Abstract
En este dispositivo de decodificación de imágenes, una unidad de generación de candidatos a modo de predicción genera una primera lista de candidatos a modo de intra predicción y una segunda lista de candidatos a modo de intra predicción a partir de un modo de intra predicción de un bloque adyacente a un bloque que será predicho. Una unidad de selección de modos de predicción selecciona un primer modo de intra predicción y un segundo modo de intra predicción de la primera lista de candidatos a modo de intra predicción y la segunda lista de candidatos a modo de intra predicción, respectivamente. Una unidad de cálculo de valores de predicción calcula, sobre la base del primer modo de intra predicción, un primer valor de predicción de un pixel decodificado adyacente al bloque que se va a predecir, y calcula, sobre la base del segundo modo de intra predicción, un segundo valor de predicción de un pixel decodificado adyacente al bloque que se va a predecir. Una unidad de ponderación de valores de predicción calcula un tercer valor de predicción sobre la base del primer valor de predicción y el segundo valor de predicción.
