Abstract
Search is performed on Intra 16 to obtain a prediction mode leading to a minimum cost, and the minimum cost in Intra 16 and a corresponding prediction mode are stored. Search is performed on Intra 8 to obtain a prediction mode leading to a minimum cost, and then a relationship of magnitude between the stored minimum cost in Intra 16 and the minimum cost in Intra 8 is judged. After that, the minimum cost in Intra 8 and a corresponding prediction mode are stored, and search is performed on Intra 4 to obtain a prediction mode leading to a minimum cost. A relationship of magnitude between cost_intra and the minimum cost in Intra 4 is judged, and Intra 4 is determined as an optimum prediction mode in a case where Intra 4 is smaller.
