Patent

CA 2108851

The present invention relates to a method of enhancing a digital color video image comprised of separating a source pixel into individual component parts, for each component part, generating a random number having the same length as the corresponding component part, adding each random number to its corresponding component part to form resultant component parts, and combining the resultant component parts to form a destination pixel.

La présente invention est une méthode d'amélioration de la qualité des images vidéo numériques en couleurs qui consiste à séparer un pixel source en composantes et, pour chaque composante, à produire un nombre aléatoire de même longueur que cette composante, à ajouter chaque nombre aléatoire à la composante correspondante pour former une composante résultante, et à combiner les composantes résultantes pour former un pixel de destination.
