Patent

CA 2237265

Image data having a plurality of pixel is processed. Each pixel is represented by three color components (RGB) defining a position within color-space. A base color is identified and a distance in color-space between an input color and said base color is calculated. A control value, which may be used as a basis for a chroma-suppress or a chroma-key etc, is produced in response to the calculated distance.

Des données d'image ayant plusieurs pixels sont traitées. Chaque pixel est représenté par des composantes tricolores (RVB) définissant une position dans un espace de couleur. Une couleur de base est identifiée et une distance dans un espace de couleur, entre une couleur d'entrée et ladite couleur de base, est calculée. Une valeur de commande qui peut être utilisée comme base à la suppression de chrominance ou à l'incrustation couleur, est produite en réponse à la distance calculée.
