Abstract

La présente invention concerne un procédé et un appareil de conversion d'image. Des informations d'image originales (les informations d'image originales comprennent divers éléments d'informations d'opération de dessin pour générer une image 3D simple image à présenter) de l'image 3D simple image à présenter dans d'un logiciel 3D simple image sont obtenues, et ensuite une première image à présenter et une seconde image à présenter sont générées par utilisation des informations d'opération de dessin pour servir d'image 3D double image à présenter correspondant à l'image 3D simple image, de manière à mettre en œuvre le processus de conversion de l'image 3D simple image à présenter en une image 3D double image à présenter, et à éviter le problème qui est que, dans l'état de la technique, le logiciel 3D simple image doit être redéveloppé/modifié avant de pouvoir obtenir l'effet de présentation stéréoscopique du logiciel 3D simple image par un visiocasque.
