Abstract
En las formas de realización de la presente solicitud se describen un método de codificación/decodificación de imágenes, un codificador, un decodificador y un medio de almacenamiento. El método de codificación comprende: el codificador determina un tamaño del bloque actual; cuando el bloque actual se codifica usando un modo MIP, determina un primer desplazamiento de acuerdo con el tamaño del bloque actual; calcula un segundo desplazamiento utilizando el primer desplazamiento y un valor de reconstrucción de un píxel adyacente correspondiente al bloque actual; determina un primer valor de predicción del bloque actual de acuerdo con el segundo desplazamiento; y realiza la codificación en el bloque actual sobre la base del primer valor de predicción. El método de decodificación comprende: el decodificador analiza un flujo de código para obtener un tamaño del bloque actual y un modo de codificación; cuando el modo de codificación del bloque actual es un modo MIP, determina un primer desplazamiento de acuerdo con el bloque actual; calcula un segundo desplazamiento utilizando el primer desplazamiento y un valor de reconstrucción de un píxel adyacente correspondiente al bloque actual; determina un primer valor de predicción del bloque actual de acuerdo con el segundo desplazamiento; y determina un valor de reconstrucción del bloque actual sobre la base del primer valor de predicción.
