An exemplary demosaicing method includes a demosaic module receiving a frame of raw pixels, generating vertical and horizontal estimated color pixel values for missing color pixel values using information from the frame of raw pixels, generating vertical and horizontal color difference signals using information from the frame of raw pixels and the vertical and horizontal estimated color pixel values, and creating a full resolution frame of pixels using information from the frame of raw pixels and color difference signals selected from the vertical and horizontal color difference signals. The full resolution frame of pixels may include one captured color pixel value and two reconstructed color pixel values for each location in the full resolution frame of pixels and may be sent to a display unit for display.
