US Patent 9720245 Content-adaptive lenticular prints

A lenticular display device that is effective in increasing both perceived angular resolution and spatial resolution. These desirable results are achieved by modifying the lenslet array to better match the content of a given light field. An optimization algorithm or method (which may be implemented with software run on a computing device) is provided that analyzes an input light field and computes an optimal lenslet size, shape, and arrangement of sets of lenslets across the width of the array to better (or even best) match the input light field given a set of output parameters. The resulting lenticular display device (or print) shows higher detail and smoother motion parallax compared with fixed-size lens arrays. The usefulness of these content-adaptive lenticular prints has been demonstrated or proven using rendered simulations, by generating 3D-printed lens arrays according to the present description, and with user studies.
