Foveated image rendering for head-mounted display devices

At least one non-transitory computer readable medium comprising computer readable instructions that, when executed, cause at least one or more processors to at least:

• 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;
• 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;
• combine the first image data and the up-sampled second image data based on second metadata;
• and
• 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.

A method comprising:

• providing, with a first device, first image data and 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;
• up-sampling, with a second device, 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;
• combining, with the second device, the first image data and the up-sampled second image data based on second metadata;
• and
• performing, with the second device and 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.
