Abstract
A method, of interpolating missing colors in a color filter array comprising red, green and blue photosites comprises determining and interpolation direction for each red and each blue photosite based on local edge information and interpolating a green color for each red and each blue photosite in the determined interpolation direction for that photosite. For each green photosite, red and blue colors are interpolated. For each red photosite, a blue color is interpolated in the determined interpolation direction for that photosite and for each blue photosite, a red color is interpolated in the determined interpolation direction for that photosite.
