A system and method for effectively performing an intra prediction procedure with an electronic device includes an encoder that utilizes a delta value comparison procedure to identify optimal delta values for creating optimal predicted blocks of image data corresponding to original blocks of image data. The encoder then utilizes the original blocks and the optimal predicted blocks to generate residual blocks that represent the original blocks in an encoded format. The encoder then generates a bitstream containing the delta value information and the residual block for storage or transmission purposes. A decoder may decode the delta values and the residual block to reconstruct the image block.
