Abstract

Selon l'invention, afin de mettre en œuvre un affichage tridimensionnel (3D) de dessus de table, une image en position droite sur un affichage en forme de dessus de table est représentée à l'aide d'une zone de sous-visualisation (SVZ) pour être restituée par une lentille élémentaire autre qu'une lentille élémentaire correspondante. Par conséquent, la présente invention a des effets remarquables consistant à : permettre la couverture des deux yeux du fait que la présente invention a une forme de dessus de table telle que les deux yeux sont sur le même axe ; permettre d'améliorer la qualité d'image d'une image restituée à l'aide d'une technique d'affichage d'image intégrée utilisant un réseau de lentilles et à l'aide d'un champ visuel de degré élevé pour configurer l'affichage 3D de dessus de table, le champ visuel devenant toutefois plus étroit à mesure que le degré d'une zone de visualisation augmente ; et assurer un champ visuel en rattachant un prisme linéaire à un réseau de lentilles comme moyen pour régler un trajet optique.
