METHOD AND APPARATUS FOR DETERMINING ENCODING MODE BASED ON TEMPORAL AND SPATIAL COMPLEXITY

摘要

The present invention relates to a method and an apparatus for determining an encoding mode based on temporal and spatial complexity. The encoding-mode-determining apparatus based on temporal complexity is characterized in that it comprises: a temporal complexity calculation unit which calculates the temporal complexity of a macro block; and a mode determining unit which determines the encoding mode based on temporal complexity. The temporal complexity and the spatial complexity of a macroblock can be calculated with higher accuracy, and additionally the optimal encoding mode can be selected based on the calculated complexity. Accordingly, the complexity of the calculation involved in rate-distortion optimization can be reduced and the processing speed can be increased.
