1. A method of producing a full color digital image from a mosaic digital image having sampled values, the method comprising:
- estimating a full color output image from the mosaic image;
transforming the output image from an original color space into a luminance/chrominance color space;
smoothing chrominance components of the transformed image;
re-transforming the image with the smoothed chrominance components back to the original color space; and
re-setting corresponding pixels in the re-transformed image to the sampled values.

Abstract
A full color output image is estimated from a mosaic digital image, the output image is transformed from an original color space into a luminance/chrominance color space, chrominance components of the transformed output image are smoothed, the image is re-transformed back to its original color space, and corresponding pixels in the re-transformed image are re-set to sampled values.
