摘要： The invention relates to an illuminating device comprising an optical source emitting an unpolarized light beam, a polarizing beam splitter comprising a grid polarizer situated between the faces of two prisms. The light beam penetrates into the first prism through a face and reaches the polarizing beam splitter that transmits the light having a first polarization direction to the face that reflects it toward an exit face. In addition, the splitter reflects the light having a second polarization direction to the face that reflects it toward an exit face. Application: Display and projection systems

摘要： Method to display an image using four or more primaries having different spectral distributions that are distributed into three groups of primaries, wherein, in a visual color space, all primaries belonging to the same group have the same visual color and are metamehc. Each image being got from a combination of three primary images and each primary image being associated with each visual color of a group, the different primaries of each group are spatially or sequentially distributed over the primary image associated with this group, then allowing an efficient anti-copy protection based on metamerization of images, without any supplemental video processing.
