Abstract

Una unidad de generación cambia la información del primer modo de predicción a la información del segundo modo de predicción según una combinación de una forma de un bloque objetivo de codificación en una imagen incluida en un vídeo y una forma de un bloque codificado que es adyacente al bloque objetivo de codificación; la primera información del modo de predicción es información del modo de predicción que indica un modo de intra predicción utilizado para codificar el bloque codificado; entonces, la unidad de generación genera información candidata que incluye un valor candidato para la información del modo de predicción, utilizando la segunda información del modo de predicción; una unidad de predicción genera un valor de píxel de intra predicción para el bloque objetivo de codificación en un modo de intra predicción prescrito; una primera unidad de codificación codifica el bloque objetivo de codificación utilizando el valor de píxel de intra predicción; una segunda unidad de codificación codifica la información del modo de predicción que indica el modo de intra predicción prescrito, utilizando la información candidata.
