  • Gaze-driven autofocus camera for mixed-reality passthrough
    Patent number: 12547244
    Abstract: Particular embodiments are directed to passthrough image generation for a mixed-reality experience. A device may determine, using an eye-tracking system of a head-mounted device, eye-tracking data associated with a user of the head-mounted device. The device may determine, based on the eye-tracking data, a desired scene depth for the user. The device may instruct a first autofocus camera of the head-mounted device to adjust a first focus distance based on the desired scene depth and capture a first image of a real-world environment of the user. The device may generate a first passthrough image based on the first image. The device may display the first passthrough image to a first eye of the user via a first display of the head-mounted device.

  • FOVEAL REGION PROCESSING FOR ARTIFICIAL REALITY DEVICES
    Publication number: 20240338073
    Abstract: In one embodiment, a computing system may determine a gaze of a user of the computing system. The computing system may generate a foveated map based on the gaze to determine a sensor readout for an image sensor of the computing system. The foveated map may include several foveal regions. The computing system may determine the sensor readout including several zones corresponding to the image sensor based on the several foveal regions. Each of the several zones may indicate a readout resolution for an area of the image sensor for the respective zone. The computing system may capture a first image using the image sensor. The computing system may generate a modified first image based on the captured first image and the sensor readout.
