Abstract
Cuando un parámetro de intra-predicción indica un proceso de predicción horizontal, una unidad de intra-predicción añade un valor proporcional a un cambio en una dirección horizontal de los valores de luminancia de píxeles adyacentes a la parte superior de cada bloque, que es una unidad para el proceso de predicción de un bloque de codificación, al valor de luminancia de un píxel adyacente a la izquierda del bloque para fijar un resultado de la adición como un valor predicho de una imagen de predicción, mientras que cuando el parámetro de intra-predicción indica un proceso de predicción vertical, la unidad de intra-predicción añade un valor proporcional a un cambio en una dirección vertical de los valores de luminancia de píxeles adyacentes a la izquierda del bloque al valor de luminancia del pixel adyacente a la parte superior del bloque para fijar el resultado de la adición como un valor predicho de la imagen de predicción.
