Abstract

Se describe un dispositivo de codificación de imagen que incluye una unidad de predicción 4 para determinar de manera adaptativa el tamaño de cada bloque de unidad de predicción de movimiento de acuerdo con señales de componente de color, y para dividir cada bloque de unidad de predicción de movimiento en regiones de asignación de vector de movimiento para buscar un vector de movimiento, y una unidad de codificación de longitud variable 8 para, cuando un vector de movimiento es asignado a cada bloque de unidad de predicción de movimiento completo, realizar codificación en modo mc_skip si el vector de movimiento es igual a un vector estimado y una señal de error de predicción 5 no existe, y para, cuando cada región de asignación de vector de movimiento tiene un tamaño igual a o más grande que un tamaño predeterminado y un vector de movimiento es asignado a cada región de asignación de vector de movimiento completa, realizar codificación en modo sub_mc_skip si el vector de movimiento es igual a un vector estimado y una señal de error de predicción 5 no existe.
