Dynamic Light Redistribution Algorithm Advancement for High-Dynamic Range Digital Projection

This project will investigate and develop advanced algorithms for high dynamic range projection using caustic image formation. These algorithms dynamically redirect light from dark image regions to bright regions, which addresses the problems of low peak luminance and poor black levels in current projectors. The algorithms will improve upon existing lensing methods by increasing computational efficiency and improving contrast. This project will produce viable algorithms for light redistribution in cinema projectors. This increases realism in film, resulting in projectors with lower capital/operating costs than existing approaches. The project will review and adapt existing methods for caustic image formation on MTT's prototype high dynamic range projector. The project will benefit MTT by allowing them to investigate a promising approach for light redistribution while drawing on the intern’s experience in computational displays. The intern will benefit from the internship by exposure to a new application area and gaining valuable work experience in an industrial start-up.
