Abstract:
(EN) The present invention displays multiple images at different locations in the depth direction, while suppressing a decline in the resolution of each image, using projected light emitted from a single projector. A projector 20 emits first projection light L1 and first projection light L1 that have a first projection distance P1. The projection distance P of the second projection light L2 is shortened to a second projection distance P2 that is shorter than the initial first projection distance P1, by positioning a projection distance shortening unit 25 having a positive refractive power along the path of the second projection light L2 between the projector 20 and a second screen 24. Furthermore, no optical members having a negative refractive power are positioned along the optical path of the first projection light L1 from the projector 20 to a first screen 23 on the projector 20 side relative to the second screen 24.
(FR) La présente invention affiche de multiples images à différents emplacements dans le sens de la profondeur, tout en empêchant une baisse de la résolution de chaque image, à l'aide d'une lumière projetée émise depuis un seul projecteur. Un projecteur (20) émet une première lumière de projection (L1) et une première lumière de projection (L1) qui présentent une première distance de projection (P1). La distance de projection (P) de la seconde lumière de projection (L2) est raccourcie à une seconde distance de projection (P2) qui est plus courte que la première distance de projection initiale (P1) en positionnant une unité de raccourcissement de la distance de projection (25) ayant une réfringence positive le long du trajet de la seconde lumière de projection (L2) entre le projecteur (20) et un second écran (24). En outre, aucun élément optique ayant une réfringence négative n'est positionné le long du trajet optique de la première lumière de projection (L1) provenant du projecteur (20) jusqu'à un premier écran (23) côté projecteur (20) par rapport au second écran (24).
(JA) 1つの投射器から出射される投影光により、奥行き方向の異なった位置に複数の画像をそれぞれ解像度の低下を抑えて表示する。 投影器20は、第1の投影距離P1を有する第1投影光L1と第1投影光L1とを出射し、正の屈折力を有する投影距離短縮部25を、投影器20と第2スクリーン24との間の第2投影光L2の経路上に配置することで、第2投影光L2の投影距離Pを初期の第1投影距離P1よりも短い第2投影距離P2に短縮し、投影器20から第1スクリーン23までの第1投影光L1の光路は、第2スクリーン24よりも投影器20側において、負の屈折力を有する光学部材を配置しない。
