Super-Resolution, Extended-Range Rendering for Enhanced Subpixel Geometry

Abstract:

Source content super-sampled to a first resolution in an extended range space is obtained. A representation of a subpixel geometry of a display panel displaying the source content is obtained. The display panel includes, for every pixel, plural subpixel elements for three or more color primaries. A native resolution of the display panel is lower than the first resolution of the source content. An optimization operation is performed based on a set mode of the display panel and the representation of the subpixel geometry to derive a global optimization for determining, for a given pixel value based on the source content, an energy distribution between the plurality of subpixel elements of a corresponding pixel of the display panel. The source content in the extended range space is converted into intermediate content in a display space based on the global optimization. The intermediate content is further optimized based on error minimization.
