Abstract

Un sistema de codificación de imagen para codificar una imagen digital que comprende: medios para codificar cada uno de los bloques en los que está dividida una imagen, medios de intra-predicción para predecir un valor de píxel de un bloque objetivo a ser codificado mediante el uso de al menos un valor de píxel de un bloque adyacente al bloque objetivo, y medios de estimación del modo de predicción para estimar un modo de predicción para el bloque objetivo; en el que los medios de intra-predicción incluyen un modo de predicción vertical utilizando un valor de predicción que es un valor de píxel de un primer bloque localizado junto y por encima del bloque objetivo; un modo de predicción horizontal utilizando un valor de predicción que es un valor de píxel de un segundo bloque situado junto a la izquierda del bloque objetivo; un modo de predicción DC utilizando un valor de predicción que es un promedio de los valores de píxel de los bloques primero y segundo; un modo de predicción diagonal abajo/izquierda utilizando la dirección especificada que es diagonalmente hacia abajo a la izquierda a aproximadamente un ángulo de 45 grados desde la horizontal; un modo de predicción diagonal abajo/derecha utilizando la dirección especificada que es diagonalmente hacia abajo a la derecha a aproximadamente un ángulo de 45 grados desde la horizontal; un modo de predicción vertical derecho utilizando la dirección especificada que es diagonalmente hacia abajo a la derecha a aproximadamente un ángulo de 67,5 grados desde la horizontal; una predicción horizontal hacia abajo utilizando la dirección especificada que es diagonalmente hacia abajo a la derecha a aproximadamente un ángulo de 22,5 grados desde la horizontal; un modo de predicción vertical utilizando la dirección especificada que es diagonalmente hacia abajo a la izquierda a aproximadamente un ángulo de 67,5 grados desde la horizontal; y un modo de predicción horizontal arriba utilizando la dirección especificada que está diagonalmente hacia arriba a la derecha a aproximadamente un ángulo de 22,5 grados desde la horizontal; los modos de predicción son numerados con números crecientes en serie, en el orden del modo de predicción vertical, el modo de predicción horizontal, el modo de predicción DC, el modo de predicción diagonal abajo/izquierda, el modo de predicción diagonal abajo/derecha; el modo de predicción vertical derecho; el modo de predicción horizontal hacia abajo; el modo de predicción vertical izquierdo y el modo de predicción horizontal arriba y los medios de estimación del modo de predicción determinan que un modo de predicción tiene el menor número de modo entre el modo de predicción del primer bloque y el modo de predicción del segundo bloque como el modo de predicción para el bloque objetivo; y los medios de intra-predicción codifican la primera información y la segunda información; la primera información muestra si un modo de predicción real es igual o no al modo de predicción que se ha estimado en los medios de estimación; y la segunda información está codificada en un caso donde el modo de predicción real es diferente del modo de predicción que se ha estimado en los medios de estimación para mostrar el modo de predicción real; en el que la segunda información es una referencia al orden de modo de un conjunto de modos de predicción reordenados realizada eliminando el modo de predicción estimado por los medios de estimación del grupo ordenado.
