Abstract

Un aparato de codificación de imágenes en movimiento (100) incluye una unidad de intra-inter predicción (107) que calcula un segundo vector de movimiento al llevar a cabo un proceso de escalamiento en un primer vector de movimiento de un bloque correspondiente temporalmente adyacente, cuando añade selectivamente, a una lista, un vector de movimiento de cada uno de uno o más bloques correspondientes cada uno de los cuales es ya sea un bloque incluido en una imagen actual que será codificada y espacialmente adyacente a un bloque actual que será codificado, o un bloque incluido en una imagen que no es la imagen actual y temporalmente adyacente al bloque actual, determina si el segundo vector de movimiento tiene una magnitud que está dentro de una magnitud predeterminada o no dentro de la magnitud predeterminada, y añade el segundo vector de movimiento a la lista cuando la unidad de intra-inter predicción determina que el segundo vector de movimiento tiene una magnitud que está dentro del intervalo de magnitud predeterminado.
