Abstract

Un método de decodificación de imágenes en movimiento de acuerdo con la presente invención incluye: llevar a cabo intra predicción en un bloque objetivo para calcular valores de muestras predichas del bloque objetivo (S403); y calcular muestras reconstruidas del bloque objetivo al añadir datos de diferencia y los valores de las muestras predichas del bloque objetivo (S404), en donde en la realización de la intra predicción, se determina la validez de cada una de las muestras de referencia que se ubican una de inmediatamente arriba e inmediatamente a la izquierda del bloque objetivo, y cuando las muestras de referencia incluyen tanto una muestra de referencia válida como una muestra de referencia inválida, la intra predicción se lleva a cabo usando la muestra de referencia válida, y una muestra de referencia intra-predicha se determina como una muestra de referencia válida, y una muestra de referencia inter-predicha se determina como una muestra de referencia inválida.
