Abstract

Se proporciona un dispositivo de codificación de imagen que divide una imagen en bloques y realiza la codificación para cada uno de los bloques divididos. Un divisor de bloque de señal primaria (101) divide una señal primaria de la imagen en rectángulos que tienen un tamaño predeterminado y genera un bloque de señal primaria. Un divisor de bloque de señal secundaria (101) divide una señal secundaria de la imagen en rectángulos que tienen un tamaño predeterminado y genera un bloque de señal secundaria. Un predictor de señal primaria (102) predice una señal primaria y un predictor de señal secundaria (102) predice una señal secundaria. El predictor de señal secundaria (102) puede realizar la interpredicción de la predicción de una señal secundaria de una señal codificada primaria y la interpredicción es restringida en función al menos de uno de un tamaño del bloque de señal primaria y un tamaño del bloque de señal secundaria.
