Abstract
Disclosed are a method and a device by which individual images can be displayed simultaneously to a plurality of observers. In this process, projectors can be used that project the colors from which the images are assembled following one another periodically in time.
Claims15
A method for the simultaneous projection of individual images for a plurality M of viewers,
- wherein each image Bm, m=1, M, is respectively either a partial image Tm a, a ϵ{left, right} for a right eye and a left eye of the viewer m for a viewer m or is
- a partial image Tm a=both for both eyes of a viewer m;
- wherein each partial image Tm a is assembled from N, Nϵ and N≥2, color components Fm a c, c=1, . . . , N of different colors;
- wherein N projectors Pn, n=1, . . . , N, in each case project color components of the part images in temporally consecutive time intervals ti;
- wherein each projector projects all N colors of color components periodically temporally in a fixed order after one another;
- wherein the N projectors together project all color components Fm a c, c=1, . . . , N, of a partial image Tm a for one or both eyes a of one of the viewers m in every time interval ti;
- and project all the partial images Tm a of both eyes a of all the viewers m once in the course of a period;
- wherein a filter that can be switched between transparent and opaque is assigned to each eye a, a ϵ (left, right, both) of each viewer;
- and
- wherein the respective filter assigned to the eye a of the viewer m is switched to transparent in the time interval ti in which the projectors display the color components of the partial image Tm a.
