A method of and system for rendering a halftone image of a gray scale image (500) by utilizing a pixel-by-pixel comparison (402) of the gray scale image against a blue noise mask (502) is disclosed in which the gray scale image is scanned on a pixel-by-pixel basis and compared on a pixel-by-pixel basis to an array of corresponding data points contained in a blue noise mask stored in a PROM (406) or computer memory in order to produce the desired halftoned image. Both digital and optically implemented halftone methods are disclosed. Application specific modifications of the blue noise mask as well as its use for producing halftoned color images are also disclosed.

Méthode et système de rendu demi-tons d'une image à niveaux de gris (500) en comparant pixel par pixel (402) cette image avec un masque à bruit bleu (502), l'image à niveaux de gris étant balayée pixel par pixel et comparée pixel par pixel à une matrice de points de données correspondants contenus dans un masque à bruit bleu stocké dans une PROM (406) ou dans une mémoire d'ordinateur afin de produire l'image en demi-tons désirée. Des méthodes numériques et optiques de rendu demi-tons sont présentées, ainsi que des modifications d'application spécifique du masque à bruit bleu et de son utilisation dans la production d'images couleurs en demi-tons.
