Abstract:
A method of generating missing color values for pixels in an array, each pixel having one of at least first, second, and third color values, comprising:determining values for all missing second color values for pixels in the array through interpolation of known second color values adjacent along diagonal lines from the missing second color values by determining temporary values for the second color which lie at the corners of pixels having known second color values using filters oriented along diagonally adjacent second color pixels and by determining final values for the second color at centers of pixels having known first and third color values by using filters oriented along diagonally adjacent first and third color pixels and sampling the temporary second color values; anddetermining values for all missing first and third color values for the pixels from a sum of an interpolation term and a luminance correction term based on differences between second color values of adjacent pixels.
