Method of determining missing color values for pixels in a color filter array |
摘要 |
Missing color values for pixels in a color filter array created by a digital camera and having a Bayer pattern are generated by determining values for all missing green color values for pixels in the color filter array by interpolation of known green color values adjacent along diagonal lines and determining values for all missing red and blue color values for the pixels from the sum of an interpolation term and a luminance correction term based on differences between green color values of adjacent pixels. The missing green color values are determined by computing temporary values for green which lie at the corners of pixels having known green color values using cubic B-spline filters oriented along diagonally adjacent green color pixels, determining final values for green at the centers of pixels having known red and blue values by using cubic B-spline filters oriented along diagonally adjacent red and blue color pixels, and by sampling the temporary green values.
