METHOD AND APPARATUS FOR DETERMINING INTRA PREDICTION MODE OF IMAGE CODING UNIT, AND METHOD AND APPARATUS FOR DETERMINING INTRA PREDION MODE OF IMAGE DECODING UNIT

摘要

A method and apparatus for determining an intra prediction mode of a coding unit. Candidate intra prediction modes of a chrominance component coding unit, which includes an intra prediction mode of a luminance component coding unit, are determined, and costs of the chrominance component coding unit according to the determined candidate intra prediction modes are compared to determine a minimum cost intra prediction mode to be the intra prediction mode of the chrominance component coding unit.
