Abstract
(EN)
There are provided a spatial light modulation device and a projector capable of obtaining smooth image quality so that an observer does not recognize any light shading portion such as a black matrix. The projector includes a spatial light modulation device (110R) for modulating the incident light according to an image signal and emitting the modulated result and a prism group (210) arranged at the emission side of the spatial light modulation device (110R). The spatial light modulation device (110R) has an opening (230) as a plurality of pixel portions arranged in a matrix and a black matrix (220) arranged between them. The prism group (210) consists of a prism element (211) having at least a refraction surface (212). Light from one opening (230) is introduced into at least a part of the prism group (210). The direction of the refraction surface and the inclination angle ϑ are defined so as to introduce an opening image (230P) onto a black matrix portion image (220P) on a screen (116) at a predetermined distance L from the prism group (210).

L'invention porte sur un modulateur spatial de lumière et sur un projecteur capable d'obtenir une qualité d'image lissée de sorte qu'un observateur ne reconnaisse aucune partie d'ombrage telle qu'une matrice noire. Le projecteur comprend un modulateur spatial de lumière (110R), destiné à moduler la lumière incidente conformément à un signal d'image et à émettre le résultat modulé, et un groupe de prismes (210) arrangé du côté émission du modulateur (110R). Le modulateur spatial de lumière (110R) comporte une ouverture (230) se présentant sous forme d'une pluralité de parties de pixels agencés dans une matrice et entre lesquels est placée une matrice noire (220). Le groupe de prismes (210) comprend un élément de prisme (211) ayant au moins une surface de réfraction (212). La lumière provenant d'une ouverture (230) est introduite dans au moins une partie du groupe de prismes (210). On définit le sens de la surface de réfraction et l'angle d'inclinaison ϑ de façon à introduire une image d'ouverture (230P) sur une image d'une partie de la matrice noire (220P) sur un écran (116) à une distance prédéterminée L du groupe de prismes (210).
