Title (EN) INFORMATION DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE D'INFORMATIONS
(JA) 情報表示装置
Abstract:
(EN) The problem the present invention addresses is the provision of an information display device that is capable of showing a main image to specific viewers only and showing another image to other viewers. In order to do so, a brightness change unit (121) changes the brightness of a main image and another brightness change unit (122) generates a correction image in accordance with the difference between the main image and a secondary image. A projector (221) projects the main image onto a screen (24) through a polarizing filter (231), and another projector (222) projects the correction image onto the screen (24) through another polarizing filter (232). Specific viewers view the screen (24) using glasses (30) that have polarizing filters (31) exhibiting the same polarization direction as the abovementioned polarizing filter (231), and other viewers view the screen (24) without glasses.
(FR) Le but de la présente invention est de fournir un dispositif d'affichage d'informations qui soit capable de montrer une image principale à des spectateurs spécifiques uniquement, et de montrer une autre image à d'autres spectateurs. A cette fin, une unité de changement de luminosité (121) change la luminosité d'une image principale et une autre unité de changement de luminosité (122) génère une image de correction en fonction de la différence entre l'image principale et une image secondaire. Un projecteur (221) projette l'image principale sur un écran (24) par le biais d'un filtre polarisant (231), et un autre projecteur (222) projette l'image de correction sur l'écran (24) par le biais d'un autre filtre polarisant (232). Les spectateurs spécifiques regardent l'écran (24) en utilisant des lunettes (30) comportant des filtres polarisants (31) ayant la même direction de polarisation que le filtre polarisant (231) susmentionné, tandis que les autres spectateurs regardent l'écran (24) sans lunettes.
(JA)  本発明の課題は、特定の視聴者にのみ主画像を見せることができ、他の視聴者には他の画像を見せることができる情報表示装置を提供することにある。そのために、輝度変更部(12)は主画像の輝度を変更し、輝度変更部(12)は主画像と副画像の差に応じた補正画像を生成する。プロジェクタ(22)は、偏光フィルタ(23)を介して主画像をスクリーン(24)に投影し、プロジェクタ(22)は、偏光フィルタ(23)を介して補正画像をスクリーン(24)に投影する。特定の視聴者は、偏光フィルタ(23)と同じ変更方向の偏光フィルタ(31)を有するメガネ(30)を用いてスクリーン(24)を視聴し、他の視聴者は裸眼でスクリーン(24)を視聴する。
