    Abstract: A head mountable device includes a front cover defining an external forward facing surface and a nasal bridge, a first rearward facing display, a second rearward facing display, a first forward facing camera, a second forward facing camera, and a controller electrically coupled to the first forward facing camera, the second forward facing camera, the first rearward facing display, and the second rearward facing display. The nasal bridge is disposed between the first forward facing camera and the second forward facing camera and the controller is configured to cause mixed reality video pass-through from the first forward facing camera to the first rearward facing display including a first image and from the second forward facing camera to the second rearward facing display including a second image.

    Abstract: A head-mounted device may include a display system and an optical system in a housing. The display system may have displays that produce images. The optical system may have Fresnel lenses through which a user of the head-mounted device may view the images. The Fresnel lenses may have concentric rings with slope facets and draft facets angled parallel to the chief rays. Light scattering in the Fresnel lenses may be reduced by coating the draft facets with opaque masking material and/or by aligning concentric rings of the opaque masking material that are supported on a transparent substrate with the draft facets. A central portion of the Fresnel lens that is free of facets may be enlarged to reduce scattering. The Fresnel lenses may have wedge-shaped cross-sectional profiles and may have outer portions that are thicker than inner portions. Gradient-index material may be used in forming the Fresnel lenses.

    Abstract: A pass-through camera in a head-mounted device may capture image data for displaying on a display in the head-mounted device. However, only low-resolution image data may be needed to display low-resolution images in the periphery of the user's field of view on the display. Therefore, the pass-through camera may only capture high-resolution images that correspond to the portion of the user's field-of-view that is being directly viewed and may capture lower resolution image data that corresponds to the real-world objects in the user's peripheral vision. To enable the camera module to selectively capture high-resolution images, the pass-through camera may include an image sensor with two or more pixel densities, a distortion lens, and/or one or more planar or curved mirrors. Any of the components in the camera module may be adjusted to change which portion of a scene is captured with high-resolution image data.
