Apparatus for displaying still images to viewers in motion relative to those images, such as passengers on a subway train, includes a plurality of images mounted on a surface, and a slitboard mounted between that surface and the viewer. As the viewers pass by, the slitboard acts like a shutter, creating an animation effect. In addition, there is a stretching or widening effect that enlarges the images, allowing images to be "preshrunk," thereby allowing a large number of images in a small space, increasing the available frame rate of the animation. The stretching effect depends on the distance between the image surface and the slitboard.

La présente invention concerne un appareil d'affichage d'images fixes par rapport à un observateur en mouvement, tel qu'un passager du métropolitain, qui comprend un certain nombre d'images montées sur une surface et un panneau à fentes intercalé entre ces images et l'observateur. Pour l'observateur en mouvement, le panneau à fentes joue le rôle d'un obturateur et crée un effet d'animation. S'y ajoute un effet d'étirement ou d'élargissement qui agrandit les images et permet par là même d'utiliser des images de format réduit et en grand nombre dans un espace restreint, ce qui augmente le débit de plans d'animation disponibles. L'effet d'étirement dépend de la distance entre la surface de l'image et le panneau à fentes.
