Abstract
Un dispositivo de codificación de imágenes incluye: una unidad de derivación de candidatos a vector de bloque que deriva candidatos a vector de bloque de un bloque objetivo de codificación en una imagen objetivo de codificación a partir de la información de codificación almacenada en una memoria de almacenamiento de información de codificación; un selector que selecciona un vector de bloque seleccionado a partir de los candidatos a vector de bloque; un almacén que almacena imágenes codificadas de un número predeterminado de bloques estándar de copia intra-bloque inmediatamente antes del bloque objetivo de codificación; y una unidad de corrección del límite de la región de referencia que elimina una imagen codificada de un bloque estándar de copia intra-bloque en el almacenamiento de una región referenciable después de la finalización de un proceso de codificación del bloque objetivo de codificación, y determina si una posición superior izquierda y una posición inferior derecha de un bloque de referencia indicado por el vector de bloque seleccionado están ambas incluidas en la región referenciable.
