Abstract

Un método de codificación de imágenes en movimiento incluye: codificar un bloque objetivo de codificación utilizando un vector de movimiento; generar una pluralidad de predictores de vectores de movimiento; y codificar el vector de movimiento utilizando uno de la pluralidad de predictores de vectores de movimiento generados en la generación de una pluralidad de predictores de vectores de movimiento. En la generación de una pluralidad de predictores de vectores de movimiento, un vector de reemplazo que reemplaza un predictor temporal de vector de movimiento se agrega a la pluralidad de predictores de vectores de movimiento (S13, S14) cuando es imposible obtener el predictor temporal de vector de movimiento a partir de un bloque el cual está incluido en una imagen codificada diferente de la imagen objetivo de codificación y corresponde al bloque objetivo de codificación (S12).
