generating images to be projected at different projection distances with a multi - aperture projection display , statically or without any conversion , neither mechanically nor at the imager , is enabled by designing the single images of the multi - aperture projection display in a suitable manner , namely by combining provisional single images for the projection channels of the multi - aperture projection display , which are intended for each of the at least two images to be projected , projection channel by projection channel , to the actual or final single images .
