Title (EN) PROJECTION DEVICE
(FR) DISPOSITIF DE PROJECTION
(JA) 投影装置
Abstract:
(EN) Provided is an image capture device comprising the following: a shared section 20 which is used in common by a projection optical system T1 and an image capture optical system T2; a projection-dedicated part 30 which is used only by the projection optical system T1; an image capture-dedicated part 40 which is used only by the image capture optical system T2; and an illumination optical system 10 for illuminating an image display element 31. The shared section 20 includes a projection lens group 21, an optical path splitting element 22, and an aperture stop ST for determining the F-number of the image capture optical system T2. The projection-dedicated part 30 includes the image display element 31. The image capture-dedicated part 40 includes an image capture element 41. The illumination optical system 10 includes a brightness control unit 13 for determining the F-number of the projection optical system T1. The maximum value of the light-flux diameter of image capture light which passes through the aperture stop ST is larger than the maximum value of the light-flux diameter of the projection light which passes through the aperture stop ST.
(FR) Dispositif de capture d'image, comprenant : une section partagée 20 utilisée en commun par un système optique de projection T1 et un système optique de capture d'image T2 ; une partie dédiée à la projection 30 utilisée uniquement par le système optique de projection T1 ; une partie dédiée à la capture d'image 40 utilisée uniquement par le système optique de capture d'image T2 ; et un système optique d'éclairage 10 destiné à éclairer un élément d'affichage d'image 31. La section partagée 20 comporte un groupe de lentilles de projection 21, un élément diviseur de trajet optique 22 et un diaphragme d'ouverture ST destiné à établir le nombre F du système optique de capture d'image T2. La partie dédiée à la projection 30 comporte l'élément d'affichage d'image 31. La partie dédiée à la capture d'image 40 comporte un élément de capture d'image 41. Le système optique d'éclairage 10 comporte une unité de réglage de la luminosité 13 destinée à établir le nombre F du système optique de projection T1. La valeur maximale du diamètre de flux lumineux de la lumière de capture d'image qui passe à travers le diaphragme d'ouverture ST est supérieure à la valeur maximale du diamètre de flux lumineux de la lumière de projection qui passe à travers la membrane d'ouverture ST.
(JA) 撮像蔵置は、投影光学系T1と撮像光学系T2とに共通で使用される共用部20と、投影光学系T1にのみ使用される投影専用部30と、撮像光学系T2にのみ使用される撮像専用部40と、画像表示素子31を照明する照明光学系10とを備える。共用部20は投影レンズ群21と、光路分離素子22と、撮像光学系T2のFナンバーを決定する開口絞りSTとを有し、投影専用部30は、画像表示素子31を有し、撮像専用部40は、撮像素子41を有し、照明光学系10は、投影光学系T1のFナンバーを決定する明るさ制御部13を有する。開口絞りSTを通過する撮像光の光束径の最大値は、開口絞りSTを通過する投影光の光束径の最大値より大きい。
