Abstract

L'invention a trait à un procédé de partage de ressources d'appareils de prise de vues, comprenant : la surveillance d'applications ; la création d'un identifiant unique pour une application demandant à appeler une ressource de données pour identifier l'application ; puis le mappage d'un canal virtuel correspondant pour l'application à identifiant unique afin de mettre en œuvre une interaction de données avec un module de prise de vues. L'invention concerne également un dispositif de partage de ressources d'appareils de prise de vues, comportant : un module de surveillance permettant de surveiller des applications s'exécutant sur un module d'applications ; un module de classement servant à identifier et classer des identifiants d'applications ; un module de canal de données destiné à créer un canal virtuel d'appareil de prise de vues unique correspondant ; et un module d'appel de données permettant d'extraire des ressources de données. Au moyen de ce procédé et de ce dispositif, des ressources, des logiques et des données sont séparées, la structure est simplifiée, la complexité de développement est nettement réduite et la répétabilité de code est limitée. De plus, des comportements d'interface ou autres sont dans une même table de données, de telle sorte qu'une personne qui ne comprend pas les programmes peut apporter des modifications.
