Abstract
A head-mounted display (HMD) divides an image into a high resolution (HR) inset portion at a first resolution, a peripheral portion, and a transitional portion. The peripheral portion is downsampled to a second resolution that is less than the first resolution. The transitional portion is blended such that there is a smooth change in resolution that corresponds to a change in resolution between a fovea region and a non-fovea region of a retina. An inset region is generated using the HR inset portion and the blended transitional portion, and a background region is generated using the downsampled peripheral portion. The inset region is provided to a HR inset display, and the background region is provided to a peripheral display. An optics block combines the displayed inset region with the displayed background region to generate composite content.
