Title
(EN) PROJECTOR SYSTEM
(FR) SYSTÈME DE PROJECTEUR
(JA) プロジェクタシステム
Abstract
(EN)
A projector system (1) provided with a plurality of projectors (10) each projecting a video onto a curved, translucent projection screen (30) with a rear-side that appears convex to a user, wherein a controller (20) divides an input video into a plurality of videos each having an overlapped region to thereby supply the plurality of divided videos to the plurality of projectors (10) respectively. The optical axes of projected light rays from the plurality of projectors (10) have an intersection at a position further away from the plurality of projectors (30) than the center of the curved screen (30).
(FR)
La présente invention concerne un système de projecteur (1) qui comprend une pluralité de projecteurs (10) projetant chacun une vidéo sur un écran de projection translucide incurvé (30) doté d'un côté arrière qui apparaît convexe pour un utilisateur, un dispositif de commande (20) divisant une vidéo d'entrée en une pluralité de vidéos ayant chacune une région de chevauchement pour ainsi fournir la pluralité de vidéos divisées à la pluralité de projecteurs (10) respectivement. Les axes optiques des rayons lumineux projetés à partir de la pluralité de projecteurs (10) ont une intersection à une position plus éloignée de la pluralité de projecteurs (30) que le centre de l'écran incurvé (30).
(JA)
ユーザから見て背面側が凸の透過型の曲面スクリーン(30)に、それぞれ映像を投影する複数のプロジェクタ装置(10)を備えるプロジェクタシステム(1)において、制御部(20)は、入力映像を、それぞれ重複領域を持たせて複数の映像に分割し、分割した複数の映像を複数のプロジェクタ装置(10)にそれぞれ供給する。複数のプロジェクタ装置(10)の各投射光の光軸は、曲面スクリーン(30)の中心点よりも複数のプロジェクタ装置(30)から見て遠方の位置を交点とする。
