Abstract

La invención se relaciona con un método para procesar imágenes de video que comprende los siguientes pasos para: - adquirir una pluralidad de imágenes de video durante un intervalo de tiempo que comprende un tiempo de referencia t, - asociar un factor de ponderación con cada una de las imágenes de video, teniendo al menos dos de las imágenes de video diferentes factores de ponderación, - memorizar las imágenes de video, - ponderar cada una de las imágenes de video memorizadas, con el factor de ponderación asociado, - generar una imagen llamada imagen de referencia asociada con el tiempo de referencia t promediando las imágenes de video ponderadas. De acuerdo con la invención, cada imagen de video es memorizada con una resolución proporcional al factor de ponderación asociado con la imagen de video para reducir el espacio de memoria necesario para el almacenamiento de imágenes y reducir el tiempo de acceso de las imágenes memorizadas.
