Abstract
(EN)
An exposure apparatus of projection type and exposure method in which the distribution of quantity of light on the exposure surface of a luminous flux modulated by a light bulb to which uniform data is given is found, image data is corrected according to the distribution used as correction data so as to create exposure data. The luminous flux projected onto the exposure surface forms a projection image reflecting the distribution determined by factors such as the exposure apparatus, and an image with less uneven distribution of quantity of light is exposed onto a medium placed on the exposure surface. A printer incorporating such an exposure apparatus can output a color print with less color unevenness at high speed.
(FR)
L'invention concerne un appareil d'exposition du type projection et un procédé d'exposition dans lequel on attribue des données uniformes à la répartition de la lumière sur la surface d'exposition d'un flux lumineux, modulée par une ampoule électrique. Les données d'images sont corrigées en fonction de la répartition utilisée comme données de correction de manière à créer des données d'exposition. Le flux lumineux projeté sur la surface d'exposition forme une image de projection qui réfléchit la répartition déterminée par des facteurs tels que l'appareil d'exposition. Une image avec une répartition non homogène moins importante de la lumière est exposée sur un support placé sur la surface d'exposition. Une imprimante intégrant cet appareil d'exposition peut produire une impression couleur avec une absence d'homogénéité de couleur moins importante et une vitesse élevée.
