The present invention is directed to a method and apparatus for improving the efficiency of color correcting subsampled color image data. More specifically, the present invention is directed to taking advantage of a method of applying a full conversion between color spaces on a master set of pixels in an image. New values are assigned to the remaining pixel subset by interpolating from the converted master set of pixels. The interpolation error is then added to the pixel subset, and the master set and subset are merged to produce a full converted color image set, which is subjected to further processing as a single unit.
