Abstract
A video coding method includes the following steps: performing a first optimization operation on a sub-coding block to select original pixels or reconstructed pixels of an adjacent block of the sub-coding block according to a base prediction mode to generate an intermediate prediction mode of the sub-coding block; performing a second optimization operation on the sub-coding block to determine a prediction mode according to the intermediate prediction mode, the original pixels of the sub-coding block, and the reconstructed pixels of the adjacent block; generating prediction information of the sub-coding block according to the original pixels of the sub-coding block, the reconstructed pixels of the adjacent block, and the prediction mode; generating encoding coefficients and reconstructed pixels of the sub-coding block according to the prediction information of the sub-coding block; and generating a bit stream according to the encoding coefficients and the prediction information.
