Abstract: Various implementations disclosed herein improve the appearance of captured video by accounting for motion-induced blur, noise, lighting, and/or other factors related to the appearance of video captured by rotating or otherwise moving wearable electronic device. Some implementations reduce or eliminate camera motion blur during video capture by dynamically adjusting the exposure used to capture the video based on user motion. For example, exposure may be reduced to reduce the amount of blur during motion. Since such a reduced exposure captures a lesser amount of light, gain may be increased such that the captured video maintains a relatively constant image brightness in spite of the changing exposure over time.

Abstract: Various implementations disclosed herein reduce or eliminate camera motion blur during video capture by moving camera components to compensate for the motion. This may involve, for example, moving a camera component during each frame exposure to compensate for the motion (i.e., during image stabilization periods) and moving the camera component back in the other direction between the frame exposures (i.e., during re-initialization periods). The blur reduction techniques disclosed herein may be used in a live feed video environment in which one or more electronic devices simultaneously capture video via camera components and display the video as a live feed on a display.

Abstract: Various implementations disclosed herein include devices, systems, and methods that adjust a focus of a camera based on a distance associated with a determined user attention. For example, an example process may include obtaining sensor data from one or more sensors in a physical environment. The process may include determining at least one gaze direction of at least one eye based on the sensor data. The process may further include determining a distance associated with user attention based on a convergence determined based on an intersection of gaze directions of the at least one gaze direction, or a distance of an object in a 3D representation of the physical environment based on the at least one gaze direction. The process may further include adjusting a focus of a camera of the one or more sensors based on the distance associated with the user attention.

Abstract: An optical lens arrangement comprises a first Fresnel lens element and a second lens element. The first Fresnel lens element defines a flat surface side and an opposite faceted surface side defining wedge and draft faces. The flat surface side faces towards the eye of a user and the opposite faceted surface side faces away from the eye of the user. The second lens element interfaces with the faceted surface side of first Fresnel lens. The second lens element is selected from the group consisting of: a second Fresnel lens element, a singlet lens element, a doublet lens element and any combination thereof. The first Fresnel lens is proximal relative to the eye of the user and the second lens element is distal relative to the eye of the user. Head mounted devices (HMD) including these optical lens arrangements are provided. Methods of making such optical lens arrangements and HMDs are also provided.
