COLOR FILTERS AND DEMOSAICING TECHNIQUES FOR DIGITAL IMAGING
Color filter arrays or mosaics are provided for imaging a scene with diffraction limited optics. A distribution of color types in a color filter array is biased toward smaller wavelengths to avoid or reduce loss of spatial resolution information at higher wavelengths due to a larger extent of diffraction at the higher wavelengths. Demosaicing methods for reconstructing a partial or full color image from raw image data involve applying correction factors to account for diffraction. The correction factors are based on pixel size and/or a measure of the extent of diffraction (e.g., an Air disk diameter for each wavelength in the color filter array.
