Rendering composite content on a head-mounted display including a high resolution inset
First Claim
1. A method comprising:
- dividing an image into a high resolution (HR) inset portion, a peripheral portion, and a transitional portion between the HR inset portion and the peripheral portion, wherein the HR inset portion is at a first resolution, and the transitional portion has an inner boundary between the transitional portion and the HR inset portion and an outer boundary between the transitional portion and the peripheral portion, wherein the peripheral portion is at a second resolution that is lower than the first resolution;
blending the transitional portion of the image such that there is a smooth change in resolution from the inner boundary at the first resolution to the outer boundary at the second resolution;
generating an inset region using the HR inset portion of the image and the blended transitional portion of the image; and
providing, for display, the inset region and a background region to a display.

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.

10. A non-transitory computer-readable storage medium storing executable computer program instructions, the instructions executable to perform steps comprising:
-
dividing an image into a high resolution (HR) inset portion, a peripheral portion, and a transitional portion between the HR inset portion and the peripheral portion, wherein the HR inset portion is at a first resolution, and the transitional portion has an inner boundary between the transitional portion and the HR inset portion and an outer boundary between the transitional portion and the peripheral portion, wherein the peripheral portion is at a second resolution that is lower than the first resolution; blending the transitional portion of the image such that there is a smooth change in resolution from the inner boundary at the first resolution to the outer boundary at the second resolution; generating an inset region using the HR inset portion of the image and the blended transitional portion of the image; and providing, for display, the inset region and a background region to a display. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A head-mounted display (HMD) comprising:
-
a controller configured to; divide an image into a high resolution (HR) inset portion, a peripheral portion, and a transitional portion between the HR inset portion and the peripheral portion, wherein the HR inset portion is at a first resolution, and the transitional portion has an inner boundary between the transitional portion and the HR inset portion and an outer boundary between the transitional portion and the peripheral portion, wherein the peripheral portion is at a second resolution that is lower than the first resolution, blend the transitional portion of the image such that there is a smooth change in resolution from the inner boundary at the first resolution to the outer boundary at the second resolution, generate an inset region using the HR inset portion of the image and the blended transitional portion of the image, and provide, for display, the inset region and a background region to a display; and an optics block configured to; combine the inset region and the background region to create composite content, wherein the inset region is inset into the background region, and direct the composite content to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD. - View Dependent Claims (20)
