An omnidirectional image apparatus (130) for sensing an image of a substantially hemispherical scene from a single viewpoint, including a truncated, convex, substantially paraboloid-shaped reflector (135) positioned to orthographically reflect an image of the substantially hemispherical scene, and an image sensor (110) positioned to receive the orthographically reflected image. An omnidirectional image projection apparatus for projecting an image of a substantially hemispherical scene as viewed from a single viewpoint, including a means for projecting a collimated beam of light modulated with the image, and a truncated convex substantially paraboloid-shaped reflector positioned to orthographically reflect the collimated beam of light modulated with the image to project the hemispherical scene.

Cet appareil de projection omnidirectionnel (130) est destiné à capter une image d'une scène sensiblement hémisphérique, à partir d'un unique point de vue, et il comprend un réflecteur (135) sensiblement paraboloïde, convexe, tronqué et placé pour réfléchir de manière orthographique une image d'une scène sensiblement hémisphérique, ainsi qu'un capteur (110) d'images disposé pour recevoir l'image réfléchie de manière orthographique. On décrit un appareil de projection omnidirectionnel destiné à projeter une image d'une scène sensiblement hémisphérique telle que vue depuis un unique point de vue, cet appareil comprenant des moyens de projeter un faisceau collimaté de lumière modulée avec l'image, ainsi qu'un réflecteur sensiblement paraboloïde, convexe, tronqué et placé pour réfléchir de manière orthographique le faisceau collimaté de lumière modulée avec l'image, pour projeter la scène hémisphérique.
