Abstract

El Ajuste de Rango Dinámico se puede utilizar para corregir distorsiones que pueden ocurrir cuando se transforma el rango dinámico de los colores en video; en diversos ejemplos, el Ajuste de Rango Dinámico puede ser ejecutado utilizando una función lineal a nivel de pieza que toma como entrada un rango de valores de color; parámetros que describen la función lineal a nivel de pieza pueden ser codificados en una corriente de bits, y los parámetros pueden ser utilizados por un proceso de decodificación para reconstruir la función lineal a nivel de pieza; para mejorar la eficiencia de la codificación, se pueden aplicar técnicas a través de las cuales valores redundantes en los parámetros no necesitan ser codificados cuando el rango de valores de entrada para la función lineal a nivel de pieza puede ser dividido en porciones que tienen iguales longitudes; el proceso de decodificación puede derivar los valores omitidos de los valores que son proporcionados, y puede aplicar la función lineal a nivel de pieza a datos de video decodificados para ejecutar Ajuste de Rango Dinámico.
