Interactions between color plane interpolation and other image processing functions in electronic photography
James E. Adams · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1995
Electronic cameras using a single CCD detector acquire scene color by subsampling in three, color planes and subsequently interpolating the information to reconstruct three, full-resolution color planes. The nature and size of the interpolation errors are a function of the algorithm used. When interpolation errors are propagated through the rest of the imaging chain, it becomes evident that synergistic effects among image processing operations must be considered when selecting and tuning an interpolation algorithm. This presentation demonstrates and comments on these image processing interactions.
