Abstract

La presente tecnología pertenece a un dispositivo de codificación, método de codificación, dispositivo de descodificación, y método de descodificación que permiten el intercambio o predicción de información que pertenece a una imagen de referencia de una imagen que tiene una estructura de varias capas. Una unidad de codificación de mejora establece la información de generación de especificación de imagen de referencia utilizada para generar información que especifica la imagen de referencia de una imagen de mejora utilizando información que especifica la imagen de referencia como información que pertenece a la imagen de referencia de una imagen de base y la información que especifica la imagen de referencia como la información que pertenece a la imagen de referencia utilizada cuando se codifica la imagen de mejora. La unidad de codificación de mejora codifica la imagen de mejora utilizando la imagen de referencia, generando datos codificados. Una unidad de transmisión transmite los datos codificados y la información de generación de especificación de imagen de referencia. La presente tecnología, por ejemplo, puede aplicarse a un dispositivo de codificación.
