Abstract:
(EN) The present invention displays multiple images at different locations in the depth direction, while suppressing a decline in display quality, using projected light emitted from a single projector. A projector 20 emits first projection light L1 and second projection light L2 that have a first projection distance P1. A projection distance lengthening unit 251 having a negative refractive power is positioned along the path of the first projection light L1 between the projector 20 and a first screen 23, and causes an image to be formed on the first screen 23 by lengthening the projection distance P of the first projection light L1. A projection distance shortening unit 252 having a positive refractive power is positioned along the path of the second projection light L2 between the projector 20 and a second screen 24, and causes an image to be formed on the second screen 24 by lengthening the projection distance P of the second projection light L2.
(FR) La présente invention affiche de multiples images à différents emplacements dans la direction de la profondeur, tout en supprimant une diminution de la qualité d'affichage, à l'aide d'une lumière projetée émise par un projecteur unique. Un projecteur (20) émet une première lumière de projection (L1) et une seconde lumière de projection (L2) qui ont une première distance de projection (P1). Une unité d'allongement de distance de projection (251) ayant une réfringence négative est positionnée le long du trajet de la première lumière de projection (L1) entre le projecteur (20) et un premier écran (23), et amène une image à être formée sur le premier écran (23) en allongeant la distance de projection (P) de la première lumière de projection (L1). Une unité de raccourcissement de distance de projection (252) ayant une réfringence positive est positionnée le long du trajet de la seconde lumière de projection (L2) entre le projecteur (20) et un second écran (24), et amène une image à être formée sur le second écran (24) en allongeant la distance de projection P de la seconde lumière de projection (L2).
(JA) 1つの投射器から出射される投影光で奥行き方向の異なった位置に複数の画像を、表示品位低下を抑えて表示する。 投影器20は、第1投影距離P1を有する第1投影光L1と第2投影光L2とを出射し、負の屈折力を有する投影距離延長部251は、投影器20と第1スクリーン23との間の第1投影光L1の経路上に配置し、第1投影光L1の投影距離Pを延長して第1スクリーン23に結像させ、正の屈折力を有する投影距離短縮部252は、投影器20と第2スクリーン24との間の第2投影光L2の経路上に配置し、第2投影光L2の投影距離Pを延長して第2スクリーン24に結像させる。
