Abstract:
A display system, comprising:an optical system configured to project an image, where the image is formed using a plurality of pixels organized in lines to form a raster; an opto-mechanical system configured to continuously shift the direction of projection of the projected image, thus forcing each pixel of said image to circulate on a closed path; a pre-processor configured to generate a sequence of at least three projected images from a higher resolution image-file; wherein the pre-processor is configured to generate the individual pixels of the sequence of at least three projected images based on the anticipated location of the projected image at the time the individual pixel is refreshed; wherein the pre-processor is configured to progressively update the projected image, line after line, by refreshing the pixels in synchronism with the opto-mechanical system; wherein the optical system is configured to project a pixel throughout a refresh cycle until the pixel is refreshed using the corresponding pixel from the next image in the sequence of at least three projected images; and wherein the opto-mechanical system is configured so that the projected low resolution image occupies a new location each time a line of pixels refreshed by the pre-processor.
