Abstract
Una modalidad de la presente invención establece una técnica para corregir valores de color. La técnica incluye reducir el muestreo de valores de espacio en unos primeros valores de espacio de color para generar valores de espacio de color reducidos en muestro y aumentar el muestreo de los valores de espacio de color reducidos en muestreo para generar unos segundos valores de espacio de color. La técnica incluye además modificar al menos un valor de componente incluido en los valores de espacio de color reducidos en muestro basado en un primer valor de componente incluido en los primeros valores de espacio de color, un segundo valor de componente incluido en los segundos valores de espacio de color y una aproximación de una función de transferencia no lineal.
