Abstract
Examples disclosed herein obtain first image data and the second image data for a foveated image frame to be displayed on a display, the first image data to have a first resolution and the second image data to have a second resolution lower than the first resolution. Disclosed examples also up-sample the second image data based on first metadata to generate up-sampled second image data, the up-sampled second image data to have the first resolution, and combine the first image data and the up-sampled second image data based on second metadata. Disclosed examples further perform, based on third metadata, a combination of at least two different filter operations on an overlap region including a portion of the first image data and a portion of the up-sampled second image data to generate the foveated image frame, the third metadata to specify a width in pixels of the overlap region.
