Abstract
Example methods, apparatus, systems and articles of manufacture (e.g., non-transitory physical storage media) to implement foveated image rendering for head-mounted displays device are disclosed herein. Example head-mounted display devices disclosed herein include a frame buffer to store first and second image data for an image frame, the first image data having a first resolution and the second image data having a second resolution lower than the first resolution, the first image data and the second image data obtained from a host device via a data interface. Disclosed example head-mounted display devices also include a device controller to up-sample the second image data based on first metadata from the host device to generate up-sampled second image data having the first resolution, and combine the first image data and the up-sampled second image data based on second metadata from the host device to render a foveated image frame on a display.
