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 image is at a first resolution corresponding to a resolution of a fovea region of a human eye, 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;
downsampling the peripheral portion to a second resolution that is less than the first resolution, the second resolution corresponding to a resolution of a non-fovea region of the human eye;
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, the smooth change corresponding to a change in resolution between the fovea region and the non-fovea region;
generating an inset region using the HR inset portion of the image and the blended transitional portion of the image;
generating a background region using the downsampled peripheral portion;
providing, for display, the inset region to a HR inset display on a head-mounted display (HMD);
providing, for display, the background region to a peripheral display on the HMD, andwherein an optics block combines the displayed inset region with the displayed background region to generate composite content.

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.

9. 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 image is at a first resolution corresponding to a resolution of a fovea region of a human eye, 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; downsampling the peripheral portion to a second resolution that is less than the first resolution, the second resolution corresponding to a resolution of a non-fovea region of the human eye; 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, the smooth change corresponding to a change in resolution between the fovea region and the non-fovea region; generating an inset region using the HR inset portion of the image and the blended transitional portion of the image; generating a background region using the downsampled peripheral portion; providing, for display, the inset region to a HR inset display on a head-mounted display (HMD); providing, for display, the background region to a peripheral display on the HMD, and wherein an optics block combines the displayed inset region with the displayed background region to generate composite content. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. 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 image is at a first resolution corresponding to a resolution of a fovea region of a human eye, and the transitional portion has an inner boundary between the transitional portion and the HR inset portion and an outer boundary between the transitional region and the peripheral portion, downsample the peripheral portion to the second resolution, the second resolution corresponding to a resolution of a non-fovea region of the human eye, 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, the smooth change corresponding to a change in resolution between the fovea region and a non-fovea region of the human eye, generate an inset region using the HR inset portion of the image and the blended transitional portion of the image, generate a background region using the downsampled peripheral portion; and a high resolution (HR) inset display that is configured to display the inset region; a peripheral display that is configured to display the background region; 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 (18, 19, 20, 21, 22)
