Abstract
(EN)
A method and a system for displaying images, and an image display apparatus for use thereof are described. An image display apparatus, for example, a projector (12) is controlled by a mobile apparatus, for example, a PDA (14) in such a way that the image display apparatus (12) generates images, preferably a presentation file, for example, in PowerPoint format and reproduces and displays the corresponding images. A representation of a displayed image is transmitted to the mobile apparatus (14) in which it is displayed.

L'invention concerne un procédé et un système d'affichage d'images ainsi qu'un appareil d'affichage d'images à utiliser dans ce système. Selon cette invention, un appareil d'affichage d'images, par exemple un projecteur (12), est commandé par un appareil mobile, par exemple un assistant numérique personnel (14), de sorte que cet appareil d'affichage d'images (12) génère des images, de préférence un fichier de présentation par exemple au format PowerPoint, puis reproduit et affiche les images correspondantes. Une représentation d'une image affichée est transmise audit appareil mobile (14) dans lequel elle est affichée.
