Resumen
La luz azul presente en los dispositivos móviles tienen una función reguladora del organismo en procesos como el sueño o el hambre. Además, la exposición directa está asociada con el desarrollo o empeoramiento de ciertas enfermedades y para las personas con alguna afección específica puede resultar molesta y peligrosa. Muchos dispositivos del mercado poseen sistemas de filtrado para atajar esta situación, pero modifican significativamente la mayoría de colores. Este trabajo propone un nuevo procedimiento para reducir la representación de color o Gamut de la pantalla correspondiente a las emisiones más energéticas, para poder evitarlas. El resultado llega a absorciones del 100%, respetando el contraste, la calidad y la mayor parte de colores de la imagen, consiguiendo un resultado lo más realista posible. La propuesta se considera de interés para su aplicación en tiempo real en dispositivos de proyección de vídeo, como por ejemplo los dispositivos de realidad aumentada y virtual.
