Abstract
A display apparatus including means for detecting gaze direction of user; first and second image renderers; processor, processor or external processor processes input image to generate first image and second image, processor renders first and second images simultaneously; configuration of reflective elements arranged to split light emanating from second image renderer into plurality of directions to produce plurality of projections of second image in tiled layout; optical combiner; and opacity mask that is controlled based upon gaze direction to selectively allow given portion of the projections to pass through towards optical combiner, whilst blocking remaining portion of projections. Optical combiner is arranged to optically combine projection of first image with given portion of the projections, to produce on image plane an output image.
