Improved intra-color signal prediction and inter-color signal prediction for Bayer image coding

摘要

An apparatus and method for selecting use of inter prediction or intra prediction during enhanced Bayer image encoding and decoding is provided. In-plane prediction relies on the correlation between adjacent pixels of the same color, and inter-plane prediction relies on the correlation between adjacent pixels in different color planes (ie, different colors). To eliminate large residuals that may occur in certain large edge situations, a dynamic range decision is made that selects whether to use in-plane prediction or inter-plane prediction.
