Abstract

La présente invention a trait à un dispositif imageur qui permet de capturer une image tridimensionnelle en une seule fois grâce à une lentille unique et qui comprend une enveloppe (1), un demi-miroir (2), un miroir (3), un filtre de couleur verte (4) ainsi qu'un filtre de couleur rouge (5). Une ouverture (6) est pratiquée à l'avant de l'enveloppe (1), et une fenêtre de visée pour prise de vues (8), grâce à laquelle un dispositif appareil photo (7) peut prendre une photo, se situe à l'arrière de l'enveloppe (1). Le demi-miroir (2) est disposé de biais devant la fenêtre de visée pour prise de vues (8) dans l'enveloppe (1). Le miroir (3) est disposé de biais à un emplacement décalé par rapport au demi-miroir (2) dans l'enveloppe (1). Une surface réfléchissante (9) dudit miroir (3) se trouve en regard d'une surface arrière (10) du demi-miroir (2). Un filtre coloré (4) se situe sur une région relative (12) en regard d'une surface avant (11) du demi-miroir (2) dans l'ouverture (6). L'autre filtre coloré (5) se situe sur une région relative (13) en regard de la surface réfléchissante (9) du miroir (3) dans l'ouverture (6). Le dispositif imageur pallie les défauts de l'image tridimensionnelle capturée grâce à l'état de la technique analogue, où la largeur d'une image visuelle tridimensionnelle réelle représente exactement la moitié de la largeur d'une image de plan normal, ce qui aboutit généralement à un effet visuel médiocre ou à une difficulté d'adaptation.
